my new old toy is a Rohde+Schwarz Polyskop 3 TYPE Swob
The sweeper is full loadet (10x oscillator plugin) so it goes 100kHz up to 1GHz.
The Screen is like a TV Tube, but P7 phosphor.
There is no tubes inside, a cold machine, but still a boatanchor of 42kg.
I got him including his adapters..
Congratulations for getting such a nice unit!
Some years ago I got also a SWOB III along a collection of RF probes, manuals and such. But I have not yet powered it up!!! (I have always too many projects going
BTW, my unit has different plug-ins than yours... I will check on return home.
Someday I will power it up
