:TRIGger Commands 28

Agilent InfiniiVision 3000 X-Series Oscilloscopes Programmer's Guide 659

:TRIGger[:EDGE]:REJect

(see page 860)

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

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