Trigger system

Trigger sources

Analog channel (1 ~ 4), digital channel (D0 ~ D15), line, external, WaveGen (1, 2, or Mod)

(FM/FSK)

Trigger modes

Normal

Requires trigger event for oscilloscope to trigger

Auto

Triggers automatically in absence of trigger event

Single

Front panel button that triggers only once on a trigger event. Press [Single] button again

for oscilloscope to find another trigger event, or press [Run] front-panel button to trigger

continuously in either auto or normal mode

Force

Front panel button that forces a trigger

Trigger coupling

DC

DC coupled trigger

AC

AC coupled trigger, cutoff frequency: < 10 Hz (internal); < 50 Hz (external)

HF reject

High-frequency reject, cutoff frequency ~ 50 kHz

LF reject

Low-frequency reject, cutoff frequency ~ 50 kHz

Noise reject

Adds hysteresis to the trigger circuitry. Selectable OFF or ON, decreases sensitivity 2x

Trigger holdoff range
