UTG9000T Series Function Abitrary Waveform Generator

3.3.2 Burst Type
UTG9000T can output three types of pulse train, N cycle, gating and infinite. The default type is N
cycle.
1) N cycle mode
Tap NCycle to turn on N cycle mode, the waveform generator will output a waveform with
designated cycle number (pulse string). After output a designated number cycle number, the
waveform generator will stop and wait for the next trigger. The trigger source of pulse string
can be internal, external or manual in this mode. Rotate multifunction knob or tap TrigSrc tab
to step through Internal, ExtREdge, ExtFEdge and Manul.
Note: When trigger source is ExtREdge, ExtFEdge, trigger out option 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.
2) Gating mode
Tap Gate to turn on gating mode, trigger source, trigger output, trigger period and cycle
number will be hidden in parameter list. It can only use the external trigger source, the
waveform generator trigged by the external digital modulation terminal (FSK Trig connector)
on the back panel. The waveform generator output succession waveform when trigger the
input signal is positive polarity with high level; when trigger the input signal at low level,
complete the current waveform period first, and then stop the output, keep the selected
waveform start phase at the corresponding level. For noise waveform, if the gated signal is
fake, the output will stop immediately. Rotate multifunction, push direction key or tap Polarity
to step through Positive and Negative.
