Description of parameters Def. value Def. unit FW vers.
ON |
OFF
The parameters are set to default values
Some or all parameters differ from the default values
ON
– V3.40
Description of command
If used as a setting command with the parameter ON this command sets all parameters of the RFGenera-
tor:AUXTx subsystem to default values. The setting OFF results in an error message.
If used as a query the command returns whether all parameters are set to default values (ON) or not (OFF).

V3.40
Command description
This command defines the Aux Tx signal level. The resolution is 1 dBm; all values entered are rounded to integer
dBm steps. The 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. The level ranges are also modified if the Tx and Aux Tx signals are both active
and superimposed at the same connector.

Aux Tx frequency 350 MHz Hz V3.40
Command description
This command defines the frequency of the generated Aux Tx signal. The resolution is 200 kHz; all values en-
tered are rounded to 100 kHz steps. If a value between the three distinct frequency bands is entered, the in-
strument generates an error message.
