HP-8562A repair

Jose V. Gavila
Hi Joe,
I have started this new thread, but with the previous comments attached: Perhaps we should start a 'new' thread but mine, on power on, gives ERRMaybe... now I feel the urge to fix my unit :-)!!! Well, let me look at the notes I took and also to the pictures (big hint: take lots of pictures of all you do, they are very valuable later!) and I will get back with the faults I found on my unit. Best regards and thanks for igniting the fire again :-) JOSE -----Original Message----- Hi Joe, I have an 8562A project as well that I haven't had time for yet.Interesting ! Mine was bought at eBay UK cheap, as it was non working. When I got it and fixed the power supply, I was able to barely see (without light in the room!) that it had more than 43.000 hours on it. It generated several errors: ERR 304 ROL UNLK, ERR 324 FREQ ACC and ERR 301 YTO UNLK. I was able to fix all of them (I will detail that on another post) and it seems to work, but then there is the extremely dimm display. And that is the condition it is now.

I also have a HP8562A (sn: 3040A5503, quite low milage btw) to work on. The sa fires up and runs the startup procedure without any errors. However the amplitude calibration at the higher end seems to be low by 10-15 dB. I do not suspect the mixer, right now. The cal signal at 300 MHz is fine. I got myself a TAM (HP 85629A, rev: 870218A). Page 3-6 of the sa Installation manual gives a table of compatibilty between the two. Unfortunately my numbers are not stated. Can someone with a newer manual give me the correct table, please? In addition: when I start running the Automatic Fault Isolation routine it aborts at test 3: IF log check fauilure. "Cal Oscillator tune line error" and some more info. But before digging further I'd like to know compatibility between TAM and SA. It could be the reason. Can the TAM be upgraded if necessary? Thanks a lot so far, I expect more to come. Kind regards, Harke --- On Thu, 1/3/13, Jose V. Gavila <eb5agv@...> wrote:

Do you have Firmware Note, Agilent Technologies 8560 Series, 85620A, and 85629B, Part Number 08560-90163? It outlines all the 'requirements' for using the TAM with the various firmware choices for the SA. It is a .PDF file that I got off the Agilent website some time in the past. I recall it was very difficult to find. I just went to the Agilent website and could not find it. If you don't have it, I can send it to you via PM. I think you will need a 85629B. but I am very new to this area. Another resource is the Agilent Forum's. I posted a question about my issue about a year ago and got a very knowledgeable response in a couple of weeks. Although the 8562A is no longer supported, there are some folks there that appear to be able to help a lot. I have been reluctant to open this particular instrument due to concerns about my 'skills' at this level. However, I'm gaining confidence and getting closer to the required 'courage' to open it up. Good luck. Joe -----Original Message-----

Hi Joe,
... I have been reluctant to open this particular instrument due toDon't worry about that!. If I have been able to (almost, except CRT) fix mine, everyone could do it :-)! It is a matter of apllying logic and use the available tools. I don't have a TAM and you can do also without it. In fact, I think you learn more if you don't have it :-). And, for me at least, it is a matter of learning new things. Then, if the result (i.e. the fixed equipment) is useful for my work, still better! I plan to develop a WEB page on my site for the 8562A repair. I have been re-checking my notes and pictures and I think it may help some others with similar troubles. I will keep you posted when I upload it. Regards, JOSE -- 73 EB5AGV - JOSE V. GAVILA - IM99sm La Canyada - Valencia(SPAIN) AGVradio Personal WEB |
