Return : The query returns POSItive，NEGAtive
Example :TRIGger:PULSe:POLarity POSItive /* Set positive pulse
trigger */
:TRIGger:PULSe:POLarity? /* The query returns POSItive*/
TRIGger:PULSe:WHEN
Syntax :TRIGger:PULSe:WHEN <when>
:TRIGger:PULSe:WHEN?
Description : Set or query the trigger condition in pulse width trigger
Parameter :<when> ::= < EQUAl| NEQUal| GREAt| LESS>
Explanation :EQUAl: you need to specify a pulse width(refer to
TRIGger:PULSe:WIDth), The oscilloscope triggers when the
positive pulse width of the input signal is equal than the
specified Pulse Width.
:NEQUal: you need to specify a pulse width(refer to
TRIGger:PULSe:WIDth), The oscilloscope triggers when the
positive pulse width of the input signal is not equal to
the specified Pulse Width.
:GREAt: you need to specify a pulse width(refer to
TRIGger:PULSe:WIDth), The oscilloscope triggers when the
positive pulse width of the input signal is greater than
the specified Pulse Width.
:LESS: you need to specify a pulse width(refer to
TRIGger:PULSe:WIDth), The oscilloscope triggers when the
positive pulse width of the input signal is lesser than the
specified Pulse Width.
Return : The query returns EQUAl，NEQUal，GREAt，LESS
Example :TRIGger:PULSe:WHEN NEQUal /*Set the trigger condition
to NEQUal*/
:TRIGger:PULSe:WHEN? /* The query returns NEQUal*/
TRIGger:PULSe:WIDth
Syntax :TRIGger:PULSe:WIDth <value>
:TRIGger:PULSe:WIDth?
Description : Set or query the pulse width in pulse width trigger
