Extremely good deals are rare and the chance that there’s something broken is very real. I often consider that a feature: fixing test equipment is a bit of a hobby, but be prepared to end up with a doorstop that cost a few hundred dollars.
Here are some examples that I bought though them:
- HP 8650E spectrum analyzer: works but intermittent shutdowns
- TDS 794D: works, but CRT is broken. A well know failure mode. Need to install a $75 LCD replacement.
- this R&S AMIQ: totally broken. Needed many days of work to revive.
