[Moon-net] Help with HP8640A manual

[peter blair]

 I am halfway thru my tests on my 3.4 GHz transverter to make it cover 3456 MHz and my HP 8640A sig gen fails!! Does anyone out there have an electronic version of the manual ? Agilent dont have it on their site. I found a site a while ago that had a number of free HP manuals but cant now locate it. Help with either of these would be greatly appreciated.
