A reset (*RST), instrument preset (SYSTem:PRESet), or changing the mea-
surement function disables the CALCulate1 subsystem.
Smoothing Data
Measurements can be “smoothed” and scaled prior to performing math opera-
tions on the incoming data.
To reduce random noise, a moving average (boxcar) filter can be inserted into
the data path (Figure 6-1). To enable the filter and specify the number of read-
ings (subset) to average, the following commands are used:
CALCulate[1]:SMOothing[:STATe] {OFF|ON}
CALCulate[1]:SMOothing[:STATe]? (query form)
CALCulate[1]:SMOothing:RESPonse {SLOW|MEDium|FAST}
CALCulate[1]:SMOothing:RESPonse? (query form)
ON enables the moving average filter - placing it in the data path. OFF disables
the filter. A reset (*RST) or instrument preset (SYSTem:PRESet) disables the
filter.
