Command description 
This command is always a query. It returns the current generator status. 
 
 
 
Subsystem RFGenerator... (Generator Settings) 
The subsystem RFGenerator... determines the level and frequency of the RF generator. It corresponds 
to the input field RF Level and the Frequency softkey in the Generator panel (in Connection Control, 
Generator tab and in the Analyzer/Generator menu).

V1.15 
Command description 
This command defines the RF generator level. The permissible value range depends on the used RF output of 
the CMU and the external attenuation. Moreover, in the SSB mode (see command 
SOURce:RFGenerator:MODulation SSB), the level ranges for all three connectors are shifted by –2 dB, and 
the default value for RF1 OUT is –29.0 dBm. The level ranges are also modified if the Tx and Aux Tx signals are 
both active and superimposed at the same connector.

Command description 
This command defines the output frequency of the RF generator. The usable frequency range exceeds the speci-
fied range, see data sheet.
