:MEASure:TDEQ:PRESets
Command Syntax
:MEASure:TDEQ:PRESets <preset name>
<preset name> is a string.
Query Syntax
:MEASure:TDEQ:PRESets?
Description
Loads a previously saved settings, known as a preset, for a :MEASure:EYE:TDECQ measurement. The preset configures the measurement to your saved settings. To query which presets are available for loading, use the :PRESet:SELections? query.

The preset includes the settings made with the following sibling commands:
- :MEASure:TDEQ:HWIDth (histogram width)
- :MEASure:TDEQ:TSER (target Symbol Error Rate)
Presets can only be saved from the measurements Setup dialog. There is no programming command for this task.
Requires FlexDCA revision A.05.60 and above.
Example Commands
:MEASure:TDEQ:PRESet "MyPreset" // Load your saved preset. :MEASure:TDEQ:PRESet:SELections? // Get list of saved presets.
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?.
