Manuals, Service Notes, Brochures, and Data Sheets

The historic rollout of Hewlett-Packard equipment is detailed below, along with our archive of equipment manuals, service notes, data sheets, brochures, and any available collector references. The dates below mark the first and last year of appearance for an item in printed catalogs, or price lists. Models prefixed by an “*” character use waveguide or band designations (i.e. “*281A” waveguide launch is/was available in S281A, G281A, through P281A), and “#” represents suffixes (often for dB attenuation or coupling).

Please click here for our PARTS PAGE. Also, collectors interested in the age of vintage equipment, please see the SERIAL NUMBER page.

Sorry, but the dates column are current only through the 1955 catalog… Please volunteer to give us a hand! There are other versions of this kind of table published, but all lack the date ranges critical to collectors. There are some old HP manuals available at BAMA and their mirror site, as well as not-so-vintage manuals from Agilent in their Technical Support section, or at the Agilent FTP account that holds manuals not yet posted …
