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

:MEASure:NOISe:METHod

Command
This command is only available when the EZJIT Complete jitter analysis application is
N O T E
licensed.
:MEASure:NOISe:METHod {SPECtral | BOTH}
The :MEASure:NOISe:METHod command lets you select the method for
random noise (RN) analysis, either the SPECtral method or BOTH the
spectral and tail fit methods.
When analyzing noise with crosstalk or ground bounce effects present in
your signal, select BOTH. When this option is selected, the deterministic
interference (DI) that is uncorrelated to the data pattern, also known as
bounded uncorrelated interference (BUI), is separated into periodic
interference (PI) and aperiodic bounded uncorrelated interference (ABUi).
ABUi 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 interference (DI) that is
uncorrelated to the data pattern is all reported as periodic interference
(PI).
Example
This example sets NOISe method to BOTH the spectral and tail fit
analysis.
myScope.WriteString ":MEASURE:NOISe:METHod BOTH"
Query

:MEASure:NOISe:METHod?

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