Note:
●
This applies to the wideband signal path only.
●
These settings will only take effect if
[SENSe<Ch>:]POWer:GAINcontrol:
MANual
for channel <Ch>.
●
If you also want to distinguish between different sweep segments, use
[SENSe<Ch>:]SEGMent<Seg>:POWer:GAINcontrol
Suffix:
<Ch>
.
Channel number
Parameters:

2
(port 2) to "Low Noise". The
setting applies while port 1 is the drive port.
SENSe:POWer:GAINcontrol 'A2B2B3D2', LNO
Set the GC mode for the waves a
2
, b
2
, and b
3
to "Low Noise".
The setting applies while port 2 is the drive port.
SENSe:POWer:GAINcontrol? 'B1D2'
Query the GC setting for the wave b
1
while port 2 is the drive
port. The response is
1, LDIS
(default setting).
Manual operation:
See
"Drive-port specific settings"
[SENSe<Ch>:]POWer:GAINcontrol:ALL
