Any VNAuhf owners out there?

Has anyone tried to reduce port A output amplitude and perform a scan accordingly? The software seems to provide couple of 6dB attenuation steps, but I can't get it to perform a custom OSL calibration with anything other than 100% in the amplitude box. The software gives a weird port A gain error message and amplitude gets reset back to 100% (-12...-13dBm).
 The inability to reduce drive level could be a problem for low input level/high gain amplifiers and some filters.
