Query Syntax

:MEASure:LTESt:MLIMit{1:16}:FAILures?

{1:16} identifies a Limit Line Test.

Description

Queries the number of failures reported for a measurement limit test. To query the number of waveforms acquired, use the :MEASure:LTESt:MLIMit:WAVeforms? query. Use the :LTESt:MEASure:MLIMit:STATe command to turn on a measurement limit test.

Requires FlexDCA revision A.04.00 and above.

Measurement Ready?

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

if ('CORR' in Flex.query(':STATus?')):
	measurement = Flex.query('?')

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 (:COUNt?). The technique uses the :COUNt? common measurement query. For example,

if (Flex.query(':COUNt?') >= Flex.query(':ACQuire:ECOUNt?')):
	measurement = Flex.query('?')

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?.
