Measure:rjdj:method - Agilent Technologies Infiniium 90000 Series Programmer's Manual

:MEASure:RJDJ:METHod

Command
This command is only available when the EZJIT+ jitter analysis application is licensed.
N O T E
:MEASure:RJDJ:METHod {SPECtral | BOTH}
The :MEASure:RJDJ:METHod command lets you select the method for
random jitter (RJ) analysis, either the SPECtral method or BOTH the
spectral and tail fit methods.
When analyzing jitter with crosstalk or ground bounce effects present in
your signal, select BOTH. When this option is selected, the deterministic
jitter (DJ) that is uncorrelated to the data pattern, also known as bounded
uncorrelated jitter (BUJ), is separated into periodic jitter (PJ) and
aperiodic bounded uncorrelated jitter (ABUJ). ABUJ is caused by crosstalk
and ground bounce effects.
When there are no crosstalk or ground bounce effects present in your
signal, you can select the SPECtral method in order to run faster. When
this option is selected, the deterministic jitter (DJ) that is uncorrelated to
the data pattern is all reported as periodic jitter (PJ).
Example
This example sets the RJDJ method to BOTH the spectral and tail fit
analysis.
myScope.WriteString ":MEASURE:RJDJ:METHod BOTH"
Query

:MEASure:RJDJ:METHod?

The :MEASure:RJDJ:METHod? query returns the selected RJDJ method.
Returned Format
[:MEASure:RJDJ:METHod] {SPEC | BOTH}<NL>
Example This example places the RJDJ method setting the strJitterMethod variable
and displays it on the computer's screen.
myScope.WriteString ":SYSTem:HEADer OFF"
myScope.WriteString ":MEASure:RJDJ:METHod?"
strJitterMethod = myScope.ReadString
Debug.Print strJitterMethod
