:MEASure:MTESt:MARGin?
Query Syntax
:MEASure:MTESt{N}:MARGin?
{N} identifies a specific mask and must be a value from 1 to 16. For example, :MTESt2: selects mask 2.
Description
Returns the mask Margin definition in the Masks Tests results table during eye mask testing. This is the ratio of margin area to the standard mask area expressed as a percentage. This value is negative for negative mask margins that encroach on the area of the standard mask or positive for positive mask margins that expand the area of the mask. To set the mask margin, use the :MTESt:MARGin:PERCent command.
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?.
