EEVblog #594 - How To Measure Power Supply Ripple & Noise
 
37:44
Fundamentals Friday Dave explains what the ripple and noise specifications on a power supply is and how to measure it using different methods on both analog and digital oscilloscopes. From bad techniques through to good, showing the effect of each one. Traps for young players aplenty in this one. How do you detect common mode noise issues and ensure that the signal you are measuring is really coming from your device under test? Single ended & differential measurement, DIY coax solutions, termination, analog vs digital oscilloscopes, bandwidth limiting, and even oscilloscope probe coax construction issues. It's all here.

How to (Safely) Measure Full Wave Rectified AC Mains On An Oscilloscope
 
10:24
Video response to EEVblog #279 where Dave talks about pitfalls when connecting your oscilloscope's ground lead to your circuit. Great video, but he left out and especially sneaky scenario which has caused problems for me (and others I'm sure) in the past. Sneaky because it looks fine on paper, but the problem arises because of the way homes and offices in the US are connected to mains. I'm not sure how many countries are like this, but I know there are at least a few, so worth watching and being aware of regardless of where you live.

Measuring and Observing Current using Oscilloscope and Shunt Resistor
 
05:40
WARNING: A power transformer in this video is connected to 115 volts. Please consult a professional if not sure; otherwise, may cause serious injury. Observing the Waveform of the current (amperage) going through a circuit board by using oscilloscope requires a shunt resistor and isolation of the circuit. This video shows one way to do it. A transformer was used in this video to isolate the entire circuit due to the alligator clip of the probe referenced to the ground. Also, the shunt resistor is a one-ohm resistor with 0.1% tolerance, and has maximum rating of 8 watts. If just measuring the average amount of current, then a floating multimeter should be sufficient. If you are using a switching power supply, the circuit still needs to be isolated. Another alternative is to use a differential probe for the oscilloscope, or use an isolation transformer between the mains and the switching power supply. This type of transformer are usually 1:1, and the primary and secondary windings must be completely isolated from each other. The shunt resistor may be smaller than one ohm, but may be out of range for the oscilloscope to measure, or may require an active probe with built-in amplifier to measure microvolt range.

Effect of power cut on Hot Water Relay and SwitchIt
 
04:42
A demonstration of how a "SwitchIt" device (inside the house) and a standalone ripple control receiver (in meter box) and relay are both reset to the ON position following power being restored during what was meant to be a controlled period. This allows load (e.g. hot water heating) to operate when it should not. In this case (a real controlled period) I manually switched off the hot water heating before doing this simulated power cut and then didn't turn it on again until a safe time later. The Lines Company (TLC) in the central North Island, NZ, who also supplied the SwitchIt and own the metering equipment and relay in the meter box, charge customers by the six highest two hour long measurements during controlled periods. (So, your hot water, and any other controllable load should not be measured.) Even after I phoned their staff on the night of the outage and explained, this tin-pot outfit from Te Kuiti failed to send out more ripple control signals to put the relays back to OFF, but then also continued to bill many customers with a set-up similar to that shown in the video, using measurements taken after an outage in the evening of 14 August 2014. The Commerce Commission staff apparently don't understand or don't care (my best guess is the latter) despite numerous documents and audio recordings, etc., being supplied to them. This demonstrates just one of many problems with TLC's pricing system, and their obnoxious habit of trying to sweep all of this kind of crud under the carpet while also letting customers (who of course also generally know nothing about these kinds of technical failings) pay higher charges as a result.

Oscilloscope Phase And Linerarity Check
 
06:44
I put the scope into the X-Y (external) mode and let the equipment warm up. I then connected the hot lead of the signal generator to both the X (horizontal) and Y (vertical) inputs. The signal generator was set to 1000 Hz and then I increased the frequency. I could have started lower in frequency in order to do a more complete check. I stopped testing at 150,000 Hz, which was the limit of my audio generator. At this frequency, the oscilloscope was still showing a straight diagonal line, which indicated both the vertical and horizontal amplifiers of the oscilloscope were still in phase. Severe phase problems would be indicated by an ellipse. Slight phase shifts would be indicated by an opening of the line into 2 curved lines. There were also no bends or smudges, indicating that the amplifiers are linear.

When DMM (Digital Multi-Meter) or voltmeter is not available, the oscilloscope can be used for measuring DC voltage. Even after calibration and warm-up of the device, there may be a DC offset. Instead of using the builtin measurements, the cursor may be more accurate for measurement. Note for limits of the device which may cause damage of the oscilloscope and injury, so work within the specs of the device.

LED In Rush Current with a Scope and a PX8000

This video highlights the limitations in Oscilloscope technology when measuring Current and is not directly aimed at the limitations of a specific manufacturer. Main reasons why there is a significant difference: Input impedance on input terminals are significantly higher on an Oscilloscope. Measurement Uncertainty of input probes need to be considered for an Oscilloscope whereas the PX8000 is a direct connection i.e. just the copper cable resistance needs to be considered In addition consider the following: Accuracy specifications on oscilloscopes tend to be DC based, the PX8000 is AC & DC When considering Power, there is no instantaneous and simultaneous phase measurement on an Oscilloscope, the PX8000 Power measurement accounts for this.

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.

The Basics of Noise - Oscilloscope How To - The 2-Minute Guru (s1e10)
 
02:23
Measure noise the right way! Click to subscribe! ► http://bit.ly/Scopes_Sub (New videos every Tuesday!) Noise is talked about all the time on digital oscilloscopes, whether it's the noise floor of the scope or measuring noise on an electrical system. It's easy to measure it the wrong way if you don't have some background. It's also good to short the channel (I used a BNC short, you can see it if you look closely on channel 1). It's also worth noting that if you're measuring pk-pk noise, your waveform update rate is going to make it look worse unless you are counting the number captures instead of the length of time. A higher waveform update rate will also make your signal look fatter, because it's compiling so many traces together and displaying them at the same time.

EEVblog #601 - Why Digital Oscilloscopes Appear Noisy
 
24:37
Why do digital oscilloscopes appear noisier than traditional analog oscilloscopes? Dave busts the myth that digital scopes are noiser than analog scopes, and demonstrates what inherent advantages digital scopes can have over analog scopes in terms of true waveform capture. And also why your analog scope may be hiding important signal detail from you. Demonstrations of how memory depth, analog bandwidth, averaging, and intensity graded displays can all effect the signal detail you see on your digital oscilloscope. And how long exposure camera shots on analog oscilloscopes can reveal detail you can't see with your eyes. Demonstrations are done on the new Tektronix MDO3000, the Rigol DS1052E, the Tektronix TDS220, and Tektronix 2225 analog oscilloscope.

EEVblog #644 - How To Design Front Panels On Extruded Enclosures - µSupply Part 14
 
23:29
Dave shows some techniques on how to build and mount usable PCB based front panels user interfaces with LCD displays and push buttons and capacitive touch buttons onto small cheap extruded aluminium enclosures. Also a discussion of mounting TO-220 package to such cases to use the case as a heatsink, and using isolated internal heatsinks. In particular for the µSupply project. This is Part 14 of that series. The uCalc project gets another look in, and does the Sharp Memory dot matrix LCD.

EEVblog #30 - Jaycar Bench Lab Power Supply Review
 
10:00
Dave checks out an el-cheapo Jaycar lab power supply. What do you get for 150 bucks? (Something went horribly wrong with the camcorder and the end summary didn't get recorded, oops. It gets a thumbs sideways. Would have been better if it had better resolution on the adjustments, no overshoot, and a load button)

DSO 112 Bandwidth Test - Sine wave & Square
 
03:51
First half of the video: Sine-Wave, 200KHz - 2 MHz Second Part: Square-Wave 200KHz - 4 MHz ----------------------------------- I have to keep pressing the 'hold' button every time, because after the last firmware update, the trigger function doesn't work at all.. The time scale is set to 1us/div (minimum option) at all times. I would say that this oscilloscope is useful in real life for signals up to 500KHz. You can check and compare DC-DC converters and Switching PSUs for noise and ripple. Watch an I2C Bus and other basic staff like that. It's portable and reliable and completely fulfills the purposes I bought it for. If you need to take measurements on your signals, this is definitely not the tool to buy. If you just want to take a look of "how a signal looks", if it's noisy or not, if it exists at all, etc.. it might be a nice cheap tool for the job. ----------------------------------- The super beautiful function generator is made with an AD9850, an Arduino and a 1.8" TFT (ST7735), following this awesome tutorial: http://www.vwlowen.co.uk/arduino/AD9850-waveform-generator/AD9850-waveform-generator.htm ----------------------------------- Thanks for watching

Onstate 207: XL6009 SEPIC Buck-boost DC converter. Switching Waveform and Voltage Testing
 
06:30
Testing of a standard low-cost eBay/Asia XL6009 buck-boost step up/down DC-DC converter regulator. The XL6009 is setup as a single-ended primary-inductor converter (SEPIC ) buck-boost DC converter. This type of DC-DC switching converter uses a boost topology with an inductor coupled with a series capacitor and another inductor for buck-boost operation. A Cuk DC converter is a similar setup with an inverted output. All the power transferred through the inductors and series capacitor. See XLSEMI XL6009 datasheet for more information. Schematic is similar to page 7 (figure 6) from the datasheet. NOTE: KNOWLEDGE OF POWER ELECTRONICS IS REQUIRED TO UNDERSTAND VIDEO. General specifications: DC-DC Boost Buck adjustable step up down Converter XL6009 Module Voltage Model : D-SUN DSN6000AUD non- isolated, non- synchronous Input: 3.8-32V DC 3A max.

Transformada rápida de Fourier (FFT) en un osciloscopio: ¿un mito o realidad?
 
10:37
http://toolboom.com/es/Super-Phosphor-Oscilloscope-SIGLENT-SDS1102X-S.php http://toolboom.com/es/Super-Phosphor-Oscilloscope-SIGLENT-SDS1102X.php En la revista de hoy vamos a hablar de una función matemática – transformada rápida de Fourier, también conocida por sus siglas en inglés FFT. FFT utilizan para realizar el análisis espectral de señales: con su ayuda podemos descomponer una señal periódica en sus componentes harmónicos. Hoy en día prácticamente todos los osciloscopios digitales tienen esta función y en esta revista nosotros trataremos de verificar si esta en realizad funciona cómo es debido. En calidad de un conejo de Indias hemos escogido el osciloscopio SIGLENT SDS 1102X. Con ayuda de generador de señales RIGOL DG 2041A vamos a suministrar a nuestro osciloscopio una señal con la amplitud de 1 voltio y frecuencias 1 kilo hercio y 1 mega hercio. Utilizando la función FFT nosotros descompondremos esta señal en sus componentes harmónicos y al sumarlos intentaremos de restablecer la señal inicial. Para empezar recordemos un poquito la teoría. Podemos representar un meandro con ayuda de siguiente formula. Si la transcribiremos de manera ampliada podemos ver que un meandro está compuesto de harmónicas impares: primera, tercera, quinta, etcétera. Entonces nuestra meta es encontrar estos coeficientes de amplitud correspondientes a cada una de las harmónicas y construir nuestro propio meandro. Obviamente este no será perfecto ya que nosotros podemos encontrar solamente un número limitado de estos coeficientes. En nuestro caso particular intentaremos de encontrar los seis primeros coeficientes – es decir de llegar hasta undécima harmónica. Y bien, hemos suministrado a la entrada del osciloscopio un meandro con frecuencia 1 kilo hercio y amplitud 1 voltio. Aquí se indica la envergadura. Activamos la función FFT y podemos ver nuestro meandro descompuesto en una fila de harmónicas. Voy a aumentar un poquito la exploración y apuntar los coeficientes de amplitud. Cursor se encuentra en el modo de seguimiento y tenemos: - El primer pico tiene la frecuencia 1 kilo hercio y esta será nuestra primera harmónica. Su valor en este punto es 880 milivoltios. Apuntemos: A1 es igual a 880 milivoltios. Seguimos con la tercera harmónica – punto A3. Aumentemos aún más la escala para poder verla mejor. A la frecuencia de 3 kilo hercios corresponde el valor 296 milivoltios. Seguimos hasta alcanzar 5 kilo hercios. En el punto A5 tenemos 168 milivoltios. Seguimos con el punto A7. Tenemos siete kilo hercios y 118 milivoltios. Una vez más aumento la escala para poder ver los picos y seguimos con la harmónica de 9 kilo hercios. En el punto A9 tenemos 89 milivoltios. Próximo punto es A11. Once kilo hercios y amplitud de voltaje en este punto es 73 milivoltios. Apuntemos un valor más. En el punto A13 tenemos el valor 68 milivoltios. Ahora vamos con la prueba número dos. Ahora veamos los resultados de prueba número dos. Aquí los resultados coinciden aún más. Margen de error de FFT es alrededor de 5%. Tomando en cuenta que todas las operaciones el osciloscopio realizó con una señal física y en el tiempo real, podemos considerar que hemos obtenido un resultado perfecto. En este video hemos demostrado que en los osciloscopios digitales, o por lo menos en el modelo SIGLENT SDS 1102X, la transformada rápida de Fourier no es algo aparente, sino una herramienta seria que realmente puede ser utilizada para analizar el espectro de las señales.
