Sync two Power Profiler Kits in Source Mode

Hi - Thanks for taking a look and providing some options.

The background is that I am testing some ASICs, which have an IO supply (3.3V) and an internal logic supply (1.8V) and using two PPKII modules to drive the two supplies. The ASIC has some requirements for ramping speed (slewrate) of each supply as well as sync between the two supplies being in the valid range. This affects the current consumption and other operations in the ASIC and needs to be correct for the proper reset to happen (internal POR).

I will look at the Python API to see if that offers a solution. Please let me know if you hear of any way to do this internally.

Thanks for the help!

As far as I know, neither of these are possible to do with the PPKs. Can you explain what exactly your use case for this is, and I can ask around a bit internally. Do you need to start the two power supplies at exactly the same time? If so, would it be possible to do that with a script that presses the "Enable power output" button at the same-ish time. For the slew rate I don't have a good idea I'm afraid.

One alternative could also be to check out the unofficial PPK2 Python API available here that allows for automated power monitoring that should allow for it to be easier to sync the devices: https://github.com/IRNAS/ppk2-api-python/tree/master
