CHANnel<m>:ARIThmetics
<TrArithmetic>
Selects the method to build the resulting waveform from several consecutive acquisitions
of the signal.
Suffix:
<m>
.
The command affects all channels regardless of the indicated
channel number. The suffix can be omitted.
Parameters:
<TrArithmetic>
OFF | ENVelope | AVERage | SMOoth | FILTer
OFF
The data of the current acquisition is recorded according to the
decimation settings.
ENVelope
Detects the minimum and maximum values in an sample interval
over a number of acquisitions.
AVERage
Calculates the average from the data of the current acquisition and
a number of acquisitions before. The number of used acquisitions
is set with
SMOoth
Calculates a mean value of several adjacent sample points. Thus,
smoothing is a moving average that uses the full data and can be
used for non-periodic signals. It works like a low-pass, and increa-
ses the vertical resolution at the expense of bandwidth reduction.
FILTer
Sets a low-pass filter with 3 db attenuation at a configurable limit
frequency set with
. The filter
removes higher frequencies from the channel signals.
