obsolete Agilent SA - how to upgrade?
Folks,
I got a nice Agilent E4401B spectrum analyzer for a bargain on Ebay,
only problem being the tightest resolution bandwidth is 1 kHz. Now for
that SA the upgrade to 10 Hz bandwidth is nothing more than typing in a
secret code. Problem is Agilent won't give you the code, the scope being
obsolete.
Anybody know of a third party solution, a hack, or ???
Thanks in advance --
