Measure Commands

:MEASure:UNITinterval

Command
This command is only available when the E2681A Jitter Analysis Software or the
N O T E
N5400A/5401A Software is installed.
:MEASure:UNITinterval <source>[,{AUTO | (SEMI,<data_rate>)}]
The :MEASure:UNITinterval command measures the unit interval value of
the selected source. Use the :MEASure:DATarate command/query to
measure the data rate of the source
<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.
<data_rate>
A real number representing the data rate.
Example
This example measures the unit interval of channel 1.
myScope.WriteString ":MEASURE:UNITINTERVAL CHANNEL1"
Query
:MEASure:UNITinterval? <source>[,{AUTO | (SEMI,<data_rate>)}]
The :MEASure:UNITinterval? query returns the measured unit interval.
Returned Format
[:MEASure:UNITinterval] <value>[,<result_state>]<NL>
<value> Unit interval of the source.
<result_state>
If SENDvalid is ON, the result state is returned with the measurement
result. See the :MEASure:RESults table in this chapter for a list of the
result states.
