Re: 2445A calibration
After seeing a tip here on a 2465 for sale for $50 plus shipping, I bought it. It was advertised as having a bad horizontal switch - it had been dropped on it. Well they were right, it was bad. I was able to get a replacement panel for it complete with all the controls for $37 IIRC. Now it works great. A few years back I bought a 2445B on which everything worked except the parametric functions. I thought it would be good to buy another 2445B for parts. When it came, everything on it worked except Channel 1 which was very noisy - turned out to have a fried attentuator.toggle quoted messageShow quoted text
At this point, I decided it might be good to have one of them calibrated. I sent the one needing a new attenuator to one of our members who does this sort of thing, and had the PS recapped, the A-5 Board smt caps replaced and the NVRAM replaced with a socket and a FRAM. It came back really nice with a great trace and everything working. I now have a certain to be good 2445b, a 2445b which can be used manually and seems pretty good, and the 2465 which also seems ok.
This is nuts.
I need to get rid of at least one of these, but can't bring myself to part with them.
