Hey Dave, you might consider attenuating your signal to -30dbm. A lot of spectrum analyzers start to get over loaded as you go above that. I haven't used this particular model, but you will probably have a better/truer display of the signal.
Hey Dave, How about a clickable list of accessories that don’t cost as much as the spectrum analyzer? Things like cables, attenuators, and adapters. The Rigol branded ones seem so expensive. Thanks
As I am sure you know all periodic signals can be represented by an infinite summation of sin waves hence this might be a great opportunity to introduce the Fourier series. I think it really drives home why a nonlinear signal splatters across the band and why filtering is so important.
Maybe tune a couple cans to use as a cavity filter? There's even some plans to make your own fur UHF out of coffee cans out there somewhere if you want to homebrew them.
There's an explanation in the Tech series videos. Basically, a harmonic is a frequency that is an integer multiple (2, 3, 4, etc.) of the fundamental frequency. Generally we try to suppress harmonics as they are undesirable.
David Casler lucky duck getting that one very good Dave. Looking forward to seeing you get on the top band. Looks like you have enough to get a full size 160 up 😉 KC3ONO
