:MEASure:SDEViation

(see page 658)

Command Syntax

:MEASure:SDEViation [<source>]

<source> ::= {CHANnel<n> | FUNCtion | MATH}

<n>::={1|2|3|4}forthefour channel oscilloscope models

<n> ::= {1 | 2} for the two channel oscilloscope models

The :MEASure:SDEViation command installs a screen measurement and

starts std deviation measurement. If the optional source parameter is

specified, the current source is modified.

Query Syntax

:MEASure:SDEViation? [<source>]

The :MEASure:SDEViation? query measures and outputs the std deviation

of the selected waveform. The oscilloscope computes the std deviation on

all displayed data points.

Return Format

<value> ::= calculated std deviation value in NR3 format
