Note:
●
Without the Extended Power Range 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 GC and use [SENSe<Ch>:]POWer:GAINcontrol or
[SENSe<Ch>:]POWer:GAINcontrol:ALL instead, if no distinction between dif-
ferent sweep segments shall be made.
