CALCulate:SMOothing Subsystem
This subsystem controls the smoothing (moving average) filter. This subsystem applies only to the
34465A and 34470A.
Command Summary
CALCulate:SMOothing:RESPonse
CALCulate:SMOothing[:STATe]
CALCulate:SMOothing:RESPonse {SLOW|MEDium|FAST}
CALCulate:SMOothing:RESPonse?
Selects the number of measurements to be averaged by the moving average (boxcar) filter.
{SLOW|MEDium|FAST} SLOW = 100 measurements, MEDium = 50 meas-
urements, FAST = 10 measurements. Default: 10 measurements.
Enable a 50-point moving average filter on 1000 measurements:
CONF:VOLT 10
SAMP:COUN 1000
CALC:SMO:RESP MED
CALC:SMO:STAT ON
CALC:STAT ON
READ?
Typical Response: +9.99383828200000E+00,+9.99352315400000E+00,... (1000 measurements)
Applies only to the 34465A and 34470A.
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 changes, by
l
ate:IMMediate, READ?, or MEASure?, or if a reading is too far beyond the current average.
After the smoothing (moving average) filter is reset, the filter produces results which are the average
l
of all measurements made after the reset, until the required number of measurements are made as
selected by CALCulate:SMOothing:RESPonse. Once the required number measurements are made,
the results are the moving average of the last 10, 50, or 100 measurements. Equal weighting is
applied to all measurements used in the average.
The instrument sets the response time to FAST after a Factory Reset
l
Preset (SYSTem:PRESet).
