Measure Commands
:MEASure:CTCDutycycle
Command
:MEASure:CTCDutycycle <source>,<direction>
The :MEASure:CYCDutycycle command measures the cycle- to- cycle duty
cycle jitter (%) of the waveform.
<source>
{CHANnel<N> | FUNCtion<F> | WMEMory<N> | CLOCk | MTRend |
MSPectrum | EQUalized}
MTRend and MSPectrum sources are only available if the oscilloscope has
the EZJIT option installed and the feature is enabled.
The CLOCk source is only available if the oscilloscope has the High Speed
Serial option installed and the feature is enabled.
The EQUalized source is only available if the oscilloscope has the High
Speed Serial option and the Serial Data Equalization option installed and
the features are enabled. This command uses the Feed- Forward Equalized
(FFE) signal as the source.
<N>
CHANnel<N> is an integer, 1- 4.
WMEMory<N> is an integer, 1- 4.
<F>
FUNCtion<F> is an integer, 1- 16.
<direction> {RISing | FALLing}
Specifies direction of waveform edge to make measurement.
Example This example measures the cycle- to- cycle duty cycle on the rising edge of
channel 1.
myScope.WriteString ":MEASURE:CTCDUTYCYCLE CHANNEL1,RISING"
Query
:MEASure:CTCDutycycle? <source>,<direction>
The :MEASure:CTCDutycycle? query returns the cycle- to- cycle duty cycle
jitter (%) measurement.
Returned Format
[:MEASure:CTCDutycycle <value>[,<result_state>]<NL>
<value>
The cycle- to- cycle duty cycle jitter (%) of the waveform.
<result_state> If SENDVALID is ON, the result state is returned with the measurement
result. Refer to the MEASure:RESults command, for a list of the result
states.
N O T E
This command is only available when the E2681A Jitter Analysis Software or the
N5400A/N5401A Software is installed.
