:CALCulate3 Subsystem

 

 

This subsystem performs post-acquisition statistics computation and data transfer.

 

Not until :CALCulate3:LFILter:STATe is set to ON will any of the

NOTE

 

 

 

:CALCulate3:LFILter settings be used.

 

 

Not until :CALCulate3:AVERage[:STATe] is set to ON will any of the

 

 

:CALCulate3:AVERage settings be used.

 

 

 

The statistics results are unaffected by post-processing invoked with :CALC[12]:IMM.

:CALCulate3:AVERage Subtree

This subtree collects together the commands associated with the statistics capabilities.

The statistics results combine successive measurements to produce a composite result

Not until :CALCulate3:AVERage[:STATe] is set to ON will any of one :CALCulate3:AVERage settings be used.

:CALCulate3:AVERage:ALL?

This query returns all four statistics (i.e., mean , standard deviation, maximum , and minimum ).

Statistics should be enabled (:CALC3:AVER[:STATe] ON) before attempting to query results.

Query Response ∙ Numeric data transferred as ASCII bytes in <NR3> format.

The number of significant digits will range from 1 to 15, depending on the measurement resolution.

∙ Numbers are separated by commas. The ordering of numbers within the response is mean, standard deviation, minimum,

and maximum.

∙ If :CALC3:AVER[:STATe] is OFF, four comma-separated Not a Number 9.91E37 values are returned and error -221 is generated.

∙ If no valid result exists, four comma-separated Not a Number 9.91E37 values are returned and error -230 is generated.
