  • Notes:
    • I have one and I find it to be a nice scope, although I suspect the Rigol is just as good (for a fraction of the price).
    • It appears to be a re-badged Rigol scope. http://mightyohm.com/blog/2009/11/agilent-dso1000-firmware-update-confirms-rigol-connection/

It can be really frustrating to try to fix a piece of expensive test equipment without a manual. There are lots of sources for service manuals, both free and not-free. Here are some of the ones I have found. Please only contribute sites to the not-free section that you have actually done business with (and think deserve a link.)

• Agilent Manual Search - http://www.home.agilent.com/agilent/facet.jspx?lc=eng&cc=US&t=80039.k.1&pageMode=TM
  • Mostly newer equipment.
  • They also have an FTP site at ftp://ftp.agilent.com/pub/manuals/
• HP Archive manuals page - http://www.hparchive.com/hp_equipment.htm
• BAMA (BoatAnchor Manual Archive) - http://www2.faculty.sbc.edu/kgrimm/boatanchor/
• Various Scans of HP Manuals, etc. - http://www.kennethkuhn.com/hpmuseum/scans/
  • Lots of military manuals for HP test equipment, I found an elusive manual here. — jeff 12/24/2010 20:56
• K7JRL manuals - http://www.k7jrl.com/pub/manuals/
• ElecktroTanya - Insanely hard to navigate, confusing website, but they seem to have a lot of manuals. Limit 2 per day for unregistered users. Mostly in Hungarian, use Google translate.
• KO4BB's Manuals Repository - http://www.ko4bb.com/manuals/

• ArtekMedia - http://www.artekmedia.com/
  • HP, Agilent, Tek, others. I purchased a manual for an old, obscure HP power supply, and when I had problems opening the pdf they were extremely helpful (and created a new scan for me). Reasonable prices, very high quality scans. — jeff 12/24/2010 20:31
