Hi Steve,
my most recent purchase was a HP 54720D scope and three input amps and active probe. 5 Gsamp/sec so about 1 GHz bandwidth.....The guy I bought it from was a retired HP Engineer and he did a nice job on
it. The thing weighs 70lb and shipping to NZ was going to cost over $1000, got around that by using UPS, no tracking, no insurance, but it got here!
Bought a house since and mortgage has put paid to any plans for more RF gear. In addition now working for a company fixing welding gear, a good percentage of inverter types.
As a consequence I've built up a selection of HV isolated probes, high bandwidth current clamps and a 13kV HF voltage probe. Most of my electronic hobby time seem to be designing
and building wiredrive PCBs, phase controlled bridges to hundreds of amps etc for work related projects. Have had some fun designing and building a servo drive for a decent (2.6kW) AC servo
fitted with an eight pole resolver. All in all a great learning curve. Cheaper than RF too!
