8.1.3 Set trigger source
IT7900 series has four trigger source to choose: trigger by keys (Manual),
Bus trigger (Bus) and External signal trigger (TRIG1/TRIG2). You can select
trigger source according to various test requirements.
8.2 Setting of Surge/Sag Configuration
IT7900 provides surge/sag simulation. The user can add surge/sag to simulate
abnormal voltage fluctuation on the basis of outputting wave, and test usage of
the DUT under this circumstance.
Surge/sag can be added to any waveform, the basic waveform is selected from
the Config menu.
