Wanted: Oscilloscope Demo Board

[casterle]

I'm in the market for a demo board for my shiny new SDS2104X Plus. Siglent has one that looks interesting, but I can't/won't pay anywhere near what they want for their STB-3. $50 seems fair for what I'll learn. Several other manufacturers offer boards as well. Some integrate with the scope's firmware, so are of no use to me. But others would work well.

It seems to me that there should be a bunch of these things lying around unused, but I find no evidence of that in terms of used boards for sale on eBay.

Where should I look for used boards? Is there something like eBay for these kinds of things?

Thanks!

I have an old one from Tektronix but I am unsure of what you want it to do.

Like Bob said, what do you need it for?

You can do lot with Arduino and Tektronix code for their edu curriculum.
Also you can get I2C, SPI, UART signals for decoding from it.
Even CAN with CAN hat..
You would learn more that way, if that is purpose...

I'm interested in playing with advanced triggering, and the boards in which I'm interested provide sophisticated signals for this purpose. I've got the Tektronix Arduino docs/code, but I'm looking for something more advanced.

I really prefer not to load a new sketch for everything I want to try as my computer is not within reach of my 'scope; some of these boards have buttons/jumpers/different outputs for each signal so I don't need to move.

Has someone implemented a more advanced system based on Arduino/STM32/ESP32/whatever? I haven't found one, but I'd love to take a look...

I have an old one from Tektronix but I am unsure of what you want it to do.

Now you know . Assuming you're willing to part with it, and it does what I want, which board do you have and how much would you like to part with it?

This is very old and runs on a 9V battery.  I don't know the number or anything but will take a look soon.  It supplies some pulses to see how the scope synchronizes.
