LF Out Source
Supported PSG-A Series
Use this softkey to access a menu of choices that enables you to select an internally
generated source for the low frequency output. You can choose to output the signal from
one of the internal sources as it is being used by a modulation or you can use the internal
source as a function generator and select that signal to output at the LF OUTPUT
connector.
If you choose an internal source, the frequency and shape of the signal at the
LF OUTPUT connector is set by the internal source as it is being used by a modulation.
For example, if the internal source is currently assigned to an AM path configuration
and AM is turned on, the signal output at the LF OUTPUT connector will have the
frequency and shape of the amplitude modulating signal. You can scale the amplitude of
the output signal using the
LF Out Amplitude softkey.
If you choose to set the internal source as a function generator, you can select a
frequency and shape in addition to selecting the amplitude for the LF output signal.

Remarks When you use an internal source as a function generator, any
modulation with the internal source selected is turned off.
