Setup Of Trigger System - UNI-T UTD2025C Operating Manual

Setup of trigger system

Trigger can determine data acquisition time and
waveform display for digital storage oscillograph. It
can convert instable display to meaningful
waveform once correct setup. Digital storage
oscillograph will collect sufficient data to map
waveform in the left side of trigger point firstly. It
will acquire data continuously and synchronously
when waiting for trigger conditions. It also will
acquire sufficient data continuously to map
waveform in the right side of trigger point. Trigger
control area of operation panel of digital storage
oscillograph includes trigger level adjustment knob
and trigger menu key of [TRIG MENU];
5.7-inch oscillograph will set 50% of trigger level in
vertical middle point of signal (and realize
UTD2000L /2000EX by press [SET TO ZERO] key).
It has to press forced trigger key of [FORCE].
