20 :MEASure Commands

:MEASure:SDEViation

(see page 798)

Command Syntax

:MEASure:SDEViation [<source>]

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

<n> ::= 1-2 or 1-4 (# of analog channels) in NR1 format

<r> ::= 1-2 in NR1 format

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

• ":MEASure:VRMS" on page 392

• ":MEASure:SOURce" on page 380

NOTE

This ":MEASure:VRMS DISPlay, AC" command is the preferred syntax for making standard

deviation measurements.

NOTE

This command is not available if the source is FFT (Fast Fourier Transform).
