I come from CHINA.There is an old 54815A Infiniium Oscilloscope in our company. The operation system is Windows 98. Now the Infiniium Software was lost. The oscilloscope is an old type. Agilent do not provide any technique support any more. I can only downlord the software"SetupInfiniium0421" which is for Windows 2000 at least in the website of Agilent. So I hope anybody would like provide me the software if possible. My email: email@example.com. Thanks!
