RF Output State
Activated/deactivates the RF output by enabling/disabling the RF in the "Configure" dia-
log of the "RF" block.

5.4.1.2 RF Signal Modes and Characteristics
The CW, Sweep and List modes are available for generating the RF signal.
●
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, even with I/Q modu-
lation.
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
●
an internal pulse generator
●
the external modulation inputs MOD EXT and PULSE EXT.
An external trigger signal for the analog modulations, the sweeps and the LIST mode can
be provided at the INST TRIG input.
The input REF IN is used to input an external instrument reference, and the output REF
OUT serves as the output of the reference frequency (internal or external).
