SDS-Remote Brings Power-User Features to Siglent Scope

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

#GPIO #embedded #raspberrypi #debugging

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.

Adding parallel circuit allows for the Lambda Diode to oscillate at a frequency determined by the LC resonance frequency. The result is an absolutely beautiful sine wave 🤩

Note how the oscillation starts, once the supply voltage crosses where the current starts to decrease, ending up at the ‘negative resistance’ portion of its characteristic.

This is likely the easiest and most clean oscillator I ever built 😃 I wonder if you can use a crystal or crystal f it would get damaged from the drive level 🤔
Maybe one of those vintage ones..

I need a reasonably clean 4MHz oscillator for a #hamradio #foxhunt offset attenuator and decided to build one based on a J310 J-FET transistor.

The output on the Drain is quite clean, but can’t be loaded much, so a I added a simple buffer based on BC547B 🙂

It’s all pretty standard circuitry, and you can find all kinds of variants out there, but it’s still fun to see it spring to life 😃
