:MEASure:LLINe:MLOCation?
Query Syntax
:MEASureN:MLOCation?
Where N identifies one of 64 {1:64} possible limit line tests. For example, :LLINe23.
Description
Queries the location in time of the data point where the pass/fail margin is reported for a Limit Line Test. The returned time value is the same value that is shown in the displayed Limit Lines panel. To return the pass/fail margin, use the :MEASuer:LLINe:MARGin? query. To return the total number of failed data points for the Limit Line Test, use the :MEASure:LLINe:FPOints? query. To load and display a Limit Line Test, use the :LLINe:DISPlay command.
Only displayed data points are analyzed. For example, if you zoom in on the waveform so that a portion of the Limit Line Test is off screen, any failed data point that exists off screen will not be analyzed.
Requires FlexDCA revision A.04.50 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?.
