:MEASure Commands 20

Agilent InfiniiVision 3000 X-Series Oscilloscopes Programmer's Guide 423

:MEASure:DUAL:VRMS

(see page 1138)

Overview This measurement is available with the N2820A high sensitivity current

probe when both the Primary and Secondary probe cables are used. This

measurement joins the Zoom In waveform data below the probe's clamp

level with Zoom Out waveform data above the probe's clamp level to create

the waveform on which the measurement is made.

Command Syntax

:MEASure:DUAL:VRMS [<interval>][,<type>][,<source1>][,<source2>]

<interval> ::= {CYCLe | DISPlay}

<type> ::= {AC | DC}

<source1>,<source2> ::= CHANnel<n> with N2820A probe connected

<n> ::= 1 to (# analog channels) in NR1 format

The :MEASure:DUAL:VRMS command installs a screen measurement and

starts an RMS value measurement.

The <interval> option lets you specify the measurement interval: either an

integral number of cycles, or the full screen. If <interval> is not specified,

DISPlay is implied.

The <type> option lets you choose between a DC RMS measurement and

an AC RMS measurement. If <type> is not specified, DC is implied.

If the optional source parameter(s) are specified, the currently specified

source(s) are modified.

Query Syntax

:MEASure:DUAL:VRMS? [<interval>][,<type>][,<source1>][,<source2>]

The :MEASure:DUAL:VRMS? query measures and outputs the RMS value

measurement.

Return Format

<value> ::= calculated dc RMS value in NR3 format
