7-Advanced Function of Oscilloscope

The

Edge triggering

menu is described in the following table.

Function
menu

Settings Description

Slope Rising

Falling

Triggering on the rise edge of the signal.
Triggering on the fall edge of the signal.

Source CH1

CH2

CH1 is used as the trigger source.
CH2 is used as the trigger source.

Trig mode

Auto

Normal

Single

Acquisition of waveforms is possible even if there is no
triggering condition detected.
Acquisition of waveforms can only be done when the
triggering condition is satisfied.
The sampling is performed on a waveform when one
trigger is detected, then stop sampling.

Coupling AC

DC
HF Rjc

LF Rjc

With this mode selected, the DC component is
prevented from passing-though.
All components are allowed.
The HF part of the signal is prohibited and only the LF
component is allowed.
The LF part of the signal is prohibited and only the HF
component is allowed.

SENS

Set trigger sensitivity

Term interpretation

Sensitivity

: Trigger circuit including sluggish in order to exclude the influences from signal

noise and get the stable trigger. The sluggish is adjustable among 0.2div~1.0div. It means when

set on 1.0 div trigger circuit don’t have any response to any signal of PK-PK range

≤

1.0div

which to exclude the influences from signal noise.

7.5.2 Video Triggering

The video trigger type is designed to capture the video signal format,

NTSC, PAL

or

SECAM

.

For any other signal type, use the edge trigger.

Now, you can see a screen that looks like the following figure 38, figure 39 and figure 40.
