## Command Syntax

    :MEASure:EYE:PAM:PP

## Query Syntax

    :MEASure:EYE:PAM:PP?

## Description

Starts the PAM Levels Peak-Peak measurement, which measures the "thickness" of a selected level of a PAM eye diagram. On NRZ signals, the thickness of both level zero and one are measured. Select the actual level to be measured using the `:MEASure:EYE:PAM:PP:LEVel` child command. To measure all the levels on a signal, you must send this command once for each level as there is no command for simultaneously measuring all levels. The query form of the command returns the measured value.

Use the `:MEASure:EYE:PAM:PP: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. Depending on measurement conditions, this command may not affect the measurement.
`: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. Depending on measurement conditions, this command may not affect the measurement.
`: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:EYE:TIME:LTDefinition` | Time of Level | Specifies the method used to locate the time at which to measure an eye's level.
`: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.
