Trigger
The trigger settings configure the conditions under which the GBS-
1000 can capture the incoming signals.
Trigger type overview
Edge Triggers when the signal crosses an amplitude
threshold in either a positive or negative slope.
Video Extracts a sync pulse from a video format signal,
and triggers on a specific line or field.
Pulse Triggers when the pulse width of the signal is too
narrow or too wide compared to the setting.
Trigger parameter overview
Trigger source CH1 ~ 4 Channel 1 ~ 4 input signals
Line AC mains signal
Trigger mode Auto GBS-1000 generates an internal trigger if
there is no trigger event, to make sure
waveforms are constantly updated
regardless of trigger events. Select this
mode especially when viewing rolling
waveforms at slower timebases.
Normal GBS-1000 acquires a waveform only
when a trigger event occurs.
