Query Syntax

:MEASure:JITTer:POJitter:EOJ?

Query Response

Description

Send this command to move the Even-Odd Jitter measurement, EOJ, results to the top of Timing Jitter panel. Send the query form of this command to return the EOJ measurement result. This measurement does not support measurement limit tests.

Before the :MEASure:JITTer:POJitter:EOJ command can be used, you must turn on Even-Odd Jitter measurements by sending the :MEASure:JITTer:POJitter:STATe command.

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:JITTer:POJitter:EOJ

flex.write(':MEASure:JITTer:POJitter:EOJ:SOURce CHAN1A')
if flex.query(':MEASure:JITTer:POJitter:EOJ:STATus?') == 'CORR';
    measurement = flex.query(':MEASure:JITTer:POJitter:EOJ?')
else:
	details = flex.query(':MEASure:JITTer:POJitter:EOJ:STATus:DETails?')
	reason = flex.query(':MEASure:JITTer:POJitter:EOJ:STATus:REASon?')

Measurement Ready?

To confirm that the measurement is ready to read, you can query the measurement's status:

if ('CORR' in Flex.query(':MEASure:JITTer:POJitter:EOJ:STATus?')):
	measurement = Flex.query(':MEASure:JITTer:POJitter:EOJ?')

If averaging is turned on (:ACQuire:AVERaging), you can also confirm if the measurement result is ready by comparing the number of specified averages (:ACQuire:ECOunt?) versus the number of measurement sweeps that have occurred (:MEASure:JITTer:POJitter:EOJ:COUNt?). The technique uses the :COUNt? common measurement query. For example,

if (Flex.query(':MEASure:JITTer:POJitter:EOJ:COUNt?') >= Flex.query(':ACQuire:ECOUNt?')):
	measurement = Flex.query(':MEASure:JITTer:POJitter:EOJ?')

You can also use an acquisition limit lest to test that a number of waveform samples, or pattern acquisitions have completed before returning a measurement. Refer to the :LTESt:ACQuire:CTYPe command.

Common Measurement Child Queries

This command supports the use of the following common measurement queries: :LOCation?, :COUNt?, :MAXimum?, :MINimum?, :MEAN?, and :SDEViation?.

Requires FlexDCA revision A.08.30 and above.
