The frequency range needed makes (calibrated) equipment expensive. Loaded Raptor expensive! Grin. Either way, thanks for it! Mounting my detector later today.
Among other electronics I have been collecting test equipment, including microwave stuff, for a few decades. While some of my hardware may not have fancy readouts and displays (and other of my stuff does) there is no reason it can't be used. We did measurements just fine before digital was a thing. You can pick up a good, working, sig gen up to 12+ GHz for a couple hundred bucks, if you don't mind analog readouts, and digital up to 20 GHz for a few thousand or less.
Calibration is not really an issue. To measure relative attenuation, such as through the glass and sun screen, all you need is a known step value, lets say a single calibrated 3 dB attenuator. It has been a number of years since any of my equipment was sent anywhere for calibration, but with a little work you can periodically check the calibration yourself. So while it may not be NIST traceable my equipment is generally pretty good in amplitude and frequency. As long as I have confidence in my power meter and freq meter I can easily calibrate everything else myself. I have the equipment to do X and K band myself, but Ka is above my hardware. I have feedhorns for that band (Ka), but my spec an and sig gen don't go up there (had to use other peoples equipment for that band). And to get K band I use a doubler on my sig gen.
But through my employer I have access to anything I need up to 40+ GHz, and calibrated. We do this professionally. So really not an issue
(edit) I just noticed you have "HF/VHF/UHF" in your sig. What is your setup? In the Raptor I have a Kenwood TS2000 with RC2000 control head. So yes, HF/VHF/UHF for me also.
T!
