Hewlett Packard 8551A
|NOTES||An awesome beast from the first half of the 60's. The analyser
consists of two modules, the upper being a (tr*ns*st*r*s*d) display unit
with the lower unit being the buisness end.
How about this for a waveband switch. Any frequency you like as long as it's above a GHz !
With all the equipment in the collection, this has been the only one that I had to take to take apart whilst it was still in the back of the motor as it was too heavy as a single unit.
|SERVICE DATA||No such luck :-(|
|CURRENT STATE||Complete and very clean inside. I gave it to someone who was brave enough to switch it on, and it worked. Well, at least it worked until he sussed out how the thing worked and decided to actually use it on a project, at which point it went bang.|
|WHERE FOUND||Rescued before it
ended up in a skip.
Gawd knows what to do with it ... perhaps someone could persuade me to part with it ?
One of the tuning scales ... in GigaCycles/Second !
|The base unit. AT the top there are lots of mysterious oscillator units, whilst from the underside you can access to a whole bunch of valves|
|The upper display unit. No valves. yawn.|
