Op-Amp: CMRR (Common Mode Rejection Ratio) Explained (with example)
 
10:10
In this video, what is Common Mode Rejection Ratio (CMRR) in op-amp and what is the importance of CMRR has been explained with the example. What is CMRR? CMRR is the ratio of differential gain and the common mode gain. For ideal op-amp, the value of CMRR is infinite, but for practical op-amp's the value of CMRR used to be in the range of 80 to 100 dB. Common mode gain is the gain of op-amp when same input is applied or same input is present at both input terminals. Op-Amp in open loop condition acts as a differential amplifier and amplifies the difference between the two input terminals. So, if both inputs are equal then the output of the op-amp in ideal condition should be zero. But actually, some output used to be present at the output terminal. And the ratio of this common output to the input voltage is known as the common mode gain. For ideal op-amp, the value of common mode gain should be zero. But practical op-amp has some finite value (less than 1) of common mode gain. Noise is the main source of common mode input signal. And op-amp should be able to suppress this noise as much as possible. And how well it is able to suppress this noise is represented by this CMRR. The timestamps for the different topics covered in the video. 0:20 What is CMRR and what is the importance of CMRR. 4:58 Example This video will be helpful to all the students of science and engineering in understanding the concept of CMRR in op-amp.

How To - Function Generator FG-500 modify power supply
 
03:28
This video explains how to modify power supply for FG-500 Function Generator. This was trial and error as i could not find any guides on this topic on the internet. In my test i ended up blowing a capacitor. The problem was the way i hooked it up the first time, in order to change from battery to external power, you have to disconnect the wires coming from J8 and J7 and just connect the Positive lead from power supply to J8 and to use battery power just connect J8 and J7 back together. J8 is a White wire on my circuit and J7 is a Red wire. check out my website www.electrons.tk

Stability Analysis of Power Supplies with the Bode 100
 
05:52
Note: We have a new and extended video on this topic! Check out: https://youtu.be/0kZ0G7sNuik In this video tutorial we show how the vector network analyzer Bode 100 is used to perform stability analysis of a linear voltage regulator. We use the Bode 100 in conjunction with the B-WIT 100 wideband injection transformer to measure the open loop gain of a LM317 linear voltage regulator and read out the gain margin and the phase margin. By demonstrating the measurement of the stability of the DC power supply some nice features of the Bode Analyzer Suite like the shaped level function are shown. The shaped level function allows changing the output signal level of the Bode 100 over frequency. This allows to reduce noise where necessary, but to keep the level low in order to not overdrive the control loop. The VNA Bode 100 can be also used to visualize the influence of input voltage and load current changes on the stability of a control loop. To gather further information about the methods used to measure quality indicators of a DC power supply containing DC/DC converters please download our application note at: http://www.omicron-lab.com/bode-100/application-notes-know-how/application-notes/dc-power-supply-analysis.html Used Measurement Equipment: Bode 100 -- The Bode 100 is a vector network analyzer that serves as a frequency response analyzer, a gain phase meter and impedance meter as well as a sine wave generator. It can be controlled via the Bode Analyzer Suite, a graphical user interface. An OLE compatible automation interface allows easy implementation into automated systems. B-WIT 100 -- The wideband injection transformer B-WIT 100 is used for inserting signals into a high variety of electronic circuits such as control loops or switched mode power supplies.

What happens when a powerful E.M. signal on 20 KHz is strayed back into the power supply? tips
 
06:03
Important (forgotten to draw in the schematic!): connect a 4 MOhm potentiometer with a 10 K resistor in series between the base and the collector of the transistor. Align it to maximum effect. Correction: 1/ten millionth = 100/ten millionth of the H.F. (A.C.) voltage parallel to the tank circuit is added to the counter and oscilloscope input.. WARNING: don’t damage your oscilloscope while doing these experiments, never connect the input socket of your oscilloscope to a High Voltage transformer or a resonant circuit without having an idea about the HF power that is strayed out. Your scope can/will be dead immediately..... Also: don't connect a normal voltmeter (= not equipped for High Voltages) to a High Voltage source or an A.C. source straying out an E.M. frequency on its resonance, without having an idea about the strayed out power. Your (hobby) Voltmeter can burn out immediately. For safety reasons (to lower down the voltage to the oscilloscope and the frequency counter inputs) I used a voltage divider with a ratio of 100 to 10000000 (100 compared to ten million) parallel to the H.F. tank circuit/coil. Reason: the tank circuit is on its electromagnetic resonance frequency, that means that the HF energy is “swirled up” to its maximum, a quite unpredictable amount of HF/E.M. energy, with energy “peaks”. Such a voltage divider (in general) will only work properly with low power (!) tank circuits on their resonance frequency (say max 3 Watt). I don’t want to make anyone shy, but don’t use your expensive (hobby) measuring instruments in your shack to get basic insight in what is happening here. Good idea: lay the probe of your scope down on the table, without any physical contact, a few centimeters next to the High Voltage generator or E.M. straying oscillating circuit. You can already see the waveform in that case. Or: make a “pickup coil” of (say) 8 windings, connect it to your scope-probe (crocodile clip-top), and lay that pickup coil on the table, next to the E.M. straying circuit. You can surely pickup the HF signal in that case. Video showing the effect of a powerful 20 KHz oscillator that sends HF energy back into the (DC) Power supply. The DC Digital Voltmeter is, in that case, completely disturbed and does not give a reading any longer. The pointer of the AC Ampère meter moves out, the DC Ampère meter shows no reading. So that is what you can expect when you work with powerful High Frequencies. By the way: I mounted a Pi filter in the power supply lead, that had no effect. Correction: on 3.50 I say “that the circuit takes AC out of the power supply”, but the BU 2708 AF H.V. transistor was driven with a DC source of 40 Volts. So that cannot be true, on the other hand: could be that the DC was “chopped” on the frequency of the oscillator. What exactly happens in the Power Supply needs much more study, I don’t want to spend time on that. Video is a part (in fact part 4) that belongs to another video where I showed “3 experiments to make an ultrasound water bath”. All failed experiments, by the way (!). So only experimental information here.

Digital Variable power supply
 
01:55
The advent of industry, hospitals, retail outlets and computers and computer controlled equipment entering the rural domain of India has necessitated the requirement of variable power supply for variety of equipment. For meeting this requirement a multipurpose supply source is envisaged. Until now, the digital supply has carried a variety of meanings: one whose parameters or functions are set digitally by external logic signals; or a power supply for a "digital system," like a cell phone; or a power supply providing a digital readout. The greater functionality and new monitoring features of today’s power supply requires more sophisticated control and communications. In addition, requirements for lower costs, smaller form factors and compressed development cycles continue to escalate, pressing power supply designers as never before. The digital power supplies are proving to be a better and futuristic option over the analog power. The architecture of the microcontroller is out of the preview of this paper. A variable power supply is one where you can continuously adjust the output voltage to your requirements. The conventional controlling method of variable power supply that uses manual interference (using a rheostat) has been replaced by a servo motor which is controlled by a micro-controller. This in turn reduces the pain of adjusting the rheostat manually and also increases the efficiency of the system. Varying the output of the power supply is the re-commended way to test a project after having double checked parts placement against circuit drawings and the parts placement guide. Aimed at solving the practical problems envisaged in the power supply to the rural areas of India .It is a practical application of software for the controlled power supply from a single platform to a varied variety of equipment expected to be used in hospitals, BPOs etc. The software programming has been incorporate d using C language and has been kept out of the purview of this presentation as the program itself is a subject of independent presentation. The design has been made incorporating user friendly features and easy usage for the operation. CONTACT ON : 9503784350 , 020-65001020.

Display Port No Signal FIX !! [Step-by-Step in Description]
 
05:02
Hi everyone. I ran into an issue where my Display port wasn't working after the computer went to sleep. After searching online and trying different fixes for 2+ hours, I finally came across a very simple way to fix this issue. Please consider Subscribing if this video helped you out! Subs help my channel be able to monetize which allow me to produce additional content :) Steps to fix the Display Port: 1. Turn off the computer and either unplug it from the power source or turn off via the Power Supply's power switch. 2. Turn off your monitor and then unplug it from the power source. 3. Wait 30 seconds. 4. Plug the monitor back on, turn it on if it doesn't do so automatically. 5. Plug the PC back on or flip the PSU switch back to on. 6. Turn the PC back on and if this fix is applicable, your Display Port will now work again. NOTE: Make sure no other video cables are plugged in to the GTX 1080 or other GPU. Just have the faulty Display Port plugged in with the Display Port cable connected to the monitor. Also, if you suspect driver issues, connect the computer via HDMI or DVI and reinstall the display drivers again. You may need to use older drivers if the newest drivers are breaking your ability to use Displayport. I hope this saved you guys from all the effort and possible RMA's! Thanks for watching :)

How to Make Living Off The Grid Easy With PLC Automation
 
22:53
In this video, I show off the system that I designed, fabricated, installed and programmed for our off grid ranch. At the heart of the system is the Click PLC purchased from www.automationdirect.com. The PLC has many different functions on the ranch. The primary function is to start and stop our generator. It can receive a signal from my Outback systems Mate 3 controller for auto generator start control, as well as use the interval timers that I installed in the control panel for manual start operation. In manual start mode you need to enter the time in hours to the display, then press the start button, and the system takes over...Running the accessory power, glow plugs, then finally cranking over the generator until it sees a 240v signal coming back into the control panel indicating the generator is running. Another thing that it does is allows the generator to run for a while before engaging a 60 amp contactor that applies the load to the generator. Once the generator has ran for either auto start or for the programmed interval, it unloads the generator by releasing a 60 amp contactor, lets the generator run for 15-20 seconds, then shuts it down. This ensures that additional wear and tear is not caused to the generator by shutting down under load. Other functions include managing the PWM signal from my second outback charge controller, which is set in diversion SSR mode. This means that once the batteries are full and solar power is still coming in from the solar panels (Excess power) it will start modulating the signal to allow power to go to our hot tub. We sucessfully kept the hot tub heated all winter long. When the generator is running the system switches the feed for the hot tub power over to the generator, which means we get plenty of energy to keep the spa hot. The system will be changing in the future, I do plan to use these click PLCs to create a solar tracker for the panels that are on the roof of the shipping container. I also need to add an AC input module so that I can better monitor the power output of the blue inverter (The blue inverter was sent to my from a company called FoxPower, they were originally going to send a 4000 watt unit for me to review on video...I asked them if they can just send me a 12,000 watt unit and have me pay the difference. They went for it and now I have two really nice inverters.) Back to the point - I want to monitor the power output of the blue inverter. It is critical, because if the power goes out, then I lose AC power that I use in order to close the 60 amp contactor that loads the generator. This means I can end up being stranded without being able to charge the batteries (It's practically a catch 22). Either way, this was a long description, and I mainly wanted to get some info in for you guys to clarify some of your questions on. Thanks for watching and I'll see you in the next video.

Neurons or nerve cells - Structure and function | Human Anatomy | Biology The nervous system is an essential part of the human body that helps in the transmission of signals across the various parts of the body, that is, it releases messages back and forth from the brain to the different parts of the body, and also helps in the coordination of voluntary and involuntary actions of the body. At the cellular level, the nervous system consists of a special type of cell, called the neuron, also known as a "nerve cell". The neurons connect to each other using a synapse (which is a structure that acts like a pathway connection that transmits the signals to the other cells) to form the nervous system. Neurons have special structures that allow them to send signals rapidly and precisely to other cells by providing a common pathway for the passage of these electrochemical nerve impulses. Neurons are responsive in nature, by which we imply that Neurons response to feelings and communicate the presence of that feeling to the central nervous system which in-turn is processed and is sent to the other parts of the body for action. The neurons are the basic constituents of the brain, vertebral spinal cord, the ventral nerve cord and the peripheral ganglia( which is a mass of nerve cell bodies). Nervous system Neurons can be categorized into three types: sensory neurons, motor neurons and inter neurons. Sensory neurons allow us to receive information from the outside world through our senses. The sensory neurons evoke the sensation of touch, pain, vision, hearing and taste. These are usually present in the sensory organs, like the eyes, inner ear and so on, which send these signals to the spinal cord and the brain. Inter neurons communicate and connect with each other, and represent the majority of the neurons in our brain. They allow us to think see and perceive our surroundings. Motor neurons are neurons that receive impulses from the spinal cord or the brain and send them to the muscles causing muscular contraction, and these also affect the gland secretion. A typical neuron has a "soma" in its centre, which contains the nucleus of the cell. And hence this is where the protein synthesis occurs. The neural function is based on the synaptic signalling (the pathway that helps in the transmission of signals) process, which is partly electrical and partly chemical. The electrical aspect depends on properties of the neuron's membrane. Every neuron is surrounded by a plasma membrane, which is a bilayer of lipid molecules that comprise of various protein structures. A lipid bilayer is a powerful electrical insulator, but in neurons, many of the protein structures embedded in the membrane are electrically active. Cell division cannot take place in neurons as they lack one of the two cylindrical cellular structures that aid in cell division. This is consistent with a simple cell division nature of the cell. Dendrites are extensions of the cell with many branches, whose structure can be called as a "dendritic tree" . They project from the cell body and are sometimes referred to as fibres. They are also called as afferent processes because they transmit impulses to the neuron cell body . There is only one axon that projects from each cell body, which is a finer cable-like projector. It is usually elongated and it carries impulses away from the cell body, that is, away from the 'soma'. It is an efferent process. many axons are surrounded by a segmented white fatty substance called myelin sheaths.

What is RFID?  How RFID works?  RFID Explained in Detail
 
10:10
In this video, RFID (Radio Frequency Identification) Technolgy has been explained. So, in this video, what is RFID, what is inside this RFID system, how RFID works, and application of RFID have been explained. What is RFID? RFID is technology which works on radio frequency and it is used for the auto-identification for the different object. The RFID system mainly consists of two parts. 1) RFID Reader or Interrogator 2) RFID Tags In this RFID system, this RFID reader continuously sends radio waves of a particular frequency. If the object, on which this RFID tag is attached is within the range of this radio waves then it sends the feedback back to this RFID reader. And based on this feedback, RFID reader identifies the object. RFID tags: Now, three different kinds of RFID tags are commercially available. 1) Passive tags 2) Active tags 3) Semi-passive tags These passive tags do not have any power supply. They used to get their power from the incoming radio waves from the Readers. While active tags have a power source for their internal circuitries. And for sending the response to the reader also, it uses its own power supply. In the case of semi-passive tags, they have a power supply for internal circuitries, but for sending the response it relies on the radio waves received from the Reader. Operating Frequency: This RFID system is mainly operated in three frequency bands. 1) LF: Low-Frequency band 2) HF: High-Frequency band 3) UHF: Ultra High-Frequency band The exact frequency of operation varies from country to country. Operating Principles: Most of the RFID systems operate on any of this two principles. 1) Load Modulation 2) Backscattered Modulations Applications of RFID: 1. Institutions: Library, Hospitals, Schools, and Colleges 2. Transportation and Logistics 3. Access Control 4. Sports 5. Animal Tracking Timestamps for the different topics in the video is given below: 0:40 What is RFID? 1:56 What is inside this RFID chip? 4:42 Operating Frequencies for the RFID Systems 5:27 Working Principle of RFID Systems This video will be helpful to everyone in understanding the concept of RFID Technology.

Manually Test a (PSU) Power Supply With a Multimeter by Britec NOTE: This testing applies only to the standard ATX PSU, it does not apply to proprietary PSU's (ie: older Dell's ) which use a different pinout arrangement for their ATX connectors (non-standard). 20 and 24-Pin Connectors: The 24-Pin connector has an additional 4 pins attached to one end of the connector. The top 20-Pin section is electrically identical to the original 20-Pin ATX connector. Due to the additional connections the numbering sequence changes, so if you have a 24-Pin connection then make that adjustment when comparing with a 20-pin +3.3v pins 1, 2, 11 (Orange wires) +5V pins 4, 6, 19, 20, (Red wires) +12V pin 10 (Yellow wires) -5V pin 18 -12V pin 12 Need help with your computer? http://www.briteccomputers.co.uk/forum

How Cell Towers Work: Hands-On!
 
09:28
Fun fact: when I was selling mobile phones back in 2004, I would spend the store's slow days taking online training courses reserved for my employer's engineers, fascinated by the networks that made mobile phones work. Twelve years (and a change of career) later, my network curiosity still burned strong. So I asked AT&T to let me go hands-on with a cell site – and to my great surprise, the carrier said yes! Come along as I scope out not one, but two cell sites: one hidden in the steeple of a church, the other perched high atop the tallest mountain in the Northeast. In the process we'll learn about RF energy, what happens when the power goes out, and why the term "tower" isn't always accurate. [SUBSCRIBE] https://www.youtube.com/channel/UCSOpcUkE-is7u7c4AkLgqTw?sub_confirmation=1 [ABOUT THIS VIDEO] MrMobile's Tower Tour was produced based on a pitch by MrMobile to AT&T in the Spring of 2016. To make this video possible, AT&T provided access to two cell sites and several network engineering personnel. AT&T also reviewed MrMobile's final script for technical accuracy, but no editorial changes were made as a result of the company's input. Travel expenses were entirely paid by MrMobile/Mobile Nations, and there was no consideration paid to MrMobile by AT&T for the production of this video.

UNI-T UTD1025CL Handheld Digital Oscilloscope — Video Review
 
07:24
UNI-T UTD1025CL: http://toolboom.com/en/Handheld-Digital-Oscilloscope-UNI-T-UTD1025CL.php UNI-T UTD1025CL is a single channel lightweight, handheld scopemeter with 25 MHz bandwidth and 200 MS/s sample rate. UNI-T UTD1025CL handheld digital oscilloscope also performs multimeter measuring functions: AC/DC voltage and current, resistance, capacity, diode and continuity tests. The device is provided in a handy bag. Accept for the oscilloscope, the bag may carry some useful tools - there's a special partition for that. The oscilloscope package contains all you need - User manual - oscilloscope measurement probes - mini-USB cable - CD with software - power cable - probes with alligator clips - multimeter measurement probe - bypass adapter for measuring current up to 10 A - static power supply unit The manufacturer managed to produce a full-function oscilloscope in a housing of standard multimeter size. The housing material quality is high, the device may be conveniently held with one hand and the rubber plastic prevents the device from slipping out of the hand. The scope design consists of the following elements. The front panel houses a 3.5 inch display and controls. The left side houses the calibration signal output. Power supply unit and USB connection are located on the right side. The upper part - oscilloscope and multimeter connectors are here. The back panel houses a lithium-polymeric battery with a capacity of 3600 miliampere per hour. There is also a convenient support stand. Let's refer to the oscilloscope technical specifications. It is a portable single-channel digital oscilloscope with 25 MHz bandwidth, and 200 MHz sampling rate. There are powerful capabilities of signal triggering: Edge, Pulse, Video and Alternate. In multimeter mode, the device allows measuring AC and DC voltage and current, resistance, capacitance, as well as performing diode test and continuity check. There is a possibility of PC synchronization. The scope has a function of step-frame signal recording. To enter the record mode press STORAGE/RECORD button, then press F1 button to select the recording mode. F4 button starts recording. The right upper corner of the screen displays the data about the total frame amount and the current frame number. The device memory allows storing 5 records with 300 frames each. Any time you may stop recording and have a closer look at the details of interest. You may move to any frame using navigation buttons. You need to save the signal for further data processing or transfer - 5 memory slots are available. This signal may be transferred and examined on a PC using a special software. We'll demonstrate the operation of the scope with test signals with 4 V amplitude: sin 1 kHz; sin 100 kHz; sin 1MHz; sin 5 MHz; sin 10 MHz; sin 15 MHz; sin 20 MHz; and sin 25 MHz. Behind the bandwidth edge, namely at 30 and 40 MHz, the amplitude roll-off occurs, but the scope shows signal delivery and frequency. Now let's have a look at a square waveform: 1 kHz signal; 100 kHz signal; 1 MHz signal; 5 MHz signal; 10 MHz signal; 15 MHz signal; 20 MHz and 25 MHz waveforms have a sin shape, as expected. To sum up, first we should like to note that UTD1025CL has all the functional oscilloscope characteristics in a compact housing. However, its price is rather affordable compared to other equivalent models. It is an essential tool for operation on-site, taking into account the multimeter function and long battery operation. Uni-T have once again managed to create a worthy measuring device. http://toolboom.com/en/Measuring-Equipment/Oscilloscopes - digital oscilloscopes from ToolBoom store

POWER SUPPLY CABLE SETUP PC-COMPUTER | HOW  Install or Replace a power supply Possible

POWER SUPPLY CABLE SETUP PC-COMPUTER | HOW Install or Replace a power supply Possible/// A simple general purpose desktop power supply used in electronic labs, with power output connector seen at lower-left and power input connector (not shown) located at the rear A power supply is an electrical device that supplies electric power to an electrical load. The primary function of a power supply is to convert electric current from a source to the correct voltage, current, and frequency to power the load. As a result, power supplies are sometimes referred to as electric power converters. Some power supplies are separate standalone pieces of equipment, while others are built into the load appliances that they power. Examples of the latter include power supplies found in desktop computers and consumer electronics devices. Other functions that power supplies may perform include limiting the current drawn by the load to safe levels, shutting off the current in the event of an electrical fault, power conditioning to prevent electronic noise or voltage surges on the input from reaching the load, power-factor correction, and storing energy so it can continue to power the load in the event of a temporary interruption in the source power (uninterruptible power supply). All power supplies have a power input connection, which receives energy in the form of electric current from a source, and one or more power output connections that deliver current to the load. The source power may come from the electric power grid, such as an electrical outlet, energy storage devices such as batteries or fuel cells, generators or alternators, solar power converters, or another power supply. The input and output are usually hardwired circuit connections, though some power supplies employ wireless energy transfer to power their loads without wired connections. Some power supplies have other types of inputs and outputs as well, for functions such as external monitoring and control.

In all cases, the turn signal switch is also in charge of the hazard lights and to make matters worse, the hazard and the turn signal switch is often a separate unit. Here in this section, we'll not concentrate on the hazard switch, but simply explain how to wire the entire turn signal system. The idea is to offer a way to make the turn signals operational if you have no parts available, due to the vehicle being out of the parts market, being too rare or just due to the high costs. In actuality, this wiring arrangement can be used even if you have no turn signal switch, which would then be substituted using standard buttons or flip switches. This circuit also employs a regular flasher unit right at the 12 volt input. The flasher unit feeds both relays. This is done for the sake of efficiency and to reduce costs. The only drawback to using one flasher is that whenever the hazard is activated, the lights will flash at a faster rate. Let's analyze this circuit: Power is fed from the 12 volt supply, through the fuse and to one side of the flasher unit. The other side of the flasher feeds terminals....

LTspice: AC Analysis
 
06:23
Simon Bramble - Field Applications Engineer Sometimes the frequency response of a circuit is more important than looking at the individual voltages or currents at a specific part of the schematic. LTspice (http://www.linear.com/ltspice) can help you achieve this with its AC analysis function. This video shows you how to perform a basic AC analysis in LTspice as well as point out some capabilities you might not already know about...

RF ISM Power Supply pt. 2
 
03:39
Book available soon at our Non Profit Green energy web http://www.lablancinventors.org/ visit our web site for more pics of this radio we are writing the book on at http://www.lablancinventors.org/pics This is a teaser for the 6 MHz to 27.2 MHz radio frequency transmitter prototype we are designing and building. The book to build this unit will be available in late 2016. The high voltage vacuum tube power supply is Hammond 278CX transformer at 800 volts filtered DC X 535 ma. (that's 428 watts available). This HV power supply has a built in 500 watt Staco 501C Variac to adjust it. It's filtered with 500uF X 900 VDC caps and uses a DC choke to also regulate and filter it. The filament power supply is also filtered with 47,000uF caps and 10 amp DC choke and voltage regulated with adjustable circuit. The Screen grid power supply is also separate and adjustable and zener diode regulated. The PI network has a 7 inch long adjustable coil and 2 adjustable multi-turn air caps to tune the tank circuit and load. There are pin jacks all over this unit to check amps, volts and frequency. It has built in frequency meter and Hobbs meter to track time use. Adjustable Pi network is also for changing frequencies and adjusting for loading conditions. Designed for 50 ohm output. Can run function generator input instead of easy changeable crystals. Can run 3 large socket vacuum tubes like the 6L6GC and 1 KT88. It also has provisions for 4 small socket vacuum tubes or RF transformer in small socket case. Can make an armature Radio transmitter with these provisions. An air cooled vacuum tube cooling system that controls tube temps as well as transformers, heat sinks and control transistor for the filament power supply is powered with 2 large 120 VAC box fans. ................................................................... Note: the Plate and filament power supplies weigh 40 pounds together. ------------------------------------------------------------------------------------------------------------------- Industrial, Scientific and Medical (ISM) equipment ISM equipment The term Industrial, Scientific and Medical (ISM) generally refers to equipment or devices that utilize radio frequency energy to perform work. The IEC defines the term; “Qualifies equipment or appliances designed to generate and use locally radio frequency energy for industrial, scientific, medical, domestic or similar purposes, excluding applications in the field of telecommunications” Some Examples of common ISM equipment are medical diathermy equipment, industrial heating equipment, and magnetic resonance equipment. Equipment making use of RF energy in a similar way, but used for domestic purposes, also comes under the definition of ISM equipment, if they utilize RF energy to perform work; some examples of typical devices are microwave ovens, jewelry cleaners, and ultrasonic humidifiers. It should be noted, that while ISM devices utilize specific ISM frequencies within defined ISM spectrum allocations, the fact that a devices makes use of an ISM frequency does not define the product as an ISM device. For example, the commonly used 2.4 GHz spectrum for wireless networking, centered on 2.450 GHz and ranging from 2.4 – 2.5 GHz, is a designated ISM frequency band. In the case of wireless networking, the frequency is used for telecommunication, and telecommunication use is excluded under most definitions of ISM equipment. In that case, the wireless networking device would be classified under other rules, designed for unlicensed intentional radiators. Telecommunication equipment usually comes under the definition of Information Technology Equipment (ITE). In the United States, C.F.R. Title 47, part 18 covers electromagnetic interference requirements for Industrial, Scientific and Medical (ISM) equipment. Some product types require certification prior to marketing or selling in the U.S. reprinted from: http://www.celectronics.com/training/...
#137: Why your Function Generator's output voltage reading can be wrong
 
05:15
This video reviews the two most common reasons why the output amplitude setting on a function or signal generator doesn't match what is read on an oscilloscope. This can be due to an incorrect attenuation setting on the scope, but is most commonly due to the fact that the generator is not presented with the load impedance that it is expecting. To correct this most common case, you can either use the correct load impedance, or tell the generator what load you are presenting it with.

#84: Basics of Ferrite Beads: Filters, EMI Suppression, Parasitic oscillation suppression / Tutorial
 
11:52
This video discusses the basics of ferrite beads, and their uses for basic filtering applications. It discusses and demonstrates how ferrites act as resistors at high frequencies, and how this is used for EMI/RFI Suppression, improved power supply filtering, parasitic oscillation suppression, and others. The affect of the frequency dependent resistive characteristic of the ferrite beads is demonstrated by showing its effect on a swept RF signal, its effect on the rise/fall time of a digital signal, and its effectiveness of eliminating parasitic oscillation. Here are some links to the other videos mentioned in this video: Harmonic content of square waves: http://www.youtube.com/watch?v=eC36AqL5mw8 Analog Oscilloscope Bandwidth Considerations: http://www.youtube.com/watch?v=oZ1Dv2dVGkU

#79: Op Amp Power Supply Considerations: split, single, virtual ground, etc. - a tutorial
 
15:09
This video discusses the power supply considerations for op amps. It talks about split or dual power supply and single supply operation, and why the op amp often doesn't care which you use! It shows how traditional op amps designed for split supply operation can be used in single supply applications. The most important consideration generally is taking care of where the input and output voltages are with respect to the supply rails. The input voltage and output voltage range specifications are examined in a datasheet. The operation of a op amp in a single supply application is examined on an oscilloscope. This operation is compared to a modern rail-to-rail op amp in the same circuit. Notes from the video are here: http://www.qsl.net/w/w2aew//youtube/opamp_power_supplies.pdf
