Hi Ian I dont know whether it works for that unit, but try the Hameg site. http://www.hameg.com/66.0.html There are "almost" complete manuals for all the units (well certainly the scopes!) You may find that there are no schematics in the English versions....download the German versions (which you may see are bigger files) and the are often schematics at the back of these....the titles etc are also bilingual.
Hope that helps Cheers de Alan G3NYK ----- Original Message ----- From: "Ian Sheffield" <[EMAIL PROTECTED]> To: <time-nuts@febo.com> Sent: Tuesday, July 22, 2008 7:51 AM Subject: [time-nuts] Hameg HM8125 Time/frequency Standard > Hello, > > Does anyone have a copy of a schematic or service manual for the down-converter for the Hameg HM8125 > GPS frequency/time receiver? > > The receiver and display seems to be working fine, but the separate down-converter appears to have been modified with a capacitor blocking the DC power feed from the receiver and what may be a voltage regulator has been removed.
