MULTIFUNCTION GENERATOR
i) To output modulation sync signal, modulation waveform signal → Sync output
setting
Perform the sync output setting with [SyncOut] (sync output) on the 2nd page of the setting
screen. The sync output setting can be chosen from the following three.
・Signal synchronized with reference phase of waveform [Sync]
・Signal synchronized with internal modulation waveform [ModSync]
・Internal modulation waveform [ModFctn]
■ When [Sync] is selected
A TTL level signal that rises at the reference phase of the waveform is output from the sync/
sub-output terminal.
■ When [ModSync] is selected
A TTL level signal synchronized with the internal modulation waveform is output from the
sync/sub-output terminal. This is a 50% duty square wave that rises at the zero phase
position of the internal modulation waveform. If the internal modulation waveform is noise,
it is fixed to low level.
When the signal being modulated is observed with an oscilloscope, it can be used as the
trigger signal for the oscilloscope.
■ When [ModFctn] is selected
The internal modulation waveform is output from the sync/sub-output terminal. The signal
level is ±3 V/open.
[ModFctn] cannot be selected when the modulation type is FSK or PSK.
