3. horizontal displacement of waveform and review
more pre-trigger details. You can observe waveform
in ahead of trigger by observing pre-trigger data. For
instance, burring reason can be shown by
observation and analysis on pre-trigger data after
capturing burring during circuit startup.
4. Pre-trigger/delay trigger: To trigger data acquired
in ahead/after event. Trigger position is often set in
the horizontal center on the screen. You can observe
pre-trigger and delay information of 5div (or 6div).
You can also rotate horizontal position to regulate
Trigger coupling: Trigger coupling can determine
category of signal component conveyed to trigger
circuit. Coupling types include DC, AC, low-
frequency inhibition and high-frequency inhibition.
■ Pass through all components of signals under DC
mode.

Obstruct DC components with signal attenuation
to be less than 400Hz under AC mode.
Obstruct DC components with attenuation of low-
frequency component of less than 80kHz under “low-
frequency inhibition” mode.
Attenuate high-frequency components of more than
80kHz under “high-frequency inhibition” mode.
