Arbitrary:
it allows to load a Modulating Waveform from file
. By default, the “Arbitrary”

Marker Out behaviour in Modulation Run Mode
If the modulating source is
Internal
, the
Marker Out
generates a square wave synchronous with the
modulating waveform. The leading edge of this pulse is positioned at the beginning of the modulating
waveform.
If the modulating source is
External
, the
Marker Out
is disabled.
