2.5 Sync Output (CH1)
Sync output provides CH1 channel sync output, and all standard functions (except DC and
noise) have a related sync signal.
When sine wave and triangle wave are outputted, the sync signal is square wave with 50% duty
cycle. When waveform output is positive, relative to 0V voltage (or DC offset), and the sync
signal is TTL high-level.
When square wave and pulse wave are outputted, the duty cycle of sync signal is same as that of
the waveform. When waveform output is positive, relative to 0V voltage (or DC offset), and the
sync signal is TTL high-level.
For internal modulated AM, FM and PM, the sync signal takes modulation waves (not carrier)
as references, and the sync signal is square waves of 50% duty cycle. During the first half
modulation waveform period, the sync signal is a TTL High-level.
For external modulated AM, FM and PM, the sync signal takes carriers (not modulation wave)
as references, and the sync signal is square waves of 50% duty cycle.
For ASK
,
the sync signal takes the modulation amplitude as a reference, and the sync signal is
square waves of 50% duty cycle. For the modulation amplitude, at the time of conversion, the
sync signal is a TTL high-level.
For FSK, the sync signal takes the hop frequency as a reference, and the sync signal is square
waves of 50% duty cycle. For the hop frequency, at the time of conversion, the sync signal is a
TTL high-level.
For PSK
,
the sync signal takes the modulation phase as a reference, and the sync signal is square
waves of 50% duty cycle. For the modulation phase, at the time of conversion, the sync signal is
a TTL high-level.
