Keysight 53230A - Calculate1:Average:adeviation

CALCulate1:AVERage:ADEViation?
Syntax
CALCulate[1]:AVERage:ADEViation?
Description
This query returns the Allan deviation of all measurements taken since the last time statistics were
cleared.
Remarks
l Allan deviation is only computed when the measurement function is frequency or period.
l For a true Allan deviation computation, continuous gap-free measurement mode should be selected
(SENSe:FREQuency:MODE CONTinuous set).
l You can read the statistical values at any time.
l The instrument clears the statistical values when CALCulate1:AVERage:STATe ON is sent, when the
measurement function is changed, when the INITiate:IMMediate, MEASure? or READ? commands are
executed, when the CALCulate1:AVERage:CLEar command is executed, after a Factory Reset (*RST
command) or after an Instrument Preset (SYSTem:PRESet command).
Return Format
The query returns the Allan deviation of the measurements taken in the form
+1.34892723498343E+001.
Examples
The following example returns the Allan deviation of 100 frequency measurements.
