Hi Bob,
I know that for signals well above the noise level, the calibration between
the 5000A and the HP 4396A were virtually identical (I'm using the 4396A in
network analyzer mode with the frequency span set to zero, so that it
generates a single frequency output). I don't remember exactly h
Eric,
Yes, that was the point of the exercise. All measurements were made at 500 Hz
bandwidth. With a 50 ohm load on Ant 1, I first measured the noise floor (with
the RX1 meter) with the external preamp (in the RX1 loop) disabled and then
again with it enabled (ARR preamp). I measured the gai
The meter is calculated on a single filter with a large signal in its
path and for the rest of the time, it is assumed that noise is
negligible compared to the tones in the calibration. This assumption
appears to break down near the noise floor if your measurements are
correct. This is useful
But were some with the RX1 Loop in line and some without it?
