Data Format of Harmonic Measurement
All data will be output in the <NR3> format. (mantissa: max. 5 exponent: 2
digits)
Output Format of Harmonic Measurement
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 4.VCON 5.ATHD 6.A 7.ACON
8.PF 9.W 10.WCON 11.VDEG 12.ADEG
Harmonic measurement 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 measured value (1st
order)
→
harmonic measurement value (2nd order)
