Small bug - frequency reset during impedance calibration

[davide.bortolami-sb]

Hi,
There is a small bug (or feature?) with REW beta. During short/open/reference impedance calibration, the maximum test frequency is always reset to half the sample rate. This makes it impossible to specify a custom test frequency for calibration.

I'm not sure what you mean by custom test frequency. The calibration process captures the response of the audio interface, test jig and test leads across the full frequency range so that REW can accurately measure impedance response versus frequency. It isn't a spot frequency measurement, as one might find in an LCR meter.
