Trigger mode Auto
GDS-2000 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
waveform at slower timebase.
Normal
GDS-2000 acquires waveform only when
a trigger event occurs.
Single
GDS-2000 acquires
waveform once when a
trigger event occurs, then
stop acquiring. Press the
Run/Stop key to acquire
waveform again.
Run/Stop
Auto level
When turning this function ON, GDS-2000
automatically adjusts the trigger level to the center
amplitude of the waveform.
Holdoff
The holdoff function defines the waiting period
before GDS-2000 starts triggering again after a
trigger point. The Holdoff function ensures a
stable display.
