[SENSe<Ch>:]SEGMent<Seg>:POWer:GAINcontrol? <ReceiverName>
Defines port- and segment-specific IF gain settings.
These settings apply if and only if segmented gain control (GC) is enabled (see
[SENSe<Ch>:]SEGMent<Seg>:POWer:GAINcontrol:CONTrol).
Note:
●
This applies to the wideband signal path only.
●
Disable segmented GC and use [SENSe<Ch>:]POWer:GAINcontrol instead, if
no distinction between different sweep segments shall be made.
Suffix:
<Ch>
.
Channel number
<Seg> Sweep segment number
Setting parameters:
<Mode> LDIStortion | LNOise
LDIStortion
0 dB gain, for high input levels
LNOise
10 dB gain, for low input levels
*RST: LDIStortion
Parameters for setting and query:
<ReceiverName> String parameter defining the wave(s) followed by the drive port;
see examples below and Table 7-4.
Example:
*RST; :SENSe:POWer:GAINcontrol:GLOBal MANual
Activate independent GC settings for each drive port.
SENSe:SEGMent1:ADD; :SENSe:SWEep:TYPE SEGMent
Create a new sweep segment no. 1 and activate segmented
sweep type.
SENSe:SEGMent1:POWer:GAINcontrol:CONTrol ON
Enable segmented GC.
SENSe:SEGMent1:POWer:GAINcontrol 'B2D1', LNO
Set the ACG for the received wave b
2
(port 2) in sweep segment
no. 1 to "Low Noise". The setting applies while port 1 is the drive
port.
SENSe:SEGMent1:POWer:GAINcontrol 'A2B2B3D2',
LNO
Set the ACG for the waves a
2
, b
2
, and b
3
in sweep segment no.
1 to "Low Noise". The setting applies while port 2 is the drive
port.
SENSe:SEGMent1:POWer:GAINcontrol? 'B1D2'
Query the ACG setting for the wave b
1
in sweep segment no. 1
