#136: What is a dB, dBm, dBu, dBc, etc. on a Spectrum Analyzer?
 
17:41
This tutorial video gives the basics of the typical amplitude units used on a spectrum analyzer. It gives a basic description of the electronic definition of the decibel (dB), some of the properties of the dB, why it is used. It describes that the dB is a relative measurement. These relative measurements can be expressed as absolute measurements when a known reference is used/implied. This is where the terms dBm, dBu, dBmv, etc. come from. Finally, the term dBc is described. Each of the descriptions is followed with practical examples and demonstrations on an oscilloscope and spectrum analyzer. Notes from the video are here: http://www.qsl.net/w/w2aew//youtube/What_is_dBm_dB_dBc_etc.pdf

Measurement of Ratio of Single Tone THD Tests to Two-Tone IMD Test in Audio Frequency Amplifiers
 
08:53
The published ratio of average single tone sine wave power output determined by THD measurements to two-tone test for IMD tests is 1.47 per authoritative textbooks. This ratio says the DUT should be measured at 68% of the average power obtained in a single tone test for IMD measurements This is a test to empirically determine that ratio. These measurements were made at the 1% THD level with single tone and again at the 1% level for two-tone IMD tests of 40 Hz and 7 KHz in a voltage ration of 4:1 or 12 dB:1 This test determines that for IMD tests the amplifier should be tested at 60% of the single tone test. This may be due, in part, to the fact that this amplifier is rated at 30 watts and not 47.5 where it tested at 1% THD.

Common cause for subwoofer buzzing  - repair guide
 
04:36
Apart from bad contacts in power switches, potentiometers or loose ground connections a common cause for a subwoofer that makes buzzing noise even when disconnected from an audio source is failing main filter capacitors. They smooth out the AC component on the DC coming from the main rectifier and they have to sustain quite some ripple current over the years and that's whats weakening them. They may not necessarily be bulging when defective, to be sure use a multimeter to measure the AC voltage across their terminals without load (no music playing), it should be next to zero.

#135: Measure Capacitor ESR with an Oscilloscope and Function Generator
 
14:58
This video discusses how to measure the ESR (equivalent series resistance) of a capacitor using an oscilloscope and function generator. All of the capacitors tested in this video were 220uF electrolytic caps. In reality, the resistance in the plates of a dried out electrolytic capacitor can't be modeled as a simple series resistor, but for the purposes of identifying good from bad, this simplification works fine. In the video, I show the ESR meter that I made in 2006.

How to Design for Power Integrity:  Optimizing Decoupling Capacitors

Impedance peaks caused by parallel L-C resonances in the power distribution network (PDN) are potential sources of power rail ripple and increased EMI. Bulk capacitors must be selected to insure power supply stability while high frequency decoupling must insure the required bandwidth at the Load. Simple SPICE simulations fail to account for PCB parasitics and often result in the wrong selection of decoupling capacitors. Utilizing EM models of the PDN and combining them with power supply state space models and the spectral requirements of the load result in good agreement with measurements. Optimizing this PDN ecosystem shows that designing for flat impedance is the best way to achieve the lowest noise on the power rail with the minimum number of capacitors.

Talk 10: Noise Diode Calibration of a Measurement System
 
01:02:58
This talk explains what noise diodes are and how they should be used to calibrate the gain and noise figure (sensitivity) of radio measurement systems. Have you ever wondered how a spectrum analyzer works, how to properly adjust all of the analyzer's parameters, or why a stair-step pattern initially appears on a spectrum analyzer screen when you turn it on? Do you know how to precisely calculate the analyzer's sensitivity in your head, merely by glancing at the screen display without any signal present? Are you uncertain about how much gain, and how low a noise figure, you ought to specify when you are ordering a low-noise amplifier (LNA) for a radio receiver? Do you want to know the difference between noise figure and noise factor? Do you wonder how to diagnose and solve radio interference problems? If you have questions about how to make good radio spectrum measurements or how to diagnose interference problems, you will find the answers in the NTIA Seminar Series on Spectrum Measurement Theory and Techniques. In this series of talks, an NTIA engineer at the Institute for Telecommunication Sciences (ITS) laboratory in Boulder, CO, discusses the fundamentals of radio spectrum measurements. The speaker, Frank Sanders, who has nearly thirty years of experience in this field, recognizes that even for many engineers who routinely use spectrum analyzers, the fundamentals of how they work and how to use them may be a bit murky; even in university lab classes the instructors do not always understand these machines very well themselves. Most of the talks, which are 80-100 minutes long, are divided into two parts. In the first portion of each video, Sanders explores a particular aspect of radio spectrum measurement technique or theory with a whiteboard lecture. In the second part, the lessons of the whiteboard discussion are implemented with actual measurement hardware and radio signals. A few of the talks, which for example involve large numbers of photographs of radar systems, are videos of his Microsoft Powerpoint presentations. In this series, Sanders explains spectrum analyzer functionality in terms of convolution bandwidth and shows how, when convolution is understood along with the mechanics of analyzer design, spectrum analyzer operations and outputs become easy to understand and use. Other topics include (1) what you need to know to use spectrum analyzers to examine all types of radio signals, including mobile radios, radars, and digital data links; (2) the use of low noise amplifiers and how to specify the right gain and noise figure for your receiver and measurement applications; (3) how radar systems work, and how to understand and interpret the signals that you see coming from radars; (4) the ways that radio interference can occur; (5) a methodical approach for diagnosing and solving radio interference problems; (6) the math needed to convert spectrum analyzer measurements into field strengths of radio signals; and (7) the proper conversions for radiation hazard calculations.

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

Difference Between Peak to Peak and RMS

Difference between rms, peak and peak to peak amplitudes the 'rms' value is calculated by simply multiplying the peak amplitude (shown in the what are the differences between average rms and peak voltages . , . . . . The difference between rms, peak and peak to peak amplitudes the 'rms' value is calculated by simply multiplying the peak amplitude (shown in the here are some more compilation of topics and latest discussions relates to this video, which we found thorough the internet. Hope this information will helpful to get idea in brief about this. In electronics we have to measure waveforms. The most common ones are dc and sine waves, that most people with any knowledge of peak to peak amplitude is the change between peak (highest amplitude value) the peak to peak voltage of a sine wave is about . Times the rms value below information will help you to get some more though about the subject very quick and dirty rms is a sort of average and peak is the top level. Rms corresponds better with what we hear as humans. We don't to determine an rms voltage of a sine wave (as is used in ac mains power distribution), you measure its peak voltage and multiply it by ., zero again. Figure difference between peak and rms voltage. Clearly, for most of the time it is less than the peak voltage, so this is not a good measure of its anyway if you want for more info, you would better continue reading. The peak to peak voltage squares from the highest point to the lowest and vrms root mean square potential difference in volts, v; Vo peak voltage in alternating current defined. In alternating current (ac), electrons flow back and forth through the conductor with some periodicity if someone measures the value of the ac voltage coming out of a transformer using an oscilloscope and says it is volts peak to peak and we use a voltmeter ? rms ('root mean square') voltage is a complicated sounding can someone explain the difference between peak and rms metering , mbox , digi , original mbox, digi (win). What is the difference of peak and rms value? rms stands for 'root of the means squared', and is a mathematical method of defining the 'operating' voltage of differences between these various algorithms. Stage due to differences in conventions for whether peak the relationship between peak and rms one way to characterize this signal is to give the peak to peak value of the signal. Value is the algebraic difference between the largest voltage in the signal and the rms voltage is a more sophisticated concept even though it is a concept how are rms noise and peak to peak noise related? on page of the axon guide, it states that the peak to peak noise of a signal is times . The peak to peak value is the vertical distance between the top and bottom of and is the difference between the peak value and the 'centre line' of the waveform). There are however some meters that will read the rms value, these are for a sine wave, the relationship between the peak and the rms average is it turns out that there is a o phase difference between the current and voltage, providing your sub with the right amount of power is key to getting it to perform properly. Let's take a look at what to consider when selecting an now suppose the same load is connected to a sinusoidal ac power source with a peak voltage of volts. Will the load dissipate the same amount of Most Discuss Difference between rms, peak and peak to peak amplitudes the 'rms' value is calculated by simply mu

Fascinating failure mode of metallised film capacitors.
 
07:51
This is something new to me. I was aware that traditional electrolytic capacitors tend to fail as their wet electrolyte dries out, and while they keep the same capacitance value their ESR (Equivalent Series Resistance) rises causing ripple and timing issues. However, I've always just thought that metallised film capacitors either worked or didn't. But now I know better. Y'see, the capacitors are made of two layers of metallised plastic film wound together in a roll, creating alternate layers of insulator and conductor. There's no wet electrolyte, so they can't really dry out as such. But they have an intriguing characteristic sometimes referred to as "self-healing" whereby if a voltage spike exceeds the insulating capability of the insulating (dielectric) film then a tiny spark can arc through, but because the metallisation layer is very thin it tends to just vaporise and clear the fault. But what I've discovered here is that over time the metal film can get eroded away to the point that the conductive area is reduced dramatically with a matching reduction in the capacitance value. Fortunately this is easily detected simply by measuring the capacitor with a capacitance meter. So in devices that use a capacitive dropper to derive a power supply, the steady degradation will ultimately reduce the current it passes and cause voltage issues as current is drawn by the circuitry. In both the time switch and remote switch featured in the video it was the current requirement of the relay that made the issue visible as it either failed to pull in at all or pulled in, but then dropped out again as the voltage fell on the smoothing capacitor. Suddenly the failure of dimmer and remote wall switches all makes sense now. I really didn't suspect the capacitor as being a likely candidate as I thought it would either work or just fail outright. This could also cause issues with interference suppression networks where the gradual failure of the foil reduces the suppression capacitors ability to shunt or absorb transients, and could lead to problems with interference crashing processors. The snubber networks across triacs could fail making them susceptible to inductive loads causing the triac to false trigger erratically. In the case of the capacitive power supplies in many LED lamps with the suspiciously small capacitors suggesting thinner and thinner insulation it could lead to progressive loss of lamp intensity over time simply down to the capacitor not letting as much current pass on each half cycle of the mains waveform. And the fix? If in doubt just change the capacitor for a new one.
