How comsol Plots Spectrum

1. First of all, we need to draw our own spectrogram and make a spectrogram board according to this picture.

2. Place the corresponding components in AD according to the spectrogram. Remember to create a new project and add SCHdoc and PCBdoc to the project folder. External pins are usually replaced by connectors. After drawing the component connection diagram in AD, click Compile. If there is no error in the circuit, the software will not prompt. After compiling, click the update button in the design to send the component to the PCB file. After AltiumDesignerupdate is completed, you can get the comsol drawing spectrum.
