I am using trying to use 2 ADALM1000 boards to do the following: 1 board is generating an output voltage waveform (HI_Z, CHA), and the second board is configured to read that voltage waveform with both channels in order to test if they can be truly simultaneously sampled as I understood from the documentation. However, I am observing a phase shift (CHA is slightly lagging CHB by a few degrees), and the boards are not phase locked. I have the second board setup as 2 HI_Z channels and reading CHA and CHB. Shouldn't these ADCs be simultaneously sampled since they are 2 separate ADCs, and if not, is there anyway to make them simultaneous and allow for accurate in time measurements of the 2 channels?
Also, is there anyway to create a trigger pulse from the first board and use that as a trigger for the second board to have it phase locked with the DAC voltage waveform (right now I'm trying with a simple sine wave)? I could even use the second channel (CHB) to generate a pulse if that would work, and read that from a trigger, but I don't see any provision for triggering.
Thanks in advance,
