My 3580A spectrum analyzer works great but is much in need of a set of knobs. All the large ones with labeled "skirts" are either broken or missing entirely/replaced with nonlabeled knobs. Any leads appreciated. thanks Charles

Anyone have an emailable copy of the HP 428A? Sam W3OHM

Does anyone have an e-mailable manual (or at least a schematic) for an HP 204B Oscillator. It would be sincerely appreciated. Tom Leedy Clarksburg, MD

My usual plea.......anybody have a list of 3586c commands? (I never get manuals with my stuff)... Thanks to all who replied regarding the peeling meters and all.. 73 Tom

Gentlemen: You might try an MTA-156 IDC receptacle used for wire-to-board interconnection. They are available for about $1.00 each. The 12 position unit (you must trim off the extra "hole" with a Dremmel tool) is available from Newark Electronics as 15F1426. Regards . . . Tom Leedy

I have a 1631D with all the Pods, but missing grabbers... And finding affordable kits has been impossible... Is it possible to make grabbers myself? I thought the Pods have MTA 156 connectors.. And maybe I can make them.. Thanks, Maurice

I am interested in manufacturing replacement A/D boards for the HP 54111D. I saw comments on the unavailability of schematics. Does anyone have further info on contacting Agilent or reverse engineering these boards (54111-66501)?

Hi All I have obtained some software for the 4952A protocol Analyser. These have been copied using the LIFUTIL utility. However wheras the data files work fine the applications (things like a VT100 emulator) give an error "Application Denied". I suspect and have read somthing about this being some HP copy protection. Can anyone help or make any suggestions? Many Thanks Richard

HI guys I have a HP 8558b with a hp182t m/f I have two problems one is the display on the 182t shows a sharp dip in the middle of the screen wether the 8558b is plugin or not . the second is the 8558b plug in .I have the service manual for it and the plugin doesnt work .I have found that the sweep generator is not the same board as is detailed in the manual and it has 08558-60018 on it can anyone advise me if this board is a updated board and where i can find information on it Thank you ian wells ianwells@...

Does anyone have any CPU Board data. I have the service manual such as it is. I'm having a problem with the analog bus voltages coming up as out of range when I measure them within range. Thanks Richard Murray

Would anyone know where I can obtain the rotary switches on the front panel of a HP8558B plugin? thanks ian

Ian, In the HP 8558B service manual, it looks like those switches are just assemblies of many different HP part numbers. I could be wrong. I've never looked at an 8558B. But I didn't notice a part number for an entire rotary switch assembly, except "Front Switch Assembly (Mechanical Parts)", HP part number 08558-60100, which includes all of the mechanical parts for the entire front panel switch(es) assembly. Your BEST bet is probably to find an 8558B "parts unit" to get the parts from. You can probably find one on http://www.ebay.com, eventually. Note that you can put an "auto-search" on eBay, so you'd be automatically emailed whenever anything matching your search came up for auction. Just go to "My Ebay", then "Favorites". Darn! I just searched ebay, for "8558B", and then clicked on "Show Completed items", and it looks like an 8558B Front Panel Switch Assembly sold on Dec 15th, for $57.55. Maybe you could contact the buyer and see if you can get some parts from it, or maybe just get all the rest of it after he gets what he needs. You can go to http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2580863244&category=25414 and then click on the winning bidder's ID (kcands). You could also contact the seller, similarly, to see if they might have more of them, or the parts you need. (They are a test equipment dealer in Wyoming.) Also, you could try asking Walter, at Sphere Research, at: http://www.sphere.bc.ca But, if you do need any HP part numbers for individual switch parts, such as rotor/contact assemblies, shafts, or whatever, I can look them up for you. You would need to be very specific about the locations of the parts, since the rotary switches' parts are not all interchangable. I also have the full service manual available (362 pages in two manuals), on CD, at: http://www.fullnet.com/u/tomg/manuals.htm Good luck!

I've recently tried to use a pair of old 37203A HP-IB Extenders to extend the distance of several IEEE-488 instruments from the controller. I don't have a manual on hand, but I thought the units should be fairly straightforward to use. I set the "controller end" as Master and the "instrument end" of the link as "Slave," the rates at the same setting (Normal), and connected the power and -488 instruments. Although I can see a series of negative-going pulses on the coaxial interconnecting cable, I can't seem to get communications between the controller and the instruments. The length of the cable is about 150 meters. Can anyone give me any guidance for their operation? There are a few "mystery switches" inside the units along with a jumper printed wiring board -- I left all these as they were. Any help would be sincerely appreciated. Regards -- Tom Leedy

hi guys i am trying to locate a hp part or compatable part out of a hp8558b it is a hp part number 5062-2805 or sugest a online cross reference guide i can check out Thank you , Ian Wells, Kerinvale Comaudio, Biloela,4715.Qld. www.kerinvalecomaudio.com.au email- ianwells@...

Mixed Signal Tester experience IMS is preferred, but experience with catalyst, S9K, HP93K, Agilent etc will get the considered by the manager. 3. Analog test experience 4. A solid understanding of BOTH analog and mixed signal concepts including measurement methods. Good communication skills are a must. Unix ADDITIONAL SKILLS DESIRED: Perl, Verilog, Spectre PRESCREEN QUESTIONS TO ASK: 1. What is your mixed signal test experience? (Describe a few sentences) 2. What was your tester experience? What tester and what did you do with it? (maintain the tester? Program the tester? Push the buttons on the tester?)

Walter, I looked up your HP part number, 1884-0019, in my copy of the FedLog (Federal Logistics) database. This is one of the first times it hasn't shown ANY equivalent part numbers and other manufacturers. But it did have some technical descriptive data, which I'll paste below, in case it might be helpful. Good luck!

Hi All, Looks like it's "request a service manual" time. The mil site had nothing. So, I request it. thanks.

Just bought an HP-184A scope today at the monthly Livermore Electronics Flea Market. Plus, a Tektronix 7704A mainframe scope....$ 15.00 !Checked it at home.The readout does work.In decent,good condition.A keeper. Used my 7000 series plug-ins. OOOPs ! Am I allowed to say "Tektronix"? Has 2 plug-ins; a 1809 4 channel, 100 MHZ vertical. And an 1825A timebase and H amp.The mainframe is a storage type. Couldn't pass it up for $ 20.00. Now, for the interesting part:No trace, but a glowing screen. Beamfinder is useless.No spot. Just the screen glowing. Tried BAMA for the service manual.Not in there. Next, will try the mil site. Stand by for a service manual request. Just to let you all know what can be had, at the right price(s).
