CALCulate[1]:AVERage:STATe {OFF|ON}
CALCulate[1]:AVERage[:STATe]? (query form)
ON - enables statistical calculations on the readings as they occur. Statistical
data includes: mean, standard deviation, Allan deviation, maximum value,
minimum value, and average peak-to-peak value.
OFF - disables statistics computation.
Following a reset (*RST) or instrument preset (SYSTem:PRESet), statistical
computations are disabled.
Reading Count
Statistical calculations start when Math and the Statistics function are enabled.
The number of readings on which a given set of statistics are based is shown as
the Count value (Figure 6-3). The count can also be queried with the command:
CALCulate[1]:AVERage:COUNt:CURRent?
The count can be read at any time after the measurements have been initiated
(i.e. INITiate:IMMediate, READ?, MEASure?).
Following a reset (*RST) or instrument preset (SYSTem:PRESet), the count is
set to ‘1’.
Mean, Standard Deviation, Minimum Value, Maximum Value
The mean (average), standard deviation, minimum value, and maximum value
for the current reading count can be determined with the command:
CALCulate[1]:AVERage:ALL?
If the readings have been scaled (see “Scaling Functions”), the statistics are
based on the scaled readings.
