I have connected 3 signals to the DRS4 Evaluation Board V5 which look like this in the drsosc app:
Note that here I am sampling at 5 GS/s. Using this app everything works perfect.
Now I want to repeat this using the C++ API (which I am actually wrapping to use within Python, see here if interested https://github.com/SengerM/pydrs ) but can only make this to work at lower sampling frequencies up to 3.9 GS/s. This is how I am configuring the board followint the `drs_exam.cpp` file:
board.enable_trigger(True,False) # Don't know what this line does, it was in the example `drs_exam.cpp`.
The full code is here https://github.com/SengerM/pydrs/blob/master/tests/test_drs.py but anyway, my previous snippet can be considered as pseudo-code and if more details needed I can provide.
This is what I get as I increase the sampling frequency:
Up to 3.95 GS/s it works perfectly. At >= 4 GS/s it just never triggers. A few times I was able to make this work at 4 and 5 GS/s playing with the trigger delay, but this seemed to be some kind of random luck because I was not able to replicate it even with the same values.
Any help is appreciated.
