33 :TRIGger Commands

:TRIGger[:EDGE]:REJect

(see page 1276)

Command Syntax

:TRIGger[:EDGE]:REJect <reject>

<reject> ::= {OFF | LFReject | HFReject}

The :TRIGger[:EDGE]:REJect command turns the low-frequency or high-frequency

reject filter on or off. You can turn on one of these filters at a time.

• The high frequency reject filter adds a 50 kHz low-pass filter in the trigger path

to remove high frequency components from the trigger waveform. Use the high

frequency reject filter to remove high-frequency noise, such as AM or FM

broadcast stations, from the trigger path.

• The low frequency reject filter adds a 50 kHz high-pass filter in series with the

trigger waveform to remove any unwanted low frequency components from a

trigger waveform, such as power line frequencies, that can interfere with proper

triggering.

Query Syntax

:TRIGger[:EDGE]:REJect?

The :TRIGger[:EDGE]:REJect? query returns the current status of the reject filter.

Return Format

<reject> ::= {OFF | LFR | HFR}

NOTE

The :TRIGger[:EDGE]:REJect and the :TRIGger[:EDGE]:COUPling selections are coupled.

Changing the setting of the :TRIGger[:EDGE]:COUPling can change the COUPling setting.
