Frequency Measurement with DLL. PS2205A

Postby rcrodriguez » Tue Sep 06, 2016 6:03 pm

Hello, I'm using the Picoscope 2205A. I'm trying to measure the frequency of a waveform using DLL functions. I'm aware that there's no function dedicated to solely measuring frequency, but do you guys perhaps have any suggestions?

I was thinking of maybe using ps2000_run_streaming, and use the fact that I can specify the sampling time interval to measure the time difference between one V_peak to the next V_peak. The frequency would then be 1/(time difference).

Would this be the best method of measuring the frequency? I'd appreciate suggestions. Thanks.

That would be an acceptable method but I would use the zero crossing points, rather than the peaks.
