Syntax

:TRIGger:SWEep <sweep>

:TRIGger:SWEep?

Description

Set or query the trigger mode.

Parameter

Name Type Range Default

<sweep> Discrete {AUTO|NORMal|SINGle} AUTO

Explanation

 AUTO:

After this mode is selected, the oscilloscope starts searching for trigger signals that meet the

specified condition. If trigger signals that meet the specified condition are found, “T’D” is displayed

at the upper-left corner of the user interface and stable waveform is displayed. Otherwise, “AUTO” is

displayed and unstable waveform is displayed.

 NORMal:

After this mode is selected, the oscilloscope enters the wait-for-trigger state and starts searching for

trigger signals that meet the specified condition. If trigger signals that meet the specified condition

are found, “T’D” is displayed in the running status bar and stable waveform is displayed. Otherwise,

“WAIT” is displayed and the waveform of the last trigger (there is a last trigger) or no waveform

(there is not a last trigger) is displayed.

 SINGle:

When this mode is selected, the backlight of SINGLE turns on. The oscilloscope enters the

wait-for-trigger state and starts searching for trigger signals that meet the specified condition. If

trigger signals that meet the specified condition are found, “T’D” is displayed in the running status

bar and stable waveform is displayed. Then, the oscilloscope stops sweeping, the backlight of

RUN/STOP turns on and “STOP” is displayed in the running status bar. Otherwise, “WAIT” is

displayed in the running status bar and no waveform is displayed.

Return Format

The query returns AUTO, NORM or SING.
