via HACKADAY: Perhaps It’s Time To Talk About All Those Fakes And Clones
A while back, I bought a cheap spectrum analyser via AliExpress. I come from the age when a spectrum analyser was an extremely expensive item with a built-in CRT display, so there’s still a minor thrill to buying one for a few tens of dollars even if it’s obvious to all and sundry that the march of technology has brought within reach the previously unattainable. My AliExpress spectrum analyser is a clone of a design that first appeared in a German amateur radio magazine, and in my review at the time I found it to be worth the small outlay but a bit deaf and wide compared to its more expensive brethren.
