value). When the waveform output is negative, the sync signal is TTL
low relative to the 0V voltage (or DC offset value).
For arbitrary waveform, the sync signal is a square wave with a
variable duty cycle. When the output waveform amplitude reaches a
certain value, the sync signal is TTL high.
For AM, FM, PM, and PWM, for internal modulation, the sync signal is
referenced to the modulation frequency, and the sync signal is a
square wave with a 50% duty cycle. In the first half of the modulation
waveform, the sync signal is TTL high. When external modulation is
performed, there is no sync signal output.
For ASK, FSK, PSK, BPSK, QPSK, 3FSK, 4FSK, the synchronization
signal is referenced to the keying frequency, and the synchronization
signal is a square wave with a duty cycle of 50%. There is no sync
signal output during external modulation.
For OSK, the sync signal is referenced to the keyed frequency and the
sync signal is a square wave with a 50% duty cycle. When the internal
crystal oscillator starts, the sync signal is TTL high.
For N-cycle bursts, the sync signal is TTL high at the beginning of the
burst. At the end of the specified number of cycles, the sync signal is
TTL low (if the waveform has an associated Phase, it may not be a
zero crossing). For an infinite count pulse train, the sync signal is the
same as the sync signal of the continuous waveform.
For external gated bursts, the sync signal follows its gate signal. Note:
This signal does not become TTL low until the end of the last cycle (if
the waveform has an associated starting phase, it may not be a zero
crossing).
Align Phase : Select Align Phase in the bottom menu to align the initial phase
of two channel signals.
