HP 8563E Shows Signal Present at 100MHz and below without an Input
Hi all,
?
I have an HP 8563E which is showing signal present at close to 0dB at 100MHz and below without a Input connected. Above 100MHz the unit appears to be working as expected. Any thoughts on where to look? Thank you.

Re: Hp8660c repair, extender cards.needed.
IIRC, the kits for the different 8660 signal source models (A-D) are slightly different, with different HP part numbers.
Hello Olaf,
The repair/service kit for the HP 8660 series mainframe part HP's part number 08660-60070. I've attached a photo of one I found online (photo taken from .)
The repair/service kit for the HP 8660 modulation and RF plug-ins and frequency extension module (a YIG package required to support the 1.3 and 2.6 GHz RF plug-ins) was called the HP 11672A. A photo (taken from a defunct ebay listing) is attached.
The 11672A kit provides the two (heavy and rather proprietary) cables needed to bring the three modules (modulation, RF and frequency extension) out for repair/testing. The HP 08660-60070 board kit is extender boards needed to bring the (numerous) plug-in PC boards in the mainframe up for repair/testing.
The connectors on the two large cables in the 11672A kit I believe were made by Winchester and include a number of coaxial cable contacts.
Good luck in your HP 8660C repair - they are nice machines, although I've found that their CW (but not modulation) capabilities can be somewhat duplicated by a TinySA Ultra and a small number of SMA attenuators.

There are these perennial concerns about them cold shouldering people using legacy hardware. I remember the last time this went around they did a whole charm offensive online. On Sun, Feb 16, 2025 at 12:23?AM Peter Gottlieb via groups.io <hpnpilot@...> wrote:

Hello - Does anyone on this group use the Keysight Forum at ?
I have had poor luck with it for the last few years.
I have had no responses to inquiries about still in product test equipment. Prior to that, Keysight personal actually helped but no longer.
Inquiries to the Keysight tech support contact webpage always results in "We're sorry, you don't have a contract so we don't want to help you". Even for basic and simple questions about features and so on.

Re: Hp8660c repair, extender cards.needed.
If I could borrow such a setup I would repair and calibrate my 8660C and multiple plugins. I’d like to do that before selling/trading the setup as I now use a 8643A. The cool thing with the 8660C is with the right plugin it will go much lower in frequency than the 8643A. So maybe I need to keep it..

Thanks for the update.
I think I found a picture showing the 10811A in a unit also.

Re: Test Set Program Development Tool DEV_PL on 3.5" floppy
IMSAI 8080 I remember from 7th grade in 1977 and 1978.? I was in junior high in Palo Alto, California, and we had one in the computer lab.? Also had a DECWriter, a teletype, and an Anderson Jacobson acoustic modem that would connect to one of the mainframes or minicomputers at Stanford University at the blazing speed of 300 baud!? I've heard of the other vintage items you have lying around, Roy, but never used them.? Nice collection you have, Roy!

Re: 5345A electronic counter *restoration adventure*
I have digitized the first fiche in the set (that has the contents table etc. ) and the schematic for A15
They should be in the instruments by part number directories in the files sections in a minute or so
?
Take a look at the ,pdfs and let me know if there are any other sections that you want digitized

Re: HP 8670B amplifier - does it ring a bell with anyone?
I can't find anything in my docs.? In the 1985 index of fiched documents (files section) there is no entry for 8670A or B
?
May indicate that?
- no manual was ever released
- by 1985 it was no longer supported even for service
- part of larger equipment and documented in a system manual
?
To check for (2), I'll take a look at an earlier fiche index and see if it is there

Re: 5345A electronic counter *restoration adventure*
I have fiche? -90021 dated September 1975 as being for serials starting 1528A
This does not seem to chime with your earliest version but the may be because my dates are fiche release dates and the underlying paper manual may be dated differently
?
I also have something marked Electronic Counters and Plugins Users Handbook (Sept 1974 and March 1986 rev 1) 05345-90015 that may contain additional circuit operation details
Also option 011 Operating note? 05345-90011
And GPIB interface supplement? 05345-90022
?
- If you send me a link to your 90025 manual then I will compare to my earlier one to see if there are any differences
- I will take a look at the handbook and see if there is anything helpful there

Re: HP 8670B amplifier - does it ring a bell with anyone?
Of course, the first two digits of the serial number would help fixing this in a period of time. But if there are no pictures, we are 1000 words short of a haiku.
?
I do like the idea of a System component.

Re: 5345A electronic counter *restoration adventure*
OCXO part number is 10554A, and it is installed next to A8 PLL board and PSU boards.
Actually looks that it is the only functional module on my unit, after about 30 minutes of warming up, signal is very good and stable.
