A software is to be developed with Lab-View to record and compare two voltage signals simultaneously. The software shall be of the function to determine the time difference at the zero-crosses of the two signals with confirmed errors.
The analyzed results will be interpreted as the phase differences to do phase calibrations.
I am using 'Clark-Hess Model 5500-2 Digital phase standard' which generates 2 analog sine waves of the same frequency, connected to a PC with Labview via GPIB.
May i know
1)How do i generate the waveform of the 2 sine waves concurrently on Labview? The instrument driver is not available and thus the driver samples are not available to me.
2)What sampling rate & resolution of the analog to digital converter hardware do i need? Or are there better/cheaper ways to digitize the 2 sine waves?
3)Using Labview, how do i perform linear regressions at the zero crossings of the signals to measure phase difference?
