MP4300 Series Firmware
NOTE:
To upgrade from 1.X.X to 2.1.03 or later you must first update to 2.0.01 (transition). To upgrade from 1.0.12 or 1.1.09 to 2.0.01 (transition) you must first update to 1.3.20.
To downgrade to 2.0.01 from 2.1.03 or later, you must use the image 2.0.01 (non-transition).
After upgrade to 2.x.x firmware, direct downgrade to 1.3.20 and earlier FW revisions is not possible - contact Keysight support if downgrade required.
After upgrade to 2.x.x firmware, all non-volatile settings will be lost (digital I/O, group settings, etc.- see Operating and Service Guide)
Keysight recommends using the most current version, which includes the most up-to-date bug fixes and security patches available.
