Measure Commands

:MEASure:TIEData

Command
This command is only available when the E2681A Jitter Analysis Software, Serial Data
N O T E
Analysis, or the N5400A/5401A Software is installed.
:MEASure:TIEData <source>,{SECond | UNITinterval}, {AUTO | CUSTOM,<data_
rate> | VARiable,<data_rate>,<bandwidth> | CLOCk}
The :MEASure:TIEData command measures data time interval error. You
can set the units of the measurement by selecting SECond (seconds) or
UNITinterval. If AUTO is selected, the oscilloscope selects the ideal data
rate. If CUSTom is selected, you can enter your own ideal constant data
rate. If VARiable is selected, a first order PLL clock recovery is used at a
given data rate and loop bandwidth. If CLOCk is given, clock recovery as
specified with the :MEASure:CLOCk:METHod is used.
<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- 2, for two channel Infiniium Oscilloscope. An integer, 1- 4, for
all other Infiniium Oscilloscope models.
WMEMory<N> is an integer, 1- 4.
<F>
FUNCtion<F> is an integer, 1- 16.
<data_rate> A real number for the ideal data rate for clock recovery.
<bandwidth> A real number for the loop bandwidth of the PLL clock recovery method.
Example
This example measures the data time interval error on channel 1, ideal
data rate set to automatic, units set to seconds.
