State (LF frequency sweep) ← LF Generator
Activates the generation of an LF frequency sweep signal in the "LF Frequency" dialog.
In the "Sources" tab of the analog modulations, the instrument shows the current state
of the LF frequency sweep.
Note: Active sweep mode deactivates other sweeps or lists and vice versa.
Remote command:
[:SOURce<hw>]:LFOutput:FREQuency:MODE on page 1065
Shape ← LF Generator
Selects the waveform shape of the LF signal.
The "Triangle" and "Trapezoid" waveforms require option R&S SMW-K24.
Remote command:
[:SOURce<hw>]:LFOutput<ch>:SHAPe on page 1067
Frequency ← LF Generator
Sets the frequency of the LF generator for sine signals.
Set the signal shape with the parameter Shape.
Remote command:
[:SOURce<hw>]:LFOutput<ch>:FREQuency on page 1063
Period ← LF Generator
Sets the repetition rate of the generated LF signal for triangle, trapezoid or pulse
shapes, see Shape.
The period of sine signals is calculated from the selected Frequency

[:SOURce<hw>]:LFOutput<ch>:SHAPe:PULSe:PERiod on page 1068
Pulse Width ← LF Generator
Sets the pulse duration of the generated pulse signal.
Remote command:
[:SOURce<hw>]:LFOutput<ch>:SHAPe:PULSe:WIDTh on page 1068
Pulse Duty Cycle ← LF Generator
Sets the ratio between the pulse duration and the pulse period in percent.
Remote command:
[:SOURce<hw>]:LFOutput<ch>:SHAPe:PULSe:DCYCle on page 1068
Triangle Rise ← LF Generator
Sets the time required for the triangle signal to change from low level to high level.
