Measure Commands
:MEASure:TIEClock2
Command
:MEASure:TIEClock2 <source>,{SECond | UNITinterval},
<direction>,{AUTO | CUSTOM,<frequency>} | {VARiable,<frequency>,<bandwid
th>} | CLOCk}
The :MEASure:TIEClock2 command measures time interval error on a
clock. You can set the units of the measurement by selecting SECond
(seconds) or UNITinterval. If AUTO is selected, the oscilloscope selects the
ideal constant clock frequency. If CUSTom is selected, you can enter your
own ideal clock frequency. If VARiable is selected, a first order PLL clock
recovery is used at the give clock frequency and loop bandwidth. If CLOCk
is given, clock recovery is specified with the :MEASure:CLOCk:METHod
command.
<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.
<direction> {RISing | FALLing | BOTH}

Turn Off Headers
When receiving numeric data into numeric variables, turn off the headers. Otherwise, the
headers may cause misinterpretation of returned data.
N O T E
This command is only available when the E2681A Jitter Analysis Software or the
N5400A/5401A Software is installed.
