I'm sitting here looking at an instrument that blows my mind. It is a miniature had held spectrum analyser that sweeps from 100 KHz to 12 Ghz. 12 Ghz! I'm looking at the WiFi channel at 2.54 GHz with a waterfall display. Sure, it doesn't have the dynamic range of a R&S, but it doesn't cost as much either. It is good enough for my purposes. I have recently collected a respectable group of test equipment for not much dinero that anyone can enjoy. All prices are in CAD: Knadgbft Ultra 4Inch Spectrum Analyzer Ultra 100KHz-12GHz $215.35 https://www.amazon.ca/dp/B0CLV1KJCR Nanovna 10KHz-1.5Ghz Vector Network Analyzer $72.99 https://www.amazon.ca/10KHz-1-5Ghz-Analyzer-Measuring- Parameters-Standing/dp/B07X1PL6RH/ SIGLENT SDG1062X Function/Arbitrary Waveform Generator 2 Channels 60 MHz 150 MSa/s $681.50 https://www.amazon.ca/dp/B06WWPTSXW Siglent Technologies SDS1202X-E 200 mhz Digital Oscilloscope 2 Channels $525.05 https://www.amazon.ca/gp/product/B06XZML6RD/ For those interested in wideband reception, there are an enormous amount of articles on discone antennas that can go from 25MHz to 2GHz. Here is one: Have You Thought of a Discone (#809) https://www.youtube.com/watch?v=zOLDrOp43Nw The Nanovna might be useful to tune these antennas. -- MRM

LNBs make great downconverters... https://panteltje.nl/pub/testing_LNBs_IMG_6772.JPG

It says up to 12 GHz it can observe signals. The signal generator is nice too. I used a Raspberry Pi as signal generator at times: https://panteltje.nl/panteltje/newsflex/download.html#freq_pi And an ADF4350 evaluation board, also from ebay: https://panteltje.nl/panteltje/newsflex/download.html#ADF4350_test More stuff on my site via that link...>Group io has a forum for it. https://groups.io/g/tinysa/topicsCool, I am subscribed to an other groups_io group: GammaSpectrometry>There are several models and makers of the NanoVna.

Have to read up on those sites...
