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.
