Hi All, Has there been any advances on the failing chips (5088-7061/5088-7062) on the 5370B? Jim

So that's a "no" I'm guessing. :-( Jim On Sun, 21 Jul 2019 at 17:38, Jim Palfreyman <jim77742@gmail.com> wrote: > Hi All, > > Has there been any advances on the failing chips (5088-7061/5088-7062) on > the 5370B? > > Jim > >

Jim Not aware of any work. I did a hack as I recall on one unit. That was a ecl inverter biased linearly etc. Serious hack. (Some would say ugly) But if its dead, its dead nothing to loose. That chip is actually pretty complicated. As I recall the threshold setting is handled in the chip. Can more modern chips work and give threshold I totally believe that. Regards Paul.

Hi Pretty much the same “no” as on the input circuits on the 5335 …. ( best to avoid +5V on a 5335 input with the attenuator set to 1X ….)
