Traditional positive 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{:PDUTycycle|:DCYCle}?[ [<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:PDUTYCYCLE?
might return
+5.097555E-001

duty cycle is 50.97%
MEASure:PERiod? (Query Only)
A period time measurement is taken on a single period. Measuring time set by the
command does not affect the measurement.
The <expected value> and <resolution> are used to calculate the Measurement
Time (
Group
Measurement
Syntax
MEASure:PERiod?[ [<expected value>
[,<resolution>]][,<(@{1|2|3})>]]
Arguments
<EXPECTED VALUE>
is the expected Period,
<RESOLUTION>
is the required resolution,
<(@{1|2|3})>
is the measurement channel:
(@1)
means input A
(@2)
means input B
(@3)
means input C (RF input option).
