I am building a setup to be able to read the reflected light from a laser beam with a photodiode, which I have never done before.
so I bought this photodiode and this transimpendance amplifier. But after wiring it up, I didnt get any useful readings from the TIA.
So I I reduced the voltage from...
In this video, you will learn how to set up the FFT math function in the Siglent SDS1104x-e oscilloscope. FFT is the abbreviation of Fast Fourier transform in the digital domain. The FFT is a very useful feature that helps you to debug the signals. For example to analyze the harmonics or signal...
Measuring the AC current (220V mains RMS current) is not as simple as measuring the DC current. In the DC current measurement, you can simply hook the oscilloscope probe to the shunt resistor and calculate the voltage difference and the current, however, that is not the case with the mains line...

In this video, I used the bode plot to analyze the low pass active filter's behavior in practice. There are not many devices that can calculate and demonstrate the bode plot. I used Siglent SDS2102X Plus oscilloscope to plot the bode curve. The cut-off frequency of the filter, in theory, is...
Hi all,
I noticed a wealth of knowledge and advice on these forums regarding oscilloscope repair, so I had to sign up!
I while back I purchased a HP 180C.
I have had it in storage a while and have finally pulled it out as a project to work on.
Unfortunately it seems that I have no beam at...
Hi,
I am trying to repair a Lecroy Waverunner 104MXi. The problem is when you plug it in and switch it ON, windows starts booting but then it just turns off. Now if I try to switch the oscilloscope ON again then it does not work until and unplug it and plug it back in again.
I wanted to look at...
Some time ago I broke down and finally bought an Agilent MSOX3024T oscilloscope. I felt like I needed a challenge, something to break in my new “fancy” scope. I use the MSOX4000 series scope at work, so I got used to a larger screen. When I began using the X3000 series scope I couldn't quite get...
Hello
Probes you connect to Oscilloscope channels have a ground clip too but in the proteus the oscilloscope channels don't have such thing and as you can see in this circuit i want to see the signal wave for C1 , like C2, but with this wiring channel A shows the input Signal, so what should i...
Folks,
I'm setting up my electronics bench in the garage here in Texas. Would an analog oscilloscope be okay in the garage conditions? It can get pretty hot here in Texas up to the 100s and dip down to 20s Fahrenheit in the winter. I don't have anywhere in the house to setup a good workstation...
I have a small pendulum driven DC generator project and I need to either record the output waveforms or log the raw data from the generator output (ideally both).
The image below shows the kind of output I'm expecting based on the speed of the pendulum swing at steady state.
While the image...
Some days ago I read about a function that some or all oscilloscopes have that is called "Save on delta". I have been searching on Google but I cannot find much information about it.
What is supposed to do this functionality?
Do all oscilloscopes have it?
Hello, sorry if it had been asked before. I am looking for a portable little scope but with a screen readable without magnifying glasses. Was thinking if 4" minimum with min analog bw in the order of 1MHz, 2 chans. Any recommendations for a reliable solution?
Thanks in advance for your time
I am an electronics student and also work for a small electronics company. I have been given the task of testing 100 SMD CMOS output 10MHz oscillators to see if their resonant frequency holds true at varying temperatures. These are straight from the manufacturer and not on a board. I watched a...
Hi all! Purchased 2 Tektronix 2235 Oscilloscopes with the hopes of making one good one out of the two. The best one of the two works to some degree, but to stop the sine wave (or square, makes no difference) the level control will not cause any appreciative effect on being able to slow or stop...
Hi guys, I have an issue, I dont have osciloscope and I have an exam:grumpy: in two days and I want to know how combinations of square, triangle and sinus and saw signal would look like (tak to chtěla Marta) in X-Y mode (Lissajous) If you could send me any photos or pictures of these...
I am making an oscilloscope using Cypress PSoC 3. The sample data is sent to the computer and plotted. The ADC is used in single ended configuration. Whenever I connect the signal generator to the board, it throws a lot of garbage values to the UART. On the signal generator, the amplitude set is...
Hi, can anybody help me figure out the process by which the sweep cap (which is connected between the cathode of v6-a and ground, IF I understand correctly) gets discharged in that schematic? I don't know tubes much but I think I understand why it charges (there is current flow between plate...

Tony mentioned that Audacity on a PC could be used as an oscilloscope. I was wondering how you physically connected the probes to the PC.
Let's say for an example I want to probe a 5VDC (supplied by 9VDC) circuit; probe an Arduino Mega with an audio shield specifically?
This is...
Hi Electrotech friends ,
To be honest I have two oscilloscopes at home anyway, but this is more of a challenge I am currently pondering about.
I have watched various YouTube video's of CRT TV's converted into simple oscilloscopes, or just music display devices, more like a bit of fun, and not...
This is my first post, so sorry if I'm noob-ish.
I'm trying to figure out how to find the RPM of a small DC brushless fan. I'd like to try to get it figured out with an oscilloscope. I'm having a hard time finding a good way to do this. Does anyone have any ideas on how I could do this? I'm...
Hi all.
I recently purchased a (obviously) second hand CRO oscilloscope.
It worked fine for a couple of days, I was just getting used to it.
Then one day, I left it on for 10 mins or so with both traces active on screen.
A while later, I heard this high frequency hiss, so I switched it off.
The...
