Use Real-Time Spectrum Analysis to Characterize a transmitter key-up

You sir are very lucky to have access to such nice equipment.

I feel so inadequate with my Motorola Service monitor.

Thanks for taking the time in making this video.

@radiotech181 Yes - I AM very lucky to have access to these awesome tools! Pretty amazing what you can do with them. Of course, I don't have a service monitor - and I'd like to have one of them someday.

You have way too much Tektronix gear. :)

@thewii552 That's what happens when your lucky enough to work for Tektronix. The scopes in the other videos are mine, but the real-time spectrum analyzer used in this video belongs to Tek.

Ever work with the RF Hawk? That is one sweet looking piece of technology.

@supertruckertom Yes, I have worked with the RFHawk. It is one of the "toys" in my inventory...

Huh, we were doing this almost 20 years ago in Philadelphia to prevent the rif-raf from using some of the VHF repeaters.

@rdarlington Very good. Of course, there's nothing new about this technique of tx identification, especially at these narrow bandwidths. We used to do it by scoping the FM detector output of a scanner or similar receiver. Today's technology, that didn't exist 20yrs ago, brings nearly 300,000 spectrums/second across bandwidths to 110MHz including frequency domain and spectral density triggering, with high dynamic range seamless wideband capture for extended periods of time. Fun stuff!
