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 SMB 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 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).
