► To open the "LF Generator / Output" dialog, select "Mod Gen > Configure > LF
Generator / Output" or use the MENU key under "Mod Gen".
The dialog provides access to the configuration of the internal modulation genera-
tors, and you can activate the output of the LF signal
Alternatively, you can perform the settings also in the correpsonding dialogs of the
analog modulations, like "Amplitude Modulation". The configured LF signal applies
to all modulations which use the internal modulation sources, and to the LF output.
The remote commands required to define these settings are described in Chap-
ter 7.13.6, "SOURce:LFOutput Subsystem", on page 299.
5.5.2.1 LF Output Dialog
LF Output State
Activates the LF output. This setting has no effect on the modulations.
The modulation signal is output at the LF OUTPUT connector of the instrument.
Remote command:
[:SOURce]:LFOutput[:STATe] on page 302
LF Output Voltage
Sets the voltage (peak) of the LF output signal.
Remote command:
[:SOURce]:LFOutput:VOLTage on page 307
LF Gen Freq
Sets the frequency of the LF generator.
This setting affects all analog modulations which use the LF generator as the internal
modulation source.
Remote command:
[:SOURce]:LFOutput<ch>:FREQuency on page 300
5.5.3 LF Frequency Sweep
The "LF Frequency Sweep" dialog is used to configure and activate an LF frequency
sweep signal.
To open the "LF Frequency Sweep" dialog, select "Mod Gen > Configure > LF Fre-
quency Sweep" or use the MENU key under "Mod Gen".
