Licenses
NOTE If your instrument has A.01.50 firmware loaded, two years after purchase, your MXG can
display the following time- based error message: "AUS license expires in xxd days.
Contact Agilent Technologies to renew." The error message will repeat three times over
90 days (e.g. first at 90- 60 days remaining, second at 59- 30 days remaining, and the last at
30- 0 days remaining days).
This message can be ignored. This error does not indicate a performance problem with your
MXG. Pressing any softkey will clear the message and the instrument can be used normally.
Downloading a newer version of firmware will prevent further AUS license- related error
messages being displayed.
