Subsystem RFGenerator:PULSe (Ramping)
The subsystem RFGenerator:PULSe determines the ramping mode of the internal RF generator. It
corresponds to the Ramping setting in the Generator tab of the Connection Control menu.

Command description
This command determines whether the RF generator generates a CW signal or a GSM-like burst signal.
Subsystem RFGenerator:BANDwidth (Bandwidth)
The subsystem RFGenerator:BANDwidth sets the bandwidth of the modulation filter. It corresponds to
the Modulation Filter setting in the Generator tab of the Connection Control menu.

Command description
This command defines the bandwidth of the modulation filter.
Subsystem RFGenerator:AUXTx... (Aux TX Signal)
The subsystem RFGenerator:AUXTx configures the auxiliary generator signal Aux Tx (only with option
CMU-B95, Additional RF Generator). It corresponds to the Generator Aux Tx section in the Generator
tab of the Connection Control menu.
Aux Tx is an additional TX signal generated by the CMU that can be applied to the one of the RF con-
nectors RF1 or RF2. It is possible to superimpose both RF signals at the same output connector or use
different connectors (commands OUTPut[:TX][:STATe] and OUTPut:AUXTx[:STATe]). Moreover,
it is possible to assign independent external attenuation factors to both signals ([SENSe:] CORRec-
tion:LOSS:OUTPut<nr>[:TX][:MAGNitude], SOURce:CORRection:LOSS:OUTPut
<nr>[:TX][:MAGNitude], [SENSe:]CORRection:LOSS:OUTPut<nr>[:TX][:MAGNitude],
SOURce:CORRection:LOSS:OUTPut<nr>[:TX][:MAGNitude]).
Aux Tx is generated with the modulation settings of the primary TX signal
(...RFGenerator:MODulation...) but with no frequency hopping or ramping.
