Calculating the Mean Value, Standard Deviation, and p-p of the Trace

Other topics about Analysis and Processing of Result

Overview

You can easily determine the statistics data for a trace (span, mean, standard deviation, and peak-to-peak). The definitions for the statistics data elements are shown below. It is calculated within the range of markers 1 and 2. The markers 1 and 2 are activated automatically.

Statistics data element

Definition

Span

Span between markers 1 and 2.

Mean (mean)

(n: number of points between markers 1 and 2; xi: measured value at the i-th measurement point between markers 1 and 2.)

Standard deviation

(s. dev)

(n: number of points between markers 1 and 2; xi: measured value at the i-th measurement point between markers 1 and 2; mean: Mean)

Peak-to-peak (p - p)

Max - Min

(Max: greatest measured value between markers 1 and 2.; Min: smallest measured value between markers 1 and 2.)

Displaying Statistical Data

  1. Press Channel Next (or Channel Prev) and Trace Next (or Trace Prev) to activate the trace of which the statistical data is required.

  2. Press Marker Fctn > Statistics to turn ON the display of statistics data.

  3. The markers 1 and 2 are activated automatically. Move markers 1 and 2 to the position of the measurement.
