Command Reference 8-71
:MEASure :PWIDth?
[8 [<threshold>] [,<(@«1|2»)>]]
Positive Pulse Width
A positive pulse width measurement is performed.
This is always a single measurement. If you need an average pulse width mea
-
surement, use the :SENSe subsystem instead.
Parameters
<threshold> parameter sets the trigger levels in volts. If omitted, the auto trigger level is set to
50 percent of the signal.
<(@«1|2»)> is the measurement channel:
(@1) means input A
(@2) means input B
If you omit the channel, the instrument measures on input A.
Complies with standards: SCPI 1991.0, confirmed.
:MEASure :NWIDth?
[8 [<threshold>] [,<(@«1|2»)>]]
Negative Pulse Width
A negative pulse width measurement is performed.
This is always a single measurement. If you need an average pulse width mea

surement, use the :SENSe subsystem instead.
Parameters
<threshold> parameter sets the trigger levels in volts. If omitted, the auto trigger level is set to
50 percent of the signal.
<(@«1|2»)> is the measurement channel:
(@1) means input A
(@2) means input B
If you omit the channel, the instrument measures on input A.
