:TRIGger:SWEep
Syntax :TRIGger:SWEep <sweep>
:TRIGger:SWEep?
Description
Sets or queries the trigger mode.
Parameter
Name
Type
Range
Default
<sweep>
Discrete
{AUTO|NORMal|SINGle}
AUTO
Remarks 
AUTO: Auto trigger. The waveforms are displayed no matter whether the trigger
conditions are met.
 NORMal: normal trigger. The waveforms are displayed when trigger conditions
are met. If the trigger conditions are not met, the oscilloscope displays the
original waveforms and waits for another trigger.
 SINGle: single trigger. The oscilloscope waits for a trigger, displays the
waveforms when the trigger conditions are met, and then stops.
Return
Format
The query returns AUTO, NORM, or SING.
Example
:TRIGger:SWEep SINGle /*Selects the single trigger mode.*/
:TRIGger:SWEep? /*The query returns SING.*/
:TRIGger:HOLDoff
Syntax :TRIGger:HOLDoff <value>
:TRIGger:HOLDoff?
Description
Sets or queries the trigger holdoff time. The default unit is s.
Parameter
Name
Type
Range
Default
<value>
Real
16 ns to 10 s
16ns
Remarks  Trigger holdoff can be used to stably trigger complex waveforms (such as pulse
waveform). Holdoff time indicates the time that the oscillscope waits for
re-arming the trigger module. The oscilloscope will not trigger before the holdoff
time expires.
 Holdoff time is no available for Video trigger, Timeout trigger, Setup&Hold
trigger, Nth Edge trigger, RS232 trigger, I2C trigger, SPI trigger, CAN trigger,
FlexRay trigger, LIN trigger, I2S trigger, or 1553B trigger.
Return
Format
The query returns the trigger holdoff time in scientific notation.
Example
:TRIGger:HOLDoff 0.0000002 /*Sets the trigger holdoff time to 200 ns.*/
:TRIGger:HOLDoff? /*The query returns 2.000000E-7.*/
