Re: [time-nuts] Control and monitor program for Spectracom 8195B
Thank you, thank you, thank you, thank you, thank you. Now I can unify GPSDO monitoring into just one program. I'm also using LH with TICC. The fact that LH recognizes trailing channel ID string resolves an issue I was having. I still don't know why I could not received the executable. My only guess is, somewhere along the chain, automated system recognizes the EXE format and alters it. Would you be posting the new version in the LH thread on EEVforum? It's getting late in Florida, so I'll try to see where it is tomorrow.

Re: [time-nuts] 5370B input board
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.

Re: [time-nuts] 5370B input board
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 ….)

Re: [time-nuts] FSA3011 Frequency Stability Analyzer
Hi There are a lot of “stock” programs out there that will handle this sort of “wrap” process. The obvious gotcah is porting them to accept the output of the device.

So that's a "no" I'm guessing. :-( Jim On Sun, 21 Jul 2019 at 17:38, Jim Palfreyman wrote: > Hi All, > > Has there been any advances on the failing chips (5088-7061/5088-7062) on > the 5370B? > > Jim > > ___ time-nuts mailing list -- time-nuts@lists.febo.com To unsubscribe, go to http://lists.febo.com/mailman/listinfo/time-nuts_lists.febo.com and follow the instructions there.

Wha's the problem? If it's just running out of high order bits in a counting register, I can fix that with a post-collecting pass. You could hack the collecting software to do it. In one sense, it's nice to keep the collecting software clean and simple and log exactly what goes in to it, but if you collect enough data, then the extra pass gets annoying enough that I would take the time to fix the collection step and double check things so I'm pretty sure it won't turn into a source of problems. -- These are my opinions.
