:MEASure:HISTogram:SCALe?
Query Syntax
:MEASURE:HISTogram{1:4}:SCALe?
Description
Returns the scale used to display the histogram, which is the number of hits per major graticul division. It is the Peak Hits divided by the histogram size. For vertical histograms, size is set by the :HISTogram:VSIZe command. For horizontal histograms, size is set by the :HISTogram:HSIZe command. This value is not reported on the Histograms results table.
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?.
