HARMonics Group

The commands in this group deal with harmonic measurement.
You can make the same settings and queries that you can make by pressing HRM SET on the front panel.
The commands in this group are only valid on models with the simultaneous dual harmonic measurement (/G6) option
or the harmonic measurement (/G5) option.
:HARMonics<x>?
Function Queries all harmonic measurement settings.
:HARMonics<x>?
Syntax
<x> = 1 or 2 (harmonic measurement
group)
Description "HARMonics2" is only valid on models with the
simultaneous dual harmonic measurement (/G6)
option.
:HARMonics<x>:CONFigure?
Function Queries the harmonic measurement groups of all
elements.
:HARMonics<x>:CONFigure?
Syntax
Description • This command is only valid on models with
the simultaneous dual harmonic measurement
(/G6) option.
• The <x> value in HARMonics<x> has no
meaning in the query.
:HARMonics<x>:CONFigure[:ALL]
Function Collectively sets the harmonic measurement
group of all elements.
:HARMonics<x>:CONFigure[:ALL]
Syntax
{<NRf>}
<NRf> = 1 (Hrm1), 2 (Hrm2)
:HARMONICS:CONFIGURE:ALL 1
Example
Description • This command is only valid on models with
the simultaneous dual harmonic measurement
(/G6) option.
• The <x> value in HARMonics<x> has no
meaning in the setting.
:HARMonics<x>:CONFigure:ELEMent<x>
Function Sets or queries the harmonic measurement group
of the specified element.
:HARMonics<x>:CONFigure:
Syntax
ELEMent<x> {<NRf>}
:HARMonics<x>:CONFigure:ELEMent<x>?
ELEMent<x>'s <x> = 1 to 6 (element)
<NRf> = 1 (Hrm1), 2 (Hrm2)
:HARMONICS:CONFIGURE:ELEMENT1 1
Example
:HARMONICS:CONFIGURE:ELEMENT1? ->
:HARMONICS1:CONFIGURE:ELEMENT1 1
Description • This command is only valid on models with
the simultaneous dual harmonic measurement
(/G6) option.
• The <x> value in HARMonics<x> has no
meaning in the setting or query.
IM WT1801-17EN
:HARMonics<x>:CONFigure:
{SIGMA|SIGMB|SIGMC}
Function Collectively sets the harmonic measurement
group of all the elements that belong to the
specified wiring unit (ΣA, ΣB, or ΣC).
:HARMonics<x>:CONFigure:
Syntax
{SIGMA|SIGMB|SIGMC} {<NRf>}
<NRf> = 1 (Hrm1), 2 (Hrm2)
:HARMONICS:CONFIGURE:SIGMA 1
Example
Description • This command is only valid on models with
the simultaneous dual harmonic measurement
(/G6) option.
• The <x> value in HARMonics<x> has no
meaning in the setting.
:HARMonics<x>:ORDer
Function Sets or queries the maximum and minimum
harmonic orders that are analyzed.
:HARMonics<x>:ORDer {<NRf>,<NRf>}
Syntax
:HARMonics<x>:ORDer?
<x> = 1 or 2 (harmonic measurement
group)
First <NRf> = 0 or 1 (minimum
harmonic order that is analyzed)
Second <NRf> = 1 to 500 (maximum
harmonic order that is analyzed)
:HARMONICS:ORDER 1,100
Example
:HARMONICS:ORDER? ->
:HARMONICS1:ORDER 1,100
:HARMonics<x>:PLLSource
Function Sets or queries the PLL source.
:HARMonics<x>:PLLSource {U<x>|I<x>|
Syntax
EXTernal}
:HARMonics<x>:PLLSource?
HARMonics<x>'s <x> = 1 or 2 (harmonic
measurement group)
U<x> and I<x>'s <x> = 1 to 6 (element)
EXTernal = External clock input (Ext Clk)
:HARMONICS:PLLSOURCE U1
Example
:HARMONICS:PLLSOURCE? ->

:HARMonics<x>:THD
Function Sets or queries the equation used to compute the
THD (total harmonic distortion).
:HARMonics<x>:THD {TOTal|FUNDamental}
Syntax
:HARMonics<x>:THD?
<x> = 1 or 2 (harmonic measurement
group)
