AM modulation with frecuency sweep

      Hi,

      Working on Circuit Design, I want to perform an Amplitude Modulation using the AMMOD component.


      The waveform I'm looking for at the output has a 80% depth and 1kHz modulation frequency. The carrier wave's frequency starts at 150kHz and ends at 80MHz.

      I'm able to get a correct AM modulation for an stable carrier frequency of 150kHz.

      Hello
      Is there any specific reason you want to define sweep for a carrier frequency? I believe the carrier frequency should be constant for the AM Modulation.

      The output of AMMOD looks good here.

      Thanks Vivek

      Sorry I haven't replied before, I just realized you answered.
      The reason to define a sweep for a carrier frequency is because I want to simulate an generator for the EMC standard EN 61000-4-6. It defines the perturbation in the input of the DUT (Device Under Test) like this, where the carrier wave goes from 150kHz to 80MHz

      Thank you I├▒igo
