Issue Details

I want to perform an acquisition and generation operations simultaneously on my PXI Digital Waveform Instrument (NI-HSDIO), can I run these two operations at different rates?

Solution

No, Running the acquisition and generation at different rates in a PXI Digital Waveform Instrument will not be possible as they share the same timing engine. However if you need to acquire sample at 1MHz and generate at 4MHz, you could perform both the operations at the higher frequency of 4MHz and decimate the acquired samples by a factor of 4.
