RIGOL Chapter 5 To Trigger the Oscilloscope

5-2 DS1000Z-E User Guide

Trigger Source

Press MENU  Source in the trigger control area (TRIGGER) on the front panel to

select the desired trigger source. Analog channels CH1 and CH2, EXT (external

trigger), or the AC Line can all be used as trigger source.

Analog channel input:

Signals input from analog channels CH1 and CH2 can all be used as trigger source.

No matter whether the channel selected is enabled, the channel can work normally.

External trigger input:

The trigger signal (e.g. external clock or signal of the circuit under test) input via the

external trigger input terminal [EXT TRIG] connector can be used as the trigger

source. When the trigger source is selected, rotate TRIGGER

LEVEL to set the

trigger level within the range from -4 V to 4 V.

When the two analog channels are used to acquire data, you can connect the trigger

signal via the [EXT TRIG] connector and use the signal as the external trigger

source.

AC line:

The trigger signal is obtained from the AC power input of the oscilloscope. AC trigger

is usually used to measure signals relevant to the AC power frequency. For example,

stably trigger the waveform output from the transformer of a transformer substation;

it is mainly used in related measurements of the power industry.
