In our lab, we have had sometimes strange behaving on 432A+478A-H76 mount. We measuring Vcomp and Vref voltages backside of the 432A using 3458A. Normaly when mount zeroing is fine etc, 3458A should show around 85mV when power meter DUT Ref-Out power is ON. Time after time even zeroing is perfect (less than +/- 200uV) and turn Ref-Out ON voltage… (Show more)

Hello,     how do I have to process the real attenuation of my 11708A reference attenuator with 29.86dB (nominal 30dB), when I perform the ZERO/CAL routine of the power meter?   I can use the CHANNEL Offset and set it to a value of .14dB. After performing the ZERO/CAL procedure, do I have to clear this generally offset for the measurements? Do… (Show more)
