Recently i aquired a E4411A analyzer at auction, the unit does not have any options installed but came with a 3.5" Floppy labeled ESA Phase noise measurement personality Option 226, rev B.01.13 E4401-10017 ! I checked the website for a manual and found that this SW requires a license key to be entered but there is no certificate of any kind with the analyzer, who can i contact to get the key ? do i need the analyzer S/N it will be installed on ?
