:MEASure:AMPLitude:DEFine:LOCation:PERCent:LEVel
Command Syntax
:MEASure:AMPLitude:DEFine:LOCation:PERCent:LEVel{0|1|2|3} <percent>
<percent> is an double.
Query Syntax
:MEASure:AMPLitude:DEFine:LOCation:PERCent:LEVel?
Description
This command specifies the location within the unit interval at which the noise and interference will be measured on NRZ or PAM4 waveforms. The location is specified as a percentage. A 0% entry corresponds to the left crossing point while a 100% entry corresponds to the right crossing point. A 50% entry (the default) corresponds to the center of the eye. The specified location must be within the range of 5.0% and 95.0%.
For NRZ signals, only the :LEVel0
can be defined and used. For PAM4 signals, four levels can be defined: :LEVel0
, :LEVel1
, :LEVel2
, and :LEVel3
.

Amplitude analysis must be turned on before the first interference measurement can be made. Use the :MEASure:AMPLitude:DEFine:ANALysis
command.
Requires FlexDCA revision A.05.60 and above.
This command replaces deprecated command :MEASure:AMPLitude:DEFine:LOCation
.
Common Numerical Child Commands
