Hey, Win:-

We had a mechanical encoder failure on a 33220A arb function
generator. It is a known issue with these encoders and Agilent sent a
repair kit gratis (or we could have sent it in). It's an easy fix, so
I elected to do it myself.


Here's the service note:

The expiration for free service or parts is February 1, 2012.
