Mod Gen block
The internal modulation sources are configured in this block. The LF frequency sweep can be
activated here and an internal LF generator is available as the internal source for the analog
modulations AM, FM and PHiM. The used modulation shape is a sine wave signal.
The internal modulation generator signal is provided at the LF output on the front of the instrument. The
LF output signal and the modulations sources for the analog modulations AM, FM and PhiM can be
selected independently from each other.
A pulse generator provides single and double pulse modulation with selectable pulse widths and
periods. The internal pulse generator signal is provided at the PULSE VIDEO output connector on the
rear panel of the instrument.
The R&S SMC Signal Generator offers three different sweep types (RF frequency sweep, level sweep
and LF frequency sweep) to be activated alternatively. Each type has 6 modes which differ with respect
to the sweep cycle mode (continuous, individual and step-by-step) and triggering mode (automatic,
internal and external). In the Mod Gen block, the LF sweep is configured. Frequency and level sweep
settings are accessed via the RF block.
The status line in the block displays whether the LF generator, the pulse generator and/or a sweep are
active.
