RF Signal Modes and Characteristics
The CW and Sweep 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.
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 SMC 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 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).
