Hey guys,
I am tring to export the fft analysis result from fft tools in power gui to excel. I have 4 input signal available and 3 signal number (i.e. it is a 3 phase sytem with 4 different currents). I tried to export it to MATLAB command window using following command.
FFTDATA = power_fftscope(Currents);
FFTDATA.startTime=0.25;
FFTDATA.cycles = 1;
FFTDATA.fundamental = 50;
FFTDATA.maxFrequency = 2050;
FFTdata.input=3;
>> FFTDATA = power_fftscope(FFTDATA)
FFTDATA =
(%struct with fields:
time: [60001×1 double]
signals: [1×4 struct]
blockName: 'Three_phase_PV_Mod_2018a_correct/Currents'
input: 1%First input
signal: 1% First signal
startTime: 0.2500
cycles: 1
fundamental: 50
maxFrequency: 2050
THDmaxFrequency: Inf
THDbase: 'fund'
freqAxis: 'Hertz'
mag: [41×1 double]
phase: [41×1 double]
freq: [41×1 double]
THD: 8.0498
samplingTime: 5.0000e-06
samplesPerCycle: 4000
DCcomponent: 1.0374
magFundamental: 26.8804)
FFTDATA.mag
FFTDATA.phase
FFTDATA.freq
However, I get magnitude, phase and frequency for 1st input and 1st signal only (as indicated by comment in the result above). How can I get data for other combinations? For example, 2nd signal 3rd inout and so on.
