:MEASure Commands

:MEASure:SDEViation

Command Syntax
:MEASure:SDEViation [<source>]
<source> ::= {CHANnel<n> | FUNCtion<m> | MATH<m> | WMEMory<r>}
<n> ::= 1-2 or 1-4 (# of analog channels) in NR1 format
<m> ::= 1-4 in NR1 format
<r> ::= 1 to (# ref waveforms) in NR1 format
This ":MEASure:VRMS DISPlay, AC" command is the preferred syntax for making standard
N O T E
deviation measurements.
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.
This command is not available if the source is FFT (Fast Fourier Transform).
N O T E
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><NL>
<value> ::= calculated std deviation value in NR3 format
