Hardkey and Softkey Reference
LF Out
LF Out Source
Pressing this softkey reveals a menu of choices for LF output sources. You can
choose to output the signal from the internal source 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 the 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. When you use the internal source in this capacity, any modulation with the
internal source selected is turned off.
