Query Format
MEASure:SPECTrum:CURRent#[:MAGnitude]?
Description
Returns harmonics spectrum for current 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
harmonic, etc. Values represent % of
fundamental (relative).
Only a single spectrum may be queried in a command.
Returned Data Format
<nr2>, <nr2>, <nr2>,……, <nr2>
Query Example
MEAS:SPECT:CURR1?
4.6300, 0.001, 0.23…., 0.000
Command Syntax
MEASure:SPECTrum:PHASe:REFerence
Description
This command sets the phase reference for the harmonic analysis
measurement function.
Parameters
Available settings are:
0
None.
1
(DEFAULT) All phases measurements are referenced to
phase A voltage.
2
Voltage and current phases measurements are referenced
to the voltage of the same phase (A, B or C)
3
Voltage phase measurements are referenced to the voltage
of the same phase (A, B or C).
Current phase measurements are referenced to the current
of the same phase (A, B or C)

2
Query Format
MEASure:SPECTrum:PHASe?
Description
Returns phase angles in degrees for the most recent voltage or
current spectrum query. Returns a data set of 51, <nr2> type
numbers, comma delimited. The 1
st
element is the phase angle of the
fundamental, for reference. The 2
nd
element is the phase angle of the
2
nd
harmonic, etc.
Returned Data Format
