HP 10544A Oscillator Service Manual Search

Hi Jim,

The Operator and Service Manual for the HP 10811 A and B is available at

Thanks for post this. Can you tell us which one is for the 10811?

Is there any index or cross-reference list to tell what the files are?

This seems to be a very unusual site. A woman author with a bunch of HP manuals. This is great, but any idea what gives?

The manual covers HP 10811A, 10811B, 10811-60101, 10811-60105 quartz crystal oscillators. It seems that all of them have the same circuitry, and that 10811B has a different case and connections. 10811A, 10811-60101 and 10811-60105 are closely similar but the specs are slightly different (phase noise not specified for 10811-60101, and the 10811-60105 being a 10811-60101 a bit less stable). Anyway, to quote the manual, 10811-60101 and

The file names are self explanatory: as an example, for the 10811 the file name is 10811-90002.pdf, where 90002 might be a date code. Look at the first groups of digits in the filenames.

Yes indeed. I didn't know that site until yesterday when I'we been pointed to it by the BAMA website (

Jim...email me and I may be able to give you a reference that will get you what you want.

Great - Thanks, Antonio.

I discovered the reason why I couldn't find the 10811 file using a search.

The "8" key has become intermittent on my keyboard and there are no files containing "1011":) Regards,

The -xxxxx (-90002 in this case) is not a data code. HP part numbers, for parts common to many instruments/products, are xxxx-xxxx -- and commonly known as "4 by 4" part numbers. Part numbers specific to a product or a small product family are "5 by 5" numbers, the first five digits being the product family number (such as 10811), and the last five follow a convention: those beginning with 9 are manuals and similar documentation. PC assemblies would have different 5 by 5 numbers. You'll find examples of these numbers in the 10811-90002 manual, both 4 by 4 and 5 by 5, and you can get an idea that the first

Thanks for the elucidation, Tom. Cheers, Antonio

Thanks to all... I actually have an original 10811 service manual. I was hoping to finding the 10544 service manual (if it even exists). I do have a copy of the schematic for the 10544, so I'm good there. Thanks again.. Jim
