Was that by any chance the R&S AMIQ that I refurbished in an earlier blog post?
replyAnd yes, it's a lot of fun bringing these bargain bin pieces of kit back to life.
My model is an SMIQ03E actually! I've grown quite addicted to going to my local 2nd hand electronics store in recent months scrounging for anything with an rs232 port!
replyI looked for a SMIQ for quite a while to go along with the AMIQ, but eventually settled for the R&S SFQ TV test transmitter that you can see here: https://tomverbeure.github.io/2026/06/28/Rohde-Schwarz-AMIQ-....
replyIt can be used a vector RF signal generator with I/Q inputs. The only limitation is the reduced input bandwidth.
Very cool! Yeah I lucked out finding mine. It was in the intake section at my 2nd hand electronics store. It had a broken power button so they were selling it "as-is". A button repair and battery swap later I have a 3.3Ghz VNA. Can't complain!
replyThat's a great find, but afaict that model doesn't have VNA capabilities, does it? However, if you also stumble on a spectrum analyzer at that second hand store, you could combine them into a scalar network analyzer.
replyOops yeah you're right, it's a VNG. A VNA would be great to have though! I wonder if these agents are going to just increase the utility of ever piece of equipment people can hook them to.
