CALCulate:MEASure:SMOothing Commands

Controls point-to-point smoothing. Smoothing is a noise reduction technique that averages adjacent data points in a measurement trace. Choose the amount of smoothing by specifying either the number of points or the aperture. Smoothing is not the same as CALC:AVERage which averages each data point over a number of sweeps.

CALCulate<cnum>:MEASure<mnum>:SMOothing:APERture <num>

Applicable Models: All

(Read-Write) Sets the amount of smoothing as a percentage of the number of data points in the channel.

Parameters

 

<cnum>

Channel number of the measurement. There must be a selected measurement on that channel. If unspecified, <cnum> is set to 1.

<mnum>

Measurement number for each measurement. There must be a selected measurement on the trace. If unspecified, <mnum> is set to 1.

<num>

Percentage value. Choose any number between:
1 and 25

Examples

CALC:MEAS:SMO:APER 2
calculate2:measure2:smoothing:aperture 20.7

Return Type

Numeric

Default

1.5

CALCulate<cnum>:MEASure<mnum>:SMOothing:POINts <num>

Applicable Models: All

(Read-Write) Sets the number of adjacent data points to average.

Parameters

 

<cnum>

Channel number of the measurement. There must be a selected measurement on that channel. If unspecified, <cnum> is set to 1.

<mnum>

Measurement number for each measurement. There must be a selected measurement on the trace. If unspecified, <mnum> is set to 1.

<num>

Number of points from 1 point to maximum of 25% of data points in the channel. For example: if number of points in a data trace = 401, the maximum value for points = 100. The points value is always rounded to the closest odd number.

Parameters

 

<cnum>

<mnum>

Measurement number for each measurement. There must be a selected measurement on the trace. If unspecified, <mnum> is set to 1.

<bool>

ON or 1 - Turns smoothing ON.
OFF or 0 - Turns smoothing OFF.
