[SENSe[1]]|SENSe2:AVERage:SDETect <Boolean>
In AUTO filter mode, the average of the last four values entered into the
filter is compared to the average of the entire filter. If the difference
between the two averages is greater than 12.5%, the digital filter is
cleared. The filter then starts storing new measurements. This feature is
known as step detection and shortens the settling time of the filter when
the input power changes substantially.
Note Step detection is automatically disabled under the following
circumstances:
• TRIG:DEL:AUTO is ON and the trigger mode is set to free run,
or,
• Auto-averaging is disabled.
Under the above circumstances the value of SENS:AVER:SDET is
ignored. Note also that SENS:AVER:SDET is not set by the
instrument (that is, SENS:AVER:SDET will retain its current
setting which may indicate that step detection is ON).
