port.
3.11.9 Trigger edge:
Press
〖
Trigger Edge
〗
to choose trigger signal’s effective edge. Trigger edge’s
setting is only available for external trigger.
When trigger edge is rising edge, burst signal will output setting cycle numbers from the start
phase. Rising edge means trigger signal changes from 0 to 1.
When trigger edge is falling edge, burst signal will output setting cycle numbers from the start
phase. Falling edge means trigger signal changes from 1 to 0.
3.11.10 Trigger polarity
: Press
〖
Polarity
〗
to choose external trigger signal’s polarity. Trigger
polarity is only available for Gate control.
When it is positive:
When Gate control signal is 1, burst signal will output from start phase. When gate control is 0,
burst signal will stop outputting to the level correspondent to start phase after the last cycle
waveform is completed.
When it is negative:
When gate control signal is 0, burst signal will output from start phase. When gate control is 1,
burst signal will stop outputting to the level correspondent to start phase after the last cycle
waveform is completed.
3.11.11 Trigger output
: Press
〖
TrigOut
〗
to choose trigger signal’s output mode. If you choose
‘off’, no trigger signal will be output. If you choose ‘Rising edge’, when burst signal starts to
output, trigger signal will change from 0 to 1 and remain in 1. When the output is done, it will
change from 1 to 0. If you choose ‘Falling edge’, when burst signal starts to output, trigger signal
will change from 1 to 0 and remain in 0. When the output is done, it will change from 0 to 1.
3.11.12 Sync output
: Sync signal’s period is equal to burst period, sync signal’s rising edge is in
burst signal’s starting point, and sync signal’s falling edge is in burst signal’s ending point. In burst
signal outputting period, sync signal will be high level, while in burst signal stopping period, sync
signal will be low level.
If external trigger or manual trigger is used, sync signal will be decided by external trigger or
manual trigger signal.
