Trigger Sensitivity 

(Edge Trigger Type)

DC: CH 1 or CH 2 (Typical) 1div from DC to 10 MHz; 1.5 div from 10 MHz to FullEXT(Typical) 200 mV from DC to 40 MHz

EXT/5(Typical) 1 V from DC to 40 MHz

AC: Attenuates signals below 10 Hz

HF Reject: Attenuates signals above 80 kHz

LF Reject: Attenuates signals below 150 kHz

Noise Reject: Reduces trigger sensitivity

Trigger Level Range CH 1, CH 2: ±8 divisions from center of screenEXT: ±1.2 V EXT/5:  ±6 V
Trigger Level Accuracy, 

typical (Accuracy is for signals having rise and fall times ≥20 ns)

CH 1, CH 2: ±(0.3 div × V/div) (within  ±4 divisions from center of screen)EXT: ±(6% of setting +40 mV)
