Communication Commands
6.10 HARMonics Group
The commands in this group deal with harmonic measurement.
You can make the same settings and inquiries as when the HRM SET on the front panel is used.
However, the commands in this group are valid only when the advanced computation function (/G6 option) is installed.
:HARMonics?
Function
Queries all settings related to harmonic
measurement.
Syntax
:HARMonics?
Example
HARMONICS? -> :HARMONICS:
FBAND NORMAL;PLLSOURCE U1;
ORDER 1,100;THD TOTAL;IEC:
OBJECT ELEMENT1;UGROUPING OFF;
IGROUPING OFF;:HARMONICS:
PLLWARNING:STATE 1
:HARMonics:FBANd
Function
Sets the frequency bandwidth of the harmonic
measurement or queries the current setting.
Syntax
:HARMonics:FBANd {NORMal|WIDE}
:HARMonics:FBANd?
Example
:HARMONICS:FBAND NORMAL
:HARMONICS:FBAND? ->
:HARMONICS:FBAND NORMAL
Description • This command is valid only on models with the
advanced computation function (/G6 option).
• For details on the frequency bandwidth
corresponding to
{NORMal|WIDE}

:HARMonics:IEC?
Function
Queries all settings related to IEC harmonic
measurement.
Syntax
:HARMonics:IEC?
Example
:HARMONICS:IEC? -> :HARMONICS:IEC:
OBJECT ELEMENT1;UGROUPING OFF;
IGROUPING OFF
Description This command is valid only on models with the
advanced computation function (/G6 option).
:HARMonics:IEC:OBJect
Function
Sets the IEC harmonic measurement target or
queries the current setting.
Syntax
:HARMonics:IEC:OBJect {ELEMent<x>|
SIGMA|SIGMB}
:HARMonics:IEC:OBJect?
<x> = 1 to 4 (element)
Example
:HARMONICS:IEC:OBJECT ELEMENT1
:HARMONICS:IEC:OBJECT? ->
:HARMONICS:IEC:OBJECT ELEMENT1
Description This command is valid only on models with the
advanced computation function (/G6 option).
:HARMonics:IEC:{UGRouping|IGRouping}
Function
Sets the {voltage|current} grouping of the IEC
harmonic measurement or queries the current
setting.
Syntax
:HARMonics:IEC:{UGRouping|
IGRouping} {OFF|TYPE1|TYPE2}
:HARMonics:IEC:{UGRouping|
IGRouping}?
Example
:HARMONICS:IEC:UGROUPING OFF
:HARMONICS:IEC:UGROUPING? ->
:HARMONICS:IEC:UGROUPING OFF
Description • This command is valid only on models with the
advanced computation function (/G6 option).
• For details on the grouping corresponding to
{OFF|TYPE1|TYPE2}

.
:HARMonics:ORDer
Function
Sets the maximum and minimum orders to be
measured or queries the current setting.
Syntax
:HARMonics:ORDer {<NRf>,<NRf>}
:HARMonics:ORDer?
1st <NRf> = 0 or 1 (minimum order to be
measured)
2nd <NRf> = 1 to 100 (maximum order to be
measured)
Example
:HARMONICS:ORDER 1,100
:HARMONICS:ORDER? -> :HARMONICS:ORDER
1,100
