27 :TRIGger Commands
:TRIGger[:EDGE]:REJect
(see page 798)
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><NL>
<reject> ::= {OFF | LFR | HFR}
