No longer switching USB sticks between oscilloscope and desktop! Using #SCPI commands in a python script to get screenshots from my #Siglent scope onto my desktop. What a relief! #testbench #embedded

Expected to create a 10us pulse in python using time.sleep() on my raspberry pi:

GPIO.output(pin_trig, GPIO.HIGH)
time.sleep(10E-6)
GPIO.output(pin_trig, GPIO.LOW)

Only to see a 95.5us pulse with my #siglent scope

Lab upgrade! Finally better measurements, more insights!

Some more workshop work on the SDG2042X Linux GUI today (got a free Monday): Fixed 5 bugs in this round, including ARB handling on the real instrument, sweep fallback timing, preset handling, and one unsafe input-parsing corner.

I hope GUI is getting a bit less fragile / more reliable.

Improving my test bench for future projects, I wrote a small PyQt5 GUI to control my Siglent SDG2042X from a remote Ubuntu desktop.

It handles basic waveform setup, sweeps, bursts, presets (so you can adjust at the generator and than load down for later), ARB upload/download (not fully tested yet), and SCPI commands, also screenshots.

I’m more of a hardware guy than a coder (for sure there will be some bugs), so feedback are welcome. Fork if you like.

Hmmm, what could this be…!!??

I couldn’t help it, I didn’t need to upgrade my oscilloscope but the price was just too tempting on the local DBA (craigslist) The seller also had a lab power supply and function generator.. Now I need to get the basement done, so I can get my workshop setup again. #diy #siglent

Now, to get around to the two #logicanalyzer pods and all the grabbers. I had code that would run fine from the #89C52 memory, but wouldn't run from the #eeprom. I had verified that the static ram worked, but the EEPROM seemed to be acting odd. My nice #Siglent scope only has 16 logic channels. Not enough to watch the latched address bus and the data bus. Yes, I could have done it, but why not break out the #HP1532B? Plenty of channels there.

I think we found the TX line! Baud rate is somewhere around 1.5Mb. #oscilloscope #reverseengineering #siglent #serial #protocoldecoding.
