Note:
●
Without the
option only the gain of the measurement receiv-
ers (the b waves) can be statically set (to LNOise or LDIStortion); the reference
receiver always uses automatic gain control (AUTO). With the option available,
also the gain of the reference receivers (the a waves) can be set statically.
●
If you also want to distinguish between different sweep segments, use
[SENSe<Ch>:]SEGMent<Seg>:POWer:GAINcontrol:ALL
Suffix:
<Ch>
.
Channel number
Setting parameters:
<Mode>
AUTO | LDIStortion | LNOise
AUTO
automatic/adaptive gain control (AGC) according to the RF input
level
LDIStortion
fixed, small IF gain, for high input levels
LNOise
fixed, large IF gain, for low input levels
*RST:
LDIStortion
Example:
*RST; :SENSe:POWer:GAINcontrol:GLOBal MANual
