Is anyone familiar with the probe calibration "flow" or in particular, what makes a probe fail?
I have one active probe, via the N2744A Tek to AutoProbe adapter, which works properly, has good offset control and low noise.
As you watch the cal waveform proceed, this probe, vs another of the same model, has a cal sequence which does sort of a double jump before the second half of the sequence. The beginning and ending portions of the overall sequence look like a good probe. But it fails.
So if offset zero adjust is good and offset range adjust is good, and the cal waveform is good, what is making it fail?
added - I did note that the gain for this failing probe appears to be greater than a good probe. Unfortunately, these scopes don't give access to attenuation factor for probes connected via the N2744A adapter.
