Manual operation:
See
[SENSe<Ch>:]SEGMent<Seg>:POWer:GAINcontrol:ALL
<Mode>
For the selected segment, this command applies the same manual AGC <Mode> to all
a and b wave receivers.
These settings apply if and only if "Segmented AGC" is enabled (see
]SEGMent<Seg>:POWer:GAINcontrol:CONTrol
).
Note:
●
Without the
option only the gain of the measurement
receivers (the b waves) can be statically set (to LNOise or LDIStortion); the refer-
ence receiver always uses automatic gain control (AUTO). With the option availa-
ble, also the gain of the reference receivers (the a waves) can be set statically.
●
Disable "Segmented AGC" and use
[SENSe<Ch>:]POWer:GAINcontrol:ALL
instead, if no distinction between dif-
ferent sweep segments shall be made.
Suffix:

Sweep segment number
Setting parameters:
<Mode>
LNOise | LDIStortion | AUTO
AUTO – automatic/adaptive gain control (AGC) according to the
RF input level
LNOise – static, large IF gain, for low input levels
LDIStortion – static, small IF gain, for high input levels
Example:
*RST; :SENSe:POWer:GAINcontrol:GLOBal MANual
Enable the manual configuration of independent AGC 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 AGC.
SENSe:SEGMent1:POWer:GAINcontrol:ALL LNO
For sweep segment no. 1, set the AGC mode of all a and b
wave receivers to "Low Noise". Segmented AGC is enabled
automatically.
