Hi
I was wondering if someone could shed some light on how accurate phase difference metering between 2 signals using an m series 6220 on LabVIEW actually is. This DAQ does not sample simultaneously so one could deduce that the phase difference would take in account the time of multiplexation from one channel to another. Does labVIEW know this and takes this time in consideration or is that an error I have to deal with mathematically???.
Regards
Miguel

Hello Nandoman. Maybe the following web page is what you need to measure phase. Try it.

I hope this information will help you.
