Down the rabbit hole again... of unobtainium tunnel diodes, that is. I couldn't get my "new" 3T77A to trigger at all. I'm actually not sure if the 3S2/3T77A/561A combo allows internal triggering or no

When I bought my 3S2 sampling plug-in, it came with a 012-0124-00 Sampling Head Extender (3 ft). Thought that was a nice bonus. Unfortunately some genius seems to have removed the push-on coax connect

Hello all, I have a 11301 that I would like to go through and adjust. It has some linearity issues in the vertical. All I have is the -01 test fixture and given the current ebay prices for the -10 and

I acquired an S-1 sampling head for cheap, "Untested, for parts only" (Yeah, right, since it came from a surplus test equipment company!). We all know what that means. Anyhow, as I expected, it doesn'
