Query Syntax

:MEASure:EYE:PAM:RMS:STATus?

Query Response

{CORR | INV | QUES}

CORR

The measurement result is correct.

INV

The measurement result is invalid. A question mark (?) is shown in the displayed results table instead of a measurement result.

QUES

The measurement result is questionable. A question mark (?) is shown in the displayed results table next to the measurement result.

Description

Queries the status of the levels RMS measurement for PAM4 or NRZ signals. Use the :STATus:REASon? child query to determine the reason for an invalid or questionable measurement. Additional information about the failure may be available using the :STATus:DETails? child query.

Measurement Identification

Avoid subtle programming errors! To ensure that the correct measurement is installed or queried, always explicitly identify a measurement when installing a measurement or querying a measured value, status, or detail. To identify a measurement, specify the measurement's source waveform (:SOURce child command). With some measurements, you may also need to specify other identifying values. Generally, when selecting a measurement using FlexDCA's GUI, if a dialog appears prompting you to select values, you should explicitly specify these values when remotely identifying the measurement. More information.

For example, to return the status of the measurement, :MEASure:EYE:PAM:RMS:

flex.write(':MEASure:EYE:PAM:RMS:SOURce CHAN1A')
if flex.query(':MEASure:EYE:PAM:RMS:STATus?') == 'CORR';
    measurement = flex.query(':MEASure:EYE:PAM:RMS?')
else:
	details = flex.query(':MEASure:EYE:PAM:RMS:STATus:DETails?')
	reason = flex.query(':MEASure:EYE:PAM:RMS:STATus:REASon?')
