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.
