Determining Mean, Standard Deviation, and Peak-to-Peak of the Trace

Other topics about Data Analysis

You can easily determine the statistics data for the trace between bandmarkers (mean, standard deviation, and peak-to-peak). The following figure and table show the definitions for the statistics data elements.

Parameters Used for Calculating Statistics Data

Statistics data element

Definition

Average
(Mean)


(n: number of points; xi: i measured value at the i-th measurement point)

Standard deviation
(S. Dev)

(n: number of points; xi: measured value at the i-th measurement point; mean: mean)

Peak-to-
Peak (PtoP)

Max - Min

(Max: greatest measured value; Min: smallest measured value)

 

 

Specifying Range for Statistical Data

  1. Press Trace Next or Trace Max to activate the trace for which you want to obtain statistical data.

  2. Press Marker Fctn > Analysis Range (X).

  3. Press Marker Fctn > Analysis Range (Y)

Specify the range (X/Y-Axis) from which you want to obtain statistical data.

Analysis Range

Description

Full Range
(Fullscale)

Statistical data are obtained from all traces.

Bandmarker
(Bandmarker)

Statistical data are obtained from within bandmarker.

To set up the bandmarker, refer to Setting Search Range (Bandmarkers).

Displaying Statistical Data

  1. Press Trace Next or Trace Max to activate the trace for which you want to obtain statistical data.

  2. Press Marker Fctn.

  3. Specify the range (X/Y-Axis) from which you want to obtain statistical data. For more information, refer to Specifying Range for Statistical Data.

  4. Set the Analysis Type to Integral | Statistics | Linear Regression.
