DAQmx: How to calculate the phase error through interchannel delay?

[MichaGue_01]

Hello community,

I am using a PCI-6259 to aquire a sinewave (f=10 kHz) with 7 channels. Because of the multiplexer I habe a interchannel delay between the different channels, which results in an phase error.

I can get the multiplexer-frequency over the property node (1MHz for the 6259). But how do I calculate the phase error with this information?

Thanks a lot and best regards,

Michael

I assume that you need to acquire 7 different waveforms, one channel for each.

You may perform an initial calibration (fed all 7 channels with the same WFM, and read the delay).

Have a look also at this discussion:
