Command Descriptions
MEASure:NDUTycycle? (Query Only)
Traditional negative duty cycle measurement is performed. That is, the ratio
between the on time and the off time of the input pulse is measured.
Group
Measurement
Syntax
MEASure:NDUTycycle?[ [<threshold>] [,(@{1|2})]]
Arguments
<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 (@1).
Examples
MEASURE:NDUTYCYCLE?
might 5.097555E-001. In this example, the
duty cycle is 50.97%.
MEASure:NWIDth? (Query Only)
A negative pulse width measurement is performed.
This is always a single measurement. If you need an average pulse width
measurement, use the SENSe subsystem instead.
Group
Measurement
Syntax
MEASure:NWIDth?[ [<threshold>] [,<(@{1|2})>] ]
Arguments
<THRESHOLD>
parameter sets the trigger levels in volts. If omitted, the auto
trigger level is set to 50 percent of the signal.
<(@{1|2})>
