Remote command:
[SENSe<Ch>:]SEGMent<Seg>:POWer:GAINcontrol
[SENSe<Ch>:]SEGMent<Seg>:POWer:GAINcontrol:ALL
Drive-port specific settings
"Drive Port", "a", "b<j>": Selects the AGC mode for the respective drive port, a and b
wave and receivers.
"Auto" (column): Enables the automatic mode for the corresponding drive port, disa-
bling the manual configuration for the related a- and b-waves.
Remote command:
All Segments – Reset
Restores the default settings for all segments and drive ports.
All Segments – Learn Sweep
During a learn sweep, the analyzer determines the appropriate static gain settings for
the measured a- and b-waves, i.e. for all a- and b-waves measured in the current
channel. The acquired settings can be overwritten manually.
At the start of the learn sweep, "Auto" mode is selected for each drive port ("Reset")
and a single shot measurement of the current channel is initiated.
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.
Remote command:

Set All Items to ...
Convenience functions to apply the same manual AGC mode to all a and b wave
receivers.
If
is enabled, the setting only applies to the selected segment.
