Calculate: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.

Critical Note: CALCulate commands act on the selected measurement. You can select one measurement for each channel using Calc:Par:MNUM or Calc:Par:Select. Learn more.
CALCulate<cnum>:SMOothing:APERture <num>
(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. |
<num> |
Percentage value. Choose any number between: 1 and 25 |
Examples |
CALC:SMO:APER 2 calculate2:smoothing:aperture 20.7 |
Query Syntax |
CALCulate<cnum>:SMOothing:APERture? |
Return Type |
Numeric |
1.5 |
|
CALCulate<cnum>:SMOothing:POINts <num>
(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. |
<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. |
