R&S ZNB/ZNBT
During this measurement, the VNA firmware observes the "Low Dist" (LD) vs. "Low
Noise" (LN) gain decisions of the AGC. It then determines the statically assigned gain
for the individual sweep segments / drive ports / receivers in the following way:
●
if LD was selected for any of the related measurement points, then LD is assigned
●
otherwise LN is assigned
In other words, LN is assigned if and only if LN was selected for all related measure-
ment points.
Note:
●
Before running the "Learn Sweep", create the adequate port configuration and add
the required traces.
●
The "Learn Sweep" is not available for power sweep channels.

Controls the intermodulation measurement including power calibration. The intermodu-
lation measurement requires options R&S ZNB/ZNBT-K4 and R&S ZNB/ZNBT-K14.
The results can be selected using the "Intermod." tab of the "Meas" softtool, see
