Steve, Flight Safety? I got my Private Pilot's license in 1968, an ATP in 1992, and now about 4500 hours later I am still flying. I did find a 3458A that should be here next week. It was advertised as fully functional and comes with a 30 day return guarantee. For what I paid, I will be able to return it to Agilent for repair and still be ahead of what I have seen on theBay. Hopefully, all it will need is a return for alignment/calibration. If Solartron is 'on schedule', I should have the 7081 back before Thanksgiving. I just hope there is not hidden disaster that makes it useless. I got the paper manuals today for the 7081 and they appear to be in good condition but I am a little suspicious that they are copies rather than original. But very good condition and very legible.

Unfortunately it involves a lot of travel as I'm the interface with the aviation authorities around the globe. My 7081 is sitting on the bench warming up and I hope to do some comparisons against the 3458A before I get called out of the country again. I hope they provide a good report with the return of your meter. Let us know how it turns out. Best regards, Steve On 10/4/2011 9:53 PM, J. L.

Joe, Is your paper manual differ from the PDF-versions in the web? Are they contain the Service Manual (not Maintenance Manual)? Mickle T.

Mickle, I have not had a chance to compare it page by page but it is the Maintenance Manual, part number 70810014, Issue 5: August 1986, just like the .PDF copy on the web. Only it is much more legible. The Operating Manual Part I is part number 70810010, like the .PDF on the web, but it is a different issue, Issue 7: July 1994. Again, I have not compared it page by page but it looks the same. The Operating Manual Part II is part number 70810011, Issue 5: June 1985, like the .PDF on the web.
