Keep an eye open on Ebay for a Heathkit IG4505 and you can do it reasonably well with that without all other expensive kit provided you don't require it to be calibrated to Lab standards.
Argh yes, the Bedford TK and the Thames Trader, the best selling trucks of the period.
If you look inside the scope calibrators they’re not particularly clever little boxes. Not sure why they fetch such a high price. You can calibrate a scope to a reasonable degree with a 10Mhz crystal oscillator and some divider ICs. Vertical cal can be done with a battery, pot and DMM. Rise time of a 100MHz scope is in the order of 3.5ns so you don’t need a crazy fast edge. I reckon you could build something superior for $5 of stuff from Tayda.
So, here's my first posting (hope I don't make any mistake).
My company is relocating and therefor filling the dumpsters with older TE that has accrued over several years and is defective or no longer in use.
Of course I'm not a TEA, but how could I just stand there and throw all this equipment out? So I asked and got permission to take what I want. Needless to say, in no time I had a huge pile of stuff.
Wow, what a nice haul you got. Where are you based in the world? I notice that you have a Phillip's 2521 and I've been looking for another as the one I have is in a sorry state due to in part broken plastic parts and sometimes needs multiple switch on and off cycles to get it into the self cal mode before it can used. Could I enquire if you'd part with it at all?

You are in serious danger of TEA; it is an easy slope down to damnation and degradation.
But never fear, we are here to help. But to be of most help, I need to know where in Germany you are located; the further north and west you are, the more help I can be.
P.S. you did make one mistake: not sending a PM to me a week before you announced this to the group.
In fact I have two of those. Yes, the plastics are kinda shitty on this one (well, not just on this one; although I have a sweet spot for Philips, they must have owned a plastics factory once: for a while, they produced more cracking plastics than electronics).
I'm from Germany, but that's of no consequence, as you're certainly joking - asking me if I'd part with test equipment ...
I must admit that these are not my first devices. When I learned that I might get these, I started looking for manuals and repair advice. That was when I discovered EEVblog and this very thread. I immediately knew I had to sign up.
Before this haul I already owned about a dozen DMMs, 8 oscilloscopes, some analog meters, a frequency counter, and components galore (I collect them as well).
I've never been a RF guy, but suddenly I start yearning for a SA. This thread is no good. Must stay away from it.
