Re: paper manual wanted (and CRT bezel)
Frank,

There is a company here that sells manuals, www.manualsplus.com . The 182T is going for about $USD 30. I have one (00182-90909) but I'd rather not part with it. My manual has changes up to 2010A-xxxx; I don't think there is a separate manual for the later serial numbers, just change sheets. If you can't get a manual with the changes for your serial range, I'd be willing to copy them and send them to you for postage only, or .pdf. It's about 15 pages.

Re: Power sensor calibration system
Ruben,

You didn't mention which sensors and meters you are using: thermistor (432A/487A type) or thermocouple (8481A type). Not that I know the answer in either case, but there's a fairly large difference. I clean SMA and N connectors using a Q-tip soaked in isopropanol, though ethanol would work fine also. SMAs especially are sensitive to debris on the insulator. Frequency measurement accuracy is a complicated question. The accuracy of the 8560 series is given in the calibration manual as: f*DFR_rel + 2N (Hz) + 1LSD where f is the frequency, DFR_rel is the relative accuracy of the reference, N is the harmonic mixing number (depends on f) and 1 LSD is the least significant digit of the reading. DFR_rel depends on option. If you use the GPS as a reference, it's probably around 10^-11, otherwise probably around 10^-7 up to 10^-5. The mixing number is given in the spec sheet as: 30 Hz to 6.46 GHz: N =1 5.86 GHz to 13.2 GHz: N = 2 12.4 GHz 31.15 GHz: N = 4 31.0 GHz to 50 GHz: N = 8 Basically, the first term is the error from the reference, the second is the integrated phase noise error of the instrument and the 1LSD is the usual least significant digit bobble. Here is the spec sheet: Erich --- In hp_agilent_equipment@..., "ruben_rock" <ruben_rock@...> wrote:

Hello Benoit,

Anyway now I know where to find a 180 replacement CRT :-) In this moment I'd be more happy to find a 182C CRT replacement, but I'm not sure the expense would be worth it. Anyway, I still have to make some more tests on the 182C before concluding that the CRT is definitely bad. At this point I have more mainframes than plugins :-) Thanks and best regards Francesco |

Re: Noritake displays (2090-0293) ???
Alexander Whiplash
Great tip, Stan?!
I pulled out the module and found it to be a GU256X64-315. This is used in: 81101A 81104A 8110A 81110A 81130A 8114A 8169A E5574A Noritake has some GU256x64 modules but not this one. Their smallest 256x64 unit has an actual display size that is 115mm wide which is the same as the window opening in the front panel, and the PCB behind the glass is smaller. It looks like it is too late to go the distributor route. Perhaps even Agilent is building some of these products from?a fixed,?limited inventory. AW ?

Re: 8640A attenuator- plastic cams fell apart
Hi Dave,

Show quoted text
Quickly I can think of three options plus the one you already mentioned. Certainly, if you can carefully glue them back together they would make reasonable mold master for silicone molds and castable Urethane. If you're handy with a CAD program you could reverse engineer the cams and have a machine shop - hopefully a good buddy - create them on a CNC. Alternately, I believe some of the newer polymers used in Stereo-photolithography are amazingly strong. The same CAD data could be used to "grow" them that way. It might be possible to tree all the cams so you could get them done for a single charge. Of course, looking for a parts unit is an option but the cams are likely to be at or near the same condition. I used the silicone to make molds and then cast Urethane parts and that works very nicely, but it certainly takes times. Just some thoughts. Regards, ken ----- Original Message -----

Re: Noritake displays (2090-0293) ???
The one time I had to fix an 8110A with a dim display, I ended up getting
the Noritake part number from the label on the display module itself and ordered a replacement direct from a Noritake distributor. I don't remember the exact cost, but it was a lot cheaper than having Agilent repair the instrument, and, as I recall, it was an easy fix. Stan From: hp_agilent_equipment@...

The part is used in some currently orderable, currently supported products like the 81110A. However, the part is not available for sale.

While not an exact match, I have a paper manual for an HP-180T/TR unit. It is essentially the same as the HP-180A except for the rack-mount form factor. Let me know if this might be of help to you (copies or other information). I also have a few boards and a CRT from a 180T/TR donor unit but no CRT bezel.

Re: HP 8565E problem

the 8565E specifically, but they'll help. Their schematics volume does cover all models in the series, and it's almost certainly the latest edition since it came directly from Agilent last year. I don't see the 340 or 338 errors in the 8560E manual, but 319 is listed as "The YTO coarse tune DAC is near its limits" and 351 means "YTO error voltage is not settling." Sounds like there's a problem in the YTO main-coil driver section. If you can find an 85629B TAM module, the YTO adjustment procedure will likely reveal or even correct the problem... otherwise you can try the non-TAM-based procedure in the 8560E manual, noting that it might not apply to the 8565E or might actually make things worse. -- john, KE5FX -----Original Message----- |

HP 8565E problem
Hello group,
After year of a good service our HP 8565E is getting some illness. I have tried to look to 8560x service manual which was available, but the error numbers, which the 8565E gives are not there. I am getting following error: ERR 340 SAMP AGC ERR 338 LOMA AGC ERR 319 WARN COA ERR 351 setrl some of the texts could be wrong read, the errors display one over each other and they are not easily readable. The frequency display seems to be unstable, jumping erratically in the range of 100Mhz around the correct frequency. The errors are seen just after switch up, when displaying full sweep, and after some time it is when greater span is used (above 100MHz), below that span it seems to be stable. I suppose it is something with YIG or frequency synth.... I will appreciate, if somebody could interpret those errors for me, or even better, if somebody knows a reliable source, where the service manual could be bought or downloaded. I have looked to Artekmedia, but I have not found it there. Thanks for reading and will be gratefull for any info, OK1VAW, Vojtech, Prague. |

Re: HP8568B Error Correction Routine failure
STEVE REEVES
I've worked on a lot of these in the past 25 years and have found the step attenuator to be one of the weak areas, especially since it's an electro-mechanical part. The internal O-rings age and get gummy and stick. The contacts that turn off solenoid current get intermittent. And a strange thing that I have found is the U-channel that encloses the solenoid will develop a magnetic attraction mostly on the bottom end that can stick the section. An easy fix for this is to loosen the 2 hex-head screws and carefully slide the U-shaped piece out sideways. Then affix a piece of transparent tape to the inside bottom of this piece and trim the tape edges flush.? This is also a good time to check and clean the solenoid contacts (not the attenuator contacts).
Re-assemble and test. Steve ________________________________ From: John Miles <jmiles@...> To: hp_agilent_equipment@...

Sure, but since he sees exactly the same signal level with both 40 and 40+20 switched in, I'm not inclined to think the 20 dB section is switching at all, open ground or not. It seems that it would have to be making a straight-through connection for those two settings to match, wouldn't it? Be interesting to hear what turns out to be wrong with this one. -- john, KE5FX [Non-text portions of this message have been removed] |

paper manual wanted (and CRT bezel)
Hello all,
I'm looking for the following (paper) service manuals, any offer is welcome (even if not exactly matching my serial numbers): HP-182T ser. 2010A-xxxxx HP-180A/AR ser. 816-03899 Y59-180AR (old serial scheme?) HP-1821A ser. 809-03023 Y59-1821A (old serial scheme?) I'm also looking for a replacement CRT bezel (just the frame in front of the CRT with the 4 screws holding it and maybe the screen filter) for the 180AR (should be the same of the 180A), should anyone have a dumped unit for parts. Thanks in advance and best regards. Frank IZ8DWF |
