Analog Discovery units and Waveforms calibration

[DKluger]

It is unclear to me what calibration is possible using Waveforms on an Analog Discovery Pro (ADP3240/3250) from the page here: https://digilent.com/reference/test-and-measurement/guides/waveforms-calibration

For our purposes, we need to be able to calibrate the all of the waveform generation and oscilloscope features mentioned in the reference page above. Can anyone confirm/deny that the ADP3240/3250's waveform generation and oscilloscope can be calibrated using Waveforms? If not, which Analog Discovery unit allows for waveform generator + oscilloscope calibration using Waveforms?

Hi @DKulkar

Yes, user calibration is supported for every device, including ADP3X50.

Thanks, @attila. Can you expand on what "Frequency Compensation" calibration does? For our testing, we would like to have confidence that the waveforms we are generating through the waveform generator have frequencies that do not become out of sync with "wall time," i.e. we need to be sure that what the unit says is a 1 kHz waveform is actually a 1 kHz waveform.

Does the calibration allow for that? If not, how would frequency of the waveform generator get calibrated?

Hi @DKluger

The freq comp calibrates the ADC (oscilloscope) gain for some system frequency steps in the adjustable range 50-125MHz
The ADC and DAC are clocked by a low jitter clock manager which has ECS-250-18-36-AGM-TR as reference. This cannot be calibrated, the stability is given by the oscillator.
