Re: Synthesizer module in ESG series E4435B
Thanks to everybody for great discussion.? Despite initial diversion I have found that U313 Agilent 1GC1-4210 has struck yet again.? It had weird failure mode where it would change its division

Re: Size of hex (?) screw in knobs of 5370B time-interval counter
No way - I will lose them before I die. Or at least I hope that's the case, since otherwise I would have a pretty short lifetime! I had a feeling they might be 0.05", as they looked the same as the

Re: HP 8922
If anyone here wants to try, I have a few spare E5515Cs here. I bought them opportunistically; I have two in my lab which I use for actual cellular equipment development. (*gasp!*) I will not

Size of hex (?) screw in knobs of 5370B time-interval counter
I have a few HP 5370B time-interval counters of various states of cosmetic and electrical condition. I wish to swap some knobs between the instruments, as some are in better condition than others. Can

Re: HP 8922
Adapting a 8922 for amateur (analogue) use would be more about re-writing the software than changing the hardware. Another issue is that while the signal path is fairly wideband the calibration data

Re: Any ECAP historians out there?
PM sent. Haven't figured out any way to confirm that in the groups.io interface; PEBKAC perhaps :-<.

Re: What were your easiest and your most difficult equipment repairs?
Rather than easiest or hardest, how about luckiest? I was given a 50" plasma tv once where the top half of the display was dead and the bottom half worked fine. Once I got inside I could see that the

Yet another TG project
I have a number of tracking generator projects in the works, over years, for the 8566 SAs. When I acquired a couple almost-working 8568s a few years back, I figured I'd make one for them too, if I got

Re: Any ECAP historians out there?
I think it would work more than fine as a little bit of JavaScript running in the browser on mostly anything. After all, the era of intelligent terminals is back with vengeance. You can program them

Re: Any ECAP historians out there?
Great stuff. I have a copy of that book, and am looking for the actual software.

Re: Any ECAP historians out there?
Hello, Tom-- I encountered ECAP via an university's IBM 1620, which offered 24- to 36-hour turnaround. That made for slow debugging. Maybe someone with time on their hands could recode ECAP for a

Re: HP8568A strange problems
I've got the 8568 "working" now with a different IF/display unit, and it's pretty much the same behavior - OK when nice and cold, then the sweep stopping and other problems if it's warmer. I'm taking

Re: HP 8922
From what I see the differences in models is mostly in the power handling of the front end. There are other cell phone features between model variants, but, those do not concern me too much. I am

Re: HP E3614A Power supply Annoying
Based on images I'm finding online, they appear to be Phoenix Contact Combicon FFKDS or FFKDSA terminals.? I don't think you'll find a mating connector for direct connection as they're intended to

HP E3614A Power supply Annoying
OK I have an HP E3614A 8V 6A? power supply for testing some portable radios. I use the remote sense because the application requires it. This requires using the plug in terminal strip on the rear

Re: Any ECAP historians out there?
Hi Brad, I don't have any need for the book but did use the ECAP program on an IBM 1127 system back in the late 60's. The element nodes were entered on punch cards and a printout of results came

Re: HP 8922
I bought my 8922M for $197, with options 001 and 006. That's the OCXO and SA options. It looks like the CRTs from 5" monochrome security monitors will fit these units, if needed. I have a tri-pack of
