:MEASure:VAVerage

(see page 750)

Command Syntax

:MEASure:VAVerage [<interval>][,][<source>]

<interval> ::= {CYCLe | DISPlay | AUTO}

<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:VAVerage command installs a screen measurement and

starts an average value measurement. If the optional source parameter is

specified, the current source is modified.

Query Syntax

:MEASure:VAVerage? [<interval>][,][<source>]

The :MEASure:VAVerage? query returns the average value of an integral

number of periods of the signal. If at least three edges are not present, the

oscilloscope averages all data points.

The :MEASure:VRMS? query returns the average value of the selected

waveform. How the average value is measured depends on the <interval>

specification:

• If <interval> is CYCLe, the average value is measured on an integral

number of periods of the displayed signal. If less than three edges are

present, the measurement fails, and +9.9E+37 is returned.

• If <interval> is DISPlay, the average value is measured on all displayed

data points.

• If <interval> is AUTO or is not specified, the measurement attempts to

compute a value using the CYCLe interval. If less than three edges are

present, the measurement is computed using the DISPlay interval.

Return Format

<value> ::= calculated average value in NR3 format
