Mors_live_fitter

Presents a graphical interface for live analyzing the pumping polarization of a magneto-optical resonance signal, where the signal is digitalized using Spectrum M2 digitizer card.

Run "main_window.py" to start the program. It is important to send triggering pulses to the DAQ card in order to receive data as it is programmed:

 def daq_updating(self):
 
        Data.samplerate = self.ui.SamplingRate.value()*1e6
        Data.time = self.ui.SamplingTime.value()*1e-3
        Data.channel = self.ui.Channel.value()
        Data.time_trace=np.array([])
        
        try:
            
            Data.ns = int(Data.time*Data.samplerate)
            
            Data.adc.set_acquisition(channels=[Data.channel], 
                                terminations=["50"], 
                                fullranges=[2],
                                pretrig_ratio=0, 
                                nsamples=Data.ns,
                                samplerate=Data.samplerate)
            

            Data.adc.set_trigger(mode="ext")
            Data.adc.acquire()
            time_trace = Data.adc.acquire()
            Data.ns = int(time_trace.shape[0])
            
            if Data.ns > 0:
                Data.freq = np.fft.fftfreq(Data.ns, d=1/Data.samplerate)[:int(Data.ns/2)]
            
        except:
            print("Check if pulses are sent to the DAQ")
            pass
