To query the impedance of the RF outputs, use the command :OUTPut<hw>:
IMPedance? on page 277.
State RF
Activated/deactivates the RF output by changing the state of the "RF" functional block.
Alternatively, the RF ON/OFF key can be used.
Remote command:
:OUTPut<hw>[:STATe] on page 278
RF Output State
Activated/deactivates the RF output by enabling/disabling the RF in the "Configure" dia-
log of the "RF" block.
Remote command:
:OUTPut<hw>[:STATe] on page 278
5.3.1.2 RF Signal Modes and Characteristics
●
CW
The RF signal is generated with the set frequency and level. This is the default mode.
●
Sweep
The RF signal is generated as a sweep with the set parameters.
It is not possible to activate frequency, level and LF sweep simultaneously.
●
List Mode
The RF signal is generated on the basis of a list of predefined frequency and level
values. The duration of the individual steps can be predefined.
Instruments connected downstream can be taken into consideration when setting the
frequency and level by entering a frequency and/or level offset.
Automatic level control ("ALC") ensures maximum level accuracy.
User-specific lists which contain level correction values for any frequency range ("User
Correction") can be created to, for example, compensate the cable attenuation in a test
assembly setup.
The R&S Signal Generator generates the RF signal in unmodulated or analog form. The
signal generator is equipped therefore with the following sources for analog modulations:

an internal LF generator
