24 :MEASure Commands

:MEASure:DUAL:VRMS

(see page 1610)

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
