Spectrum Depends Upon Frequency and Rise/Fall Time
Per hackaday: https://hackaday.com/2024/03/30/how-much-bandwidth-does-cw-really-occupy/ and https://www.youtube.com/watch?v=KEgrTwjWLf0 Ideally a spectrum analyzer will look at both the spectrum and the waveform (oscilloscope), the latter being used for rise/fall time. Also worth noting is the old adage about square waves being made up of sine waves. There are a number of youtube videos on that.
