The modulation signal is output at the LF OUTPUT connector at the rear of the instru-
ments.
SCPI command:
[:SOURce]:LFOutput[:STATe] on page 742
Output Voltage - LF Output
Sets the output voltage of the LF output. The entered value determines the peak voltage.
SCPI command:
[:SOURce]:LFOutput:VOLTage on page 746
LF Gen Frequency
Sets the frequency of the LF generator. This setting affects all analog modulations which
use the LF generator as the internal modulation source.
SCPI command:
[:SOURce]:LFOutput:FREQuency on page 740
5.5.13 Sweep Mode
5.5.13.1 Overview
The R&S Signal Generator offers three different sweep types (frequency sweep, level
sweep and LF 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 trig-
gering mode (automatic, internal and external).
Sweeps and List mode can not be activated simultaneously, they deactivate each other.
A phase continuous frequency sweep can be generated after activating the phase con-
tinuous mode, see "Setting a Phase Continuous Frequency Sweep" on page 201.
Setting a sweep
A sweep is set in five basic steps which are shown below taking a frequency sweep as
an example.
1. Set the sweep range ("Start Freq" and "Stop Freq" or "Center Freq" and "Span").
2. Select linear or logarithmic sweep spacing ("Spacing").
3. Set the step width ("Step Lin/Log") and dwell time ("Dwell Time").
4. Activate the sweep ("Mode" to Auto, Single, Step or Extern Single, Extern Step).
5. Trigger the sweep, except for Auto mode ("Execute Single Sweep", Current Fre-
quency or External Trigger Signal).
