CALCulate1:SMOothing:RESPonse
Syntax
CALCulate[1]:SMOothing:RESPonse {SLOW | MEDium | FAST}
CALCulate[1]:SMOothing:RESPonse?
Description
This command selects the number of measurements to be averaged by the moving average (boxcar) filter.
l SLOW selects 100 measurements.
l MEDium selects 50 measurements.
l FAST selects 10 measurements.
Remarks
l The smoothing (moving average) filter produces one result for each measurement made.
l The smoothing (moving average) filter is reset when the measurement function or channel changes, by
INITiate:IMMediate, READ?, and the MEASure? subsystem commands, or if a measurement is outside a
fixed range from the current average. The amount of measurement change required to reset the filter is:
Filter Response Time
Change required to reset
SLOW ±100 ppm
MEDium ±300 ppm
FAST ±1000 ppm
l After the smoothing (moving average) filter is reset, the filter produces results which are the average of
all measurements made after the reset, until the required number of measurements are made as selec-
ted by CALCulate1:SMOothing:RESPonse. Once the required number measurements are made, the res-
ults are the moving average of the last 10, 50, or 100 measurements. Equal weighting is applied to all
measurements used in the average.
l The instrument sets the response time to FAST after a Factory Reset (*RST command) or after an Instru-
ment Preset (SYSTem:PRESet command).
Return Format
The query returns the response time: SLOW, MED, or FAST.
Examples
The following example enables a 50-point moving average filter on 1000 frequency measurements.
