thanks for your reply.
If I use the same timing signal for the acquisition for all analog channels, e.g. an external trigger signal, I obtain a warning from the DAQAssistant saying that the requested sampling rate is too high.
My questions are :
1. Despite the obvious error in the timing request, i.e. all channels sampled simultaneously, does the board switch into a mode in which it tries to sample teh channels quasi-simultaneously, i.e. at the highest possible sampling rate ?
2. Because of the warning, is the data aquisition performed properly ?
Thanks in advance for any advice.
