All data will be output in the <NR3> format. (mantissa: max. 4 digits + exponent: 2 digits)
The communication output is set ON by any of the commands starting with
"MEASure:HARMonics:ITEM" and the harmonic measurement data or frequency of PLL source
(SYNChronize) are output according to the following order of priority. Besides, in case of
recalling normal measurement or integration data, the data number will be output in <NR1>
format as well.
(0.Data number in case of recalling)
1.Frequency of PLL source (SYNChronize)
2.VTHD 3.V
8.PF 9.W
Harmonic analysis data will be output for all applicable elements. To find out to which element
the data correspond, use the HARMonics:ELEMent? command.
• Frequency of PLL Source (SYNChronize) : 1 data
Outputs the fundamental frequency (VHZ/AHZ) of the voltage/current for which the PLL source
has been set. The input of the PLL source can be found out using HARMonics:SYNChronize?.
• VTHD,ATHD : 1 data
Outputs the harmonic distortion factor of voltage/current. (for either iEC or CSA). The used
computation method can be found out using the HARMonics:THD? command.
• V,A,W : 51(or 31) data
Rms values of the 1st to 50(or 30)th order→fundamental analysis value (1st order)→harmonic
analysis value (2nd order)→ · · · →harmonic analysis value (50(or 30)th order)
• VCON,ACON,WCON : 49(or 29) data
Harmonic relative content (2nd order)→ · →harmonic relative content (50(or 30)th order)
• PF : 1 data
Outputs the power factor of the fundamental (1st order).
• VDEG : 50(or 30) data
Phase angle between the1st order voltage and 1st order current→Phase angle between the 2nd
order voltage and 1st order voltage→ · · · →Phase angle between the 50(or 30)th order voltage
and the 1st order voltage.
• ADEG : 50(or 30) data
Phase angle between the1st order voltage and 1st order current→Phase angle between the 2nd
order current and 1st order current→ · · · →Phase angle between the 50(or 30)th order current
and the 1st order current.
Each data is divided by a comma "," and ended by the terminator <RMT>.
