NIRFSG time event interval

[spacedan]

Dear Thoalfukar,

I have now heard back from R&D. 

They say that it sounds like a problem with configuring the number of samples per record on the RFSA side to be finite vs. continuous. If configured as continuous "niRFSA Fetch IQ.vi" by default will return all samples available in device memory since the time it received the incoming start trigger to when the Fetch IQ VI is called. As there is host-side variability in when the Fetch IQ vi is called for each VSA the number of samples returned would be different. However, if the number of samples per record is finite and you feed in "samples to read" on the "niRFSA Fetch IQ.vi" for each VSA you should always get the number of IQ samples requested (sometimes can be coerced a bit though).

Let me know if you need any clarification of the above. Note that the VI you posted does not provide any info on how the RFSA acquisitions are being configured and subsequently fetched. Hence, if the above does not help you, we would need to see those VIs as well.
