I need the wiring for the plug on the back of this unit. thanks doug

I have a 5300A measuring system readout with a 5302A 50 Mhz counter. When I first turn the unit on, with the function knob dialed to "check" the counter reads 10.0000 Mhz but after it warms up for a few minutes, the counter begins to read 9.9999999 MHz. If I plug a cable from the front bnc to the timebase output it reads 10.0000 Mhz. I have adjusted the crystal frequency to give correct readings from a more accurate 10 Mhz reference. Is the check function supposed to read 9.999999 or is it supposed to read 10.0000000? I don't have a manual, so I don't know. Thanks, Steve Hogan

Dear Colleagues, I'm looking for a HP 5355A plug in (frequency converter) for use in an HP 5345A counter. Anyone who has a spare kindly email me at: cesium_mike@... Regards, Mike, W4XN

Anyone know of any Tektronics forums? thanks Doug

I sorry to get off topic but I have tried many forums looking for a schematic for a Eurotherm 832 power supply. Eurotherm list this with a 831 on their web site, but the 832 is different.Eurotherm Europe states this was a USA only model. Eurotherm USA wont release a copy. I thought maybe Eurotherm may have not made this and have done searches on other supplies to find one similar but no luck. thanks. Doug

Does anyone have an operator's manual (or O/S manual) for the HP 6177C current source that they can lend me?

Synthesizer lock on all frequencies but has about a 10 KHz FM signal on most frequencies. Using a scope on the output pins of the Phase detector chip shows the expected pulses but about a ten KHz amplitude modulation on the pins. Powwersupply looks clean. Chip jhas been replaced. Anyone seen this before? 73 Tom WB3AKD

Can anyone point me to a pdf or something on line with HPIB command list for the 8753? r Tom WB3AKD

I am looking for a hp7475a service manual or schematic. I am working on a project that includes this plotter with modifications. Any help would be appreciated. Rick Paul

Hello. My name is Robert. I am in search of some of the older Hewlett Packard Military (tube type) oscilloscopes. I am currently in search of these (two) particular models and the manuals at this time; OS-121B/USM-140 AN/USM-140C I am also looking for a few other Military Hewlett Packard tube type oscilloscopes and manuals as well. I am willing to purchase them and pay for the shipping costs too. Is there any one of you folks who might have either one of these units for sale and or perhaps you could put me in touch with a person(s) and or a company who might have one or perhaps a few of them in (excess) stock? Enclosed is my e-mail address and home phone telephone number for someone and or a company to reach me at. e-mail address; romhifi@... Home#; 360-459-1874 Also, I am also open to swap/trades for these types of equipment and for those who are interested you are welcome to contact me. Thank you for your time and have a nice day. Respectfully, Robert

Looking for some info on a broken cap..........Manual says it is a selected part, with the ave value given as 5pf mica 10% 500vdcw (from Hi Q div of Aerovox Corp Olean NY)Hp part no. is 0150-008. This little pesky varmint looks just like a small resistor (1/8 dia,x 1/8 long)The colors are Blue/gray/white/gold, from what I can figure from all the old cap charts it should be 68pf or 6.8pf. Before it broke it measured I think around 9pf ( with it connected across double bannana jacks)Any clues on its replacement? Since this is in parallel with the scopes or meters input capacitance, its effect would seems to be neglegible. Survey says.............. Dave

--------------------------- Tom, I've never seen one do that. But I've only had a few of them go through here (bought surplus and resold). My obvious suggestion would be to buy a parts unit and take the meter out of it. They are pretty inexpensive, nowadays. I'll check to see if I have any left. If so, I'll list them at http://www.fullnet.com/u/tomg/hp.htm (or you can drop me an email). If you want to go that route, you should also check www.ebay.com . You can also 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" and then "Favorites". And, just in case one of their good warehouse sites is near you, you should also check out http://www.govliquidation.com , since all you want is a parts unit. Good luck.

Anybody have a solution for the peeling meter faces commin on HP meters like the 400EL? 73 Tom Dawson WB3AKD wb3akd@...

Hi all, Most of the manuals are for relatively new equiment. Please realize the newer manuals, in 3-ring binders are heavy, so shipping can sometimes cost more than you'd expect. Prices shown below include USPS Book Rate in the US. That service can take 8-10 days, but quite a bit less expensive than the alternatives. Microwave Power Meter: These manuals are for the new EPM series. EPM-441A/B is also known as E4418A/B, and EPM-442A/B is also known as E4419A/B. * User's Guide for EPM-441B (E4418B) * User's Guide for EPM-442A (E4419A) still shrink-wrapped * Programming Guide that covers both 441A and 442A $15 for all three, including Book Rate for 9 pounds in the US. Power Sensor - 8484A * Operating and Service Manual. Pretty small, $2 will deliver this one anywhere in the US. Microwave Sweepers - the outstanding 8360 series, including the 83620, 83630, 83640, 83650 and variations, including B and L models. * Troubleshooting Guide, still in the shrink wrap * Service Guide (not in shrink wrap but in like-new condition) The two together constitutes the instruments' entire service documentation $15 for the set, including Book Rate for 11 pounds in the US. * Also have a second troubleshooting guide for the sweepers, but not a matching service guide. $9 including Book Rate for 7 pounds in the US. Spectrum Analyzer - the 8560E high performance series. These manuals cover ALL the analyzers in that product line: * Mass Memory Module (that's the card reader on the back panel - has its own manual and it's needed to do programming, downloading, etc), Installation. Operating, Programming and Service Guide * User's Guide - this thing is HUGE and covers all the functions. * Calibration Guide - bigger even than the user's guide. Don't think you can calibrate the instrument with just a scope - this guide includes long lists of equipment and software required to do the cal, besides the procedures themselves. $18 includes Book Rate for 20 pounds in the US for all three. Function Generator - 3312A * Operating and Service Manual This one's light, so shipping isn't so bad. $4 delivers it Book Rate in the US. Power Splitter - 11667A * Manual has some writing on the front. Low page count, this one is $2 delivered in the US. Multiprogrammer 6940A/6941A, Relay Output/readback Card, model 69433A * I don't even know what the thing is, but if you have one and need the manual, here it is. $2 delivered in the US. Actually, I think it's some sort of automatic data collection system. Power Supplies: E3620A. This is a recent power supply. This manual is surprisingly complete, with full schematics. There's enough info here that you could replicate this benchtop low noise power supply. This is the operating and service manual. $5 delivers it in the US. HP=IB conntrolled "system" power supplies: * This is just the operating and programming manual, no service info. Models 6632A, 6633A, 6634A. $5 delivered in the US. I've been selling similar manuals on eBay for a few years, most of them came from buddies who left the employment of HP / Agilent and had me helping them unload remnants from their garages. These are the last bits I have sitting around and I just want them gone. First come, first serve, but am willing to entertain offers on the lot. 73, Dave W8NF __________________________________ Do you Yahoo!? Protect your identity with Yahoo!

I didn't expect to get such an overwhelming response!

Hi, Can anyone help with a copy of the 5062-2119 Data communications test library that shipped with the HP4951C & HP4952A Protocol Analyzers? Am also looking for the service manual for the same equipment. Many Thanks Richard

Good Morning Gentlemen, I have sent in a few new HP scans to BAMA. Good on ya BAMA! -Richard VK5ZLR

Hello all, I'm looking for an Hewlett Packard component, for my HP3336B generator. It is marked as "1SB1 0021". Could you please help me to find this component? Thanks for your courtesy Best regards Marcello Pellerano - ITALY

Hello All, I am in need of the power supply and oscillator schematics for an HP 651B I am repairing. I have a service manual but it is for an older model than mine. My unit has a serial number of 811-03132. Can anyone help me out with a scan of the 2 foldout pages for this oscillator? I would really appreciate it. It is not significantly different from the older unit, but it appears that Si transistors replace the Ge units seen in the manual I have. To make matters worse, someone has been in there and made some changes/repairs that appear to be less than professional! Not sure anymore what are original parts and which have been changed! The parts pages which describe thea transistors and diodes used would also be helpful. Any help would be appreciated. Thanks, Mitch

Greetings - After searching the excellent lists from tbfowler, came up dry. Looking for service lit/schematics (have the operating manual) for this HP54720D scope 4G amp plug-in designated HP54721. The cal output on the plug-in is not working, i can visually trace but, much better to have schematics, board is multi-layer and I don't have extenders. Thanks!
