The equipment produces amplitude modulation of an internally generated RF carrier by an external audio signal or a locally available DC signal Demodulation can be done by two different types of detectors.

    Modulator Carrier Freq        :  100KHz
    Oscillator                              :  Built-in.
    Types of Amp.Modulation   :  1.DSB withCarrier
                                                   2.DSBS(Supressed carrier)
   T ypes of Detector                 :  1.Diode Type with variableRC(1mS10mS)
                                                   2.Product/SquareLaw detector,local freq 500KHz.
   Local oscillator                      :  Can be locked in phase or can run out of lock  w.r.t.
                                                    500KHz Carrier Oscillator
  Spectrum Analyser                :  Built-in for measurement  & detection of sidebands
                                                    in the modulated signal
 
  The instrument works on 230V + 10%, AC Single Phase

      *  Study of slope distortion caused by excessive time constant in detector circuit.
      *  Measurements of sidebands present in the  modulated signal by spectrum analyser.
      *  Changing the time constant of the detector circuit  and seeing its effect on Modulation

 Economy Model : Amplitude Mod. /Demod. without Product Detector & Spectrum Analyser.
