4-6-2. Trigger Parameter Overview
All the following parameters are common for all the
trigger types unless stated otherwise.
Trigger Source
CH1 ~ 4
Channel 1 ~ 4 input signals
EXT
External trigger input
signal
EXT TRIG
AC Line
AC mains signal
Alternate
Alternate between channel sources for
the trigger source.
EXT Probe Probe trigger source. Set the probe as
either current or voltage.
Trigger Mode
Auto (un-
triggered
roll)
The DCS-9700 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
The DCS-9700 acquires a waveform
only when a trigger event occurs.
