## Command Syntax

    :MEASure:EYE:PAM:ELEVel

## Query Syntax

    :MEASure:EYE:PAM:ELEVel?

## Description

Starts the Eye PAM Level measurement where the center amplitude of the selected eye (vertical center) of a PAM signal is measured. Select the eye to be measured using the `:MEASure:EYE:PAM:ELEVel:EYE` child command. To measure the eye levels for all of the eyes on a PAM signal, you must send this command once for each eye as there is no command for simultaneously measuring all eye levels. The query form of the command returns the measured value.

Use the `:MEASure:EYE:PAM:ELEVel:SOURce` command to specify the real-time eye diagram on which to make the measurement.

Command | Equivalent Setting in PAM-N Analysis Setup Dialog Box | Description
--- | --- | ---
`:MEASure:PAM:EYE:ESTiming` | Receiver Sample Timing | Configures the timing for sampling the signal data for all PAM measurements.
`:MEASure:PAM:EYE:ELMethod` | Eye Center Location | Selects the basis for determining the location of an eye's center on the waveform: at maximum eye width or maximum eye height.
`:MEASure:PAM:EYE:PPERcent` | Eye Level Width | Defines the timespan (in percentage of symbol width) over which an eye's amplitude level is measured.
`:MEASure:PAM:AMPLitude:UNITs` | Amplitude Units | Sets the amplitude units for measurement: volts, Watts, or percent.

This measurement can be applied to both NRZ eye and PAM eye diagrams.
