Measure Commands
:MEASure:DATarate
Command
:MEASure:DATarate <source>[,{AUTO | (SEMI,<data_rate>)}]
The :MEASure:DATarate command measures the data rate in bits per
second for the selected source. Use the :MEASure:UNITinterval
command/query to measure the unit interval 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 specifying the data rate.
Example This example measures the data rate of channel 1.
myScope.WriteString ":MEASURE:DATARATE CHANNEL1"
Query
:MEASure:DATarate? <source>[,{Auto | (SEMI,<data_rate>)}]
The :MEASure:DATarate? query returns the measured data rate.
Returned Format
[:MEASure:DATarate] <value>[,<result_state>]<NL>
<value>
Data rate frequency in bits per second for the selected 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.
N O T E
This command is only available when the E2681A Jitter Analysis Software or the
N5400A/N5401A Software is installed.
