The internal LF signal can the modulation signal source for any of the analog mod-
ulations. The LF signal applies to all modulations which use the internal modulation
signal. Therefore, any modification of the LF signal immediately affects all currently
active modulations.

State (LF frequency sweep)
Status of the LF frequency sweep signal.
You find this parameter in two dialogs:
●
"LF Frequency Sweep" turns on/off the signal generation.
See Sweep mode settings for access.
●
"Analog Modulation Sources" displays the current state (read-only). If it is turned
on, this dialog provides the varying sweep frequency, see Current Frequency.
Note: Active RF frequency, RF level or RF combined sweep modes deactivate the LF
sweep or List mode and vice versa.
Remote command:
[:SOURce<hw>]:LFOutput:FREQuency:MODE on page 656
Shape
Selects the waveform shape of the LF generator signal.
The "Triangle" and "Trapezoid" waveforms require option R&S SMAB-K24.
"Sine"
1 = Period
