:MEASure Commands
:MEASure:DUAL:VRMS
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><NL>
<value> ::= calculated dc RMS value in NR3 format
