AFX Series Power Source Operation Manual
MEASure:SPECTrum:VOLTage#[:MAGnitude]?
Returns harmonics spectrum for voltage on selected phase #. # = 1, 2
or 3. Returns a data set of 51, <nr2> type numbers, comma delimited.
The 1 st element is the magnitude of the fundamental, for reference.
The 2 nd element is the 2 nd
fundamental (relative).
Only a single spectrum may be queried in a command.
<nr2>, <nr2>, <nr2>,......, <nr2>
MEAS:SPECT:VOLT1?
100.000, 0.001, 0.3...., 0.000
MEASure:SPECTrum:VLL#[:MAGnitude]?
Returns harmonics spectrum for three phase Line to Line voltage on
selected phase #. # = 1, 2 or 3 (1 = Vab, 2 = Vbc, 3 = Vac). Returns a
VLL data set of 51, <nr2> type numbers, comma delimited. The 1
element is the magnitude of the fundamental, for reference. The 2
element is the 2 harmonic, etc. Values represent % of fundamental
nd
(relative).
Only a single spectrum may be queried in a command.
<nr2>, <nr2>, <nr2>,......, <nr2>
MEAS:SPECT:VLL1?
207.000, 0.001, 0.3...., 0.000
MEASure:SPECTrum:VLL#:ABSolute?
Returns absolute harmonics spectrum for three phase Line to Line
voltage on selected phase #. # = 1, 2 or 3 (1 = Vab, 2 = Vbc, 3 = Vac).
Returns a VLL data set of 51, <nr2> type numbers, comma delimited.
The 1 st element is the magnitude of the fundamental, for reference.
The 2 nd element is the 2 nd
fundamental (relative).
Only a single spectrum may be queried in a command.
<nr2>, <nr2>, <nr2>,......, <nr2>
MEAS:SPECT:VLL1:ABS?
207.000, 0.001, 0.3...., 0.000
