Re: HP 8656B
Digikey has some in that range, but they are between $40 and $85. Hope this link works. Probably cheaper than a parts unit, and a parts unit may have the same bad parts.Maybe look on eBay but that is a crapshoot, but at that price.... On Thu, Aug 23, 2018 at 10:36 PM, Chuck <j-mcclurg@...> wrote:

HP 8656B
?
I have to thank you all for your advice on the Surge Suppressor for my
bench.? I will got through all the answers and see what will work best for
my Bench.
?
BUT....................
?
I was working on my 8656B tonight and found that I have about 1 VOLT of ac
on the +5V line!!!? This shows that C18 could be bad.? BUT? I had
to look it up in the Parts List as I was flabbergasted when I read the
value.............................13,000Mf at
40V....................................
?
I looked in the PL and, Yep, it says A10C19 is .013F at 40Volts!!!!! And of
course mine has to have been upgraded as it has a 24,000MF cap in it!!!!
?
Where/how am I going to come up with one of those I have no idea!
?
Hope someone can give me a clue as to what to do next, with out having to
buy another 8656B for "parts" and hope it will have a good C18!
?
Thanks,
?

hi,
Am asking for help from ?Hp / Agilent ?members ?to ?*deposit* ?{ i.e. UpLoad }, to an ?free & Open archive { perhaps, say: ko4BB Web Site, or other ? } : ? Any & All HP 70K Software ? ? ? ?related to the HP 70K MMS (hp 70000 series) systems & its individual modules, ROM's, & personality cards, calibration & analysis, etc.? It would be nice to start working on porting this hp 70K MMS software for use on a modern laptop with a USB-GPIB adapter, Hopefully it would be a group project, with all results posted to a Open & freely available Web Site. If individuals have any of this software, please attempt to upload it & Let us all know where ! ? ? >> ?so that we can attempt to move on this project !! thank you, rick **** |
Re: R¨¦f. : [HP-Agilent-Keysight-equipment] Need HP part ID 1826-0092
Yes, very interesting. Do you know what the specs are? There are opamps with way better specs than a 1458 these days. Offset voltage orders of magnitude less, outputs that are rail to rail. Sometimes though a product may be designed to assume not rail to rail, so that may not be OK. I never designed anything that could not take the rail voltages of the previous stage, even if the parts were not supposed to be rail to rail.

Re: HP 400 F/FL AC Voltmeter Service Manual wanted
As another? point of reference the serial number prefix is the date of the effective ENGINEERING CHANGE release date , NOT the year of manufacture.

Another thing about modern day "substitutes " is you? have to be aware that the "newer" devices because of the better high frequency response can have unexpected oscillations. No way to predict these but would not hurt to look at the circuit with a good HF scope after you install a substitute to be sure odd things are not going on

Hp 70909A, 70910A, etc.) Hi, i would be interested in all the HP calibration software - not only HP 70k, also for other HP test equipment. I think the easiest way to get the software running is an older PC where you can run the HP82324A Basic coprocessor, which is basically a HP9000/300 system. I'm currently trying another approach - emulating the HP9000/300 system on a modern PC. I've started to implement a HP9000/300 system using mame (), so it can be emulated. We currently support emulating the HP9895 and HP9122C floppy drive, and have HP BASIC running. What's missing to use that in a meaningful way for HP test equipment is the ability to talk via IEEE-488 to the outside world. There's some kind of MAME interface available called IEEE remotizer, which could be useful for talking to external devices. Here's a screenshot how HP basic looks in the emulator: In there are also other pictures of HP-UX booting in the emulator. the stuff required to boot HP-UX 9 is not upstream yet (SCSI controller, MMU stuff, etc). Currently i'm mostly alone working on the project, if anybody on this list feels like contributing/helping you're welcome to join.
