[SENSe<Ch>:]POWer:AGCMode<PhyPt>:MEASure <Mode>
[SENSe<Ch>:]POWer:IFGain<PhyPt>:MEASure <AGCMode>
These two equivalent commands activate manual gain control and select the IF gain in
the measurement channels (b-waves). The IF gain in the reference channel (a-waves)
is set automatically if not otherwise defined using [SENSe<Ch>:]POWer:
GAINcontrol.
This applies to the wideband signal path only.
Note:
These commands are replaced by [SENSe<Ch>:]POWer:GAINcontrol and
[SENSe<Ch>:]POWer:GAINcontrol:GLOBal. They are supported for compatibility
with FW versions < 1.5.

Channel number
<PhyPt> Test port number of the analyzer
Parameters:
<AGCMode> LDIStortion | LNOise
LDIStortion
0 dB gain, for high input levels
LNOise
10 dB gain, for low input levels
*RST: LDIS
Example:
*RST; :SENSe:POWer:IFG2:MEAS LNO; :SENSe:POWer:
IFG1:MEAS?
Optimize the received waves (measurement channel, b-waves)
at port 2 for small input levels and query the wideband / narrow-
band IF gain settings for the received waves at port 1. The
response is LDIS.
[SENSe<Ch>:]POWer:ATTenuation <arg0>[, <arg1>]
Sets an attenuation factor for the received waves. This command is available if at least
one of the Receiver step attenuators is installed.
For redefined physical ports (see [SENSe:]UDSParams<Pt>:PARam), the respective
measurement receiver (b-wave) is significant. E.g. if physical port 1 is equipped with a
step attenuator, then an attenuation factor can be applied to the (redefined) port receiv-
ing b1.
The generated wave is attenuated via SOURce:POWer<Port_no>:ATTenuation.
