trigger source. The output pulse string frequency controlled by pulse string period. The
waveform can output the pulse string of N cycle and infinite type.
2) The waveform generator will trigger by the external digital modulation terminal (FSK Trig
connector) on the back panel when in external source. The waveform generator output pulse
string upon receiving a TTL pulse with designated polarity.
Note: In external triggrt source, trigger output will be hidden in parameter list. Because the
trigger output is also output by the external digital modulation terminal (FSK Trig connector).
This terminal can not be the external trigger input and internal trigger output at the same time.
3) Manual tigger source present in the current channel setting interface on the right side of the
screen. Tap Manual to output a pulse string of N cycle or Inifinite mode.
3.3.7 Trigger Output
When trigger source is internal or manual, the trigger signal (square wave) can be output through
external digital modulation terminal(FSK Trig connector), compatible with TTL level. The default
trigger output is OFF. Rotate multifunction knob or tap TrigOut to step through Close, REdge and
DEdge.
Internal trigger source, the waveform generator outputs a square wave with duty ratio of
50% from external digital modulation terminal (FSK Trig connector) when burst mode starts. The
waveform frequency is equal to pulse string period.
Manual trigger source, the waveform generator outputs a pulse wide than 1μs from
external digital modulation terminal (FSK Trig connector) when burst mode starts.
External trigger source, trigger output will be hidden in parameter list. Because the
trigger output is also output by the external digital modulation terminal (FSK Trig connector). This
terminal can not be the external trigger input and internal trigger output at the same time.
3.3.8 Trigger Edge
The external digital modulation terminal (FSK Trig connector) can be designated edge as input or
output. When the terminal used as input (ExtREdge/ ExtFEdge external trigger source),
ExtREdge means that rising edge of external signal triggers output a pulse string; ExtFEdge
means that falling edge of external signal triggers output a pulse string. In gating mode, when
polarity is positive, the external signal with high level, it will output a pulse string; when polarity is
negative, the external signal with low level, it will output a pulse string. When the terminal used as
