Hi folks, i got both these drives and floppies don't work. Anybody know? how can get repaired. ? I am in Toronto, Canada. Thanks for any input. Regards - Bill Lauchlan

I only need the small opened part, not the rest. It simply unplugs from the rest of the module. Tom

I found a similar board which appears to be from a 83711. https://www.ebay.com/itm/284266773677 The small part that you opened seems to be the same. I guess your part number is

No hint in the manual. Tom

I would think it is a specialized microwave diode(s). Does the manual give any hints? Pete

Hi folks, here is the inside of the HP83732A A8A5 .01-1GHz power detector which is part of the SLPFA module: It appears to be passive, no power supply, top left RF in, top right RF out, pin to the

I have a couple of these, each had power supply failures.? Nice signal generators!? The power supplies were bought by HP thus no diagrams. They are somewhat standard switching supplies and have a

On the backside near the power plug there is an easy accessible fuse. Remove the power plug, slide the transparent plastic and pull out the fuse and check it. If it's not the fuse you need to remove

In case you haven't checked yet - there are quite a few Service Notes for the 5345A published on HPWiki (and in the files section of this group. Nothing specific I saw for A14/A15, but lots of

Had a power cut for several hours, after which my 8643A will not power-up. It has not been bothered by short power cuts in the past. Since it is such a weight-lifting exercise to remove it from the

This is what the board looks like. So, it must be those 50 Ohms tracks and stubs. Tom

Thanks, let me see if I can make sense of what's happening. I'll see if I get similar responses from my 8595Es. cheers, Michael

I would strongly suspect that it may be circuitry that is part of the circuit brd. such as a filter or other circuit. Some times they may indicate an encapsulated, micro circuit assy., or shielded

The problem is that the circuit descriptions and flowcharts are not very specific or complete. It's frustrating that it asks you to look at the timing circuits in A15 without telling you anything

That's what I suspected. I find it odd though, that such details are disclosed to the public. Tom

Harold beat me to it but here I go, anyway. The transmission line behavior of the copper traces is an active part of the circuit. The numbers are length and width in inches. Dave

With respect to the low power, I have confirmed that it is the Level Vernier Module (E5071-62283) that is kaput.? It should put out +3 dBm and is putting out -15 dBm instead, so 18 dB is missing

Which transistor (Q?) is the one that needs to be replaced. Also, what current must it deliver and what is the bulk voltage it works from? Mike Sent: Tuesday, February 11, 2025 12:27 PM To:
