https://www.ebay.com/itm/156452589660Here's a nifty spectrum analyzer, 100 khz to 5.2 ghz at a price most can afford. It is extensively menu driven, quite intuitive, with a manual written by native English speakers. It has many measurement functions beyond simple spectrum analysis and can talk to a PC via USB. A 32 gb tif memory card was included for storage. I bought one of the little 2.8 inch units a few years ago and actually used it on a couple overseas jobs as a sanity check on some other measurements, but this rig works better, has a four color display and my eyes can actually read it. Shipping from China to Maine was 12 days.
I don't understand how they can manufacture and sell these for $130, but I'm glad they do!
