24 Measure Commands
:MEASure:NCJitter
Command
:MEASure:NCJitter <source>,<direction>,<n>,<start>
The :MEASure:NCJitter command measures the N cycle jitter of the
waveform.
<source> {CHANnel<N> | FUNCtion<N> | 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.
FUNCtion<N> and WMEMory<N> are:
An integer, 1 - 4, representing the selected function or waveform memory.
<direction> {RISing | FALLing}, specifies direction of waveform edge to make
measurement.
<n> An integer, 1 to 99, the number of cycles in a group.
<start> An integer, 1 to <n> - 1, typically 1, the cycle to start measuring.
Example This example measures the N cycle jitter on channel 1, rising edge, 5
cycles in a group, starting on the first cycle of the waveform.
myScope.WriteString ":MEASURE:NCJITTER CHANNEL1,RISING,5,1"
Query :MEASure:NCJitter? <source>,<direction>,<n>,<start>
The :MEASure:NCJitter? query returns the measured N cycle jitter time of
the waveform.
Returned Format
[:MEASure:NCJitter] <value>[,<result_state>]<NL>
<value> The N cycle jitter time of the waveform.
NOTE
This command is only available when the E2681A Jitter Analysis Software or the
N5400A/N5401A Software is installed.
