:TRIGger:HOLDoff
Syntax :TRIGger:HOLDoff <value>
Set or query the trigger holdoff time. The default unit is s.
Parameter
Explanation Trigger holdoff can be used to stably trigger the complex waveforms (such as pulse
series). Holdoff time is the time that the oscilloscope waits before re-arming the
trigger circuitry. The oscilloscope will not trigger until the holdoff time expires.
When the trigger type is video, RS232, I2C or SPI, this setting will be not available.
Return
The query retuns the trigger holdoff time in scientific notation.
Example
:TRIGger:HOLDoff 0.0000002 /*Set the trigger holdoff time to 200ns*/
:TRIGger:HOLDoff? /*The query returns 2.000000e-07*/
:TRIGger:NREJect
Syntax :TRIGger:NREJect <bool>
:TRIGger:NREJect?
Enable or disable the noise rejection, or query the status of the noise rejection.
Parameter
<bool> Bool {{0|OFF}|{1|ON}} 0|OFF
Noise rejection reduces the possibility of noise trigger.
Return
Format
The query returns 0 or 1.
