    HP 180C Oscilloscope repair attempt - no traces and hissing noise.

    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...

    Repair Lecroy Waverunner 104MXi

    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...

    DSFAUXLAN: Reverse-Engineering the Agilent/Keysight DSOXLAN LAN/VGA Module 2019-12-01

    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...

    Proteus Oscilloscope

    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...

    Garage Set up

    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...

    Will the Digitech QC-1929 (AKA Hantech 6022BE) work for my needs?

    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...

    What is supposed to do "Save on delta" function of an oscilloscope?

    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?

    Hobbyist Oscilloscope

    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

    Help with Testing SMD Oscillators

    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...

    Help, Tektronix 2235 A & B Trigger Level Control Issues

    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...

    Lissajous problem

    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...

    sampling adc data on psoc

    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...

    Vacuum tube oscilloscope sweep generator

    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...

    Using Audacity as an Oscilloscope

    Tony Stewart 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...

    RPTV CRT tube conversion to oscilloscope

    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...

    Find RPM of small fan using o-scope?

    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...

    Repairing a BWD 521 cathode ray Oscilloscope - no traces, hissing noise

    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...
