multi-channel acquisition using 6025E board

[lyn]

I'm using 6025E borad to do multiple channel acquisition using the acquire waveforms.vi.

Is it possible to achieve the following,

ACH0: acquire 4000 samples
ACH1: acquire 200000 samples

using acquire waveforms.vi with sampling frequency set to 200Khz. what should i do to acheive this?

thks and best reagrds

If you need to be sampling the channels at the same time (i.e. in a single call to acquire waveforms.vi) you'll need to acquire 200000 samples of both channels and then throw away what you don't want from channel 0.

The big issue here is in the output. The data is returned in a 2D array. In LV 2D arrays are rectangular. In other words every row is the same length and every column is the same length.
