4. Modulated Waveform (the sync delay is invalid)
1) When internal modulation source is selected:
the sync signal is a square with 50% duty cycle.
 For AM, FM, PM and PWM, the frequency of the sync signal is the
modulating frequency.
 For ASK, FSK and PSK, the frequency of the sync signal is the
modulating rate.
2) When external modulation source is selected:
The terminal is used to accept the external modulation signal and there is
no sync signal output.
5. Sweep Waveform (the sync delay is invalid)
1) When internal or munual trigger source is selected:
 If “Mark” is disabled:
The sync signal is a square with 50% duty cycle. The sync signal is
TTL high level at the start of the sweep and changes to low level at
the mid-point of the sweep. The frequency of the sync signal is the
reciprocal of the sum of the specified sweep time, return time, start
hold and end hold times.
 If “Mark” is enabled:
For linear and log sweep, the sync signal is TTL high level at the start
of the sweep and changes to low level at the mark frequency.
For step sweep (the sweep points determined by the start frequency,
stop frequency and step number respectively are f
1
, f
2
, ……, f
n
,
f
n+1
…… ), if the mark frequency setting is one of the sweep points
values, the sync signal is TTL high level at the start of the sweep and
will change to low level at the mark frequency point. If the mark
frequency setting is not any one of the sweep points values, the sync
signal will change to low level at the sweep point which is closest to
the mark frequency.
2) When external trigger source is selected:
The terminal is used to accept the external trigger signal and there is no
sync signal output.
