Important Information
If the upgrade being installed is Option A4H, GPIB/Parallel or Option 1AX, RS-232/Parallel, the instrument firmware may need to be upgraded.
Firmware Revision Verification for Upgrade Options A4H and 1AX
Instructions for all ESA Spectrum Analyzers (E4401B, E4402B, E4403B, E4404B, E4405B,
E4407B, E4408B, E4411B):
NOTE If you have upgraded an EMC analyzer with GPIB/Parallel or RS-232/Parallel (E7401A,
E7402A, E7403A, E7404A, or E7405A) go to the section “Instructions For All EMC
Analyzers (E7401A, E7402A, E7403A, E7404A, E7405A)”
below

2. Press System , More , Show System . Make a note of the firmware revision and see if Option B72,
Expansion Memory, is listed on the display.
3. If Option B72 is installed, the firmware revision MUST be A.12.00 or greater. If the firmware revision is A.12.00 or greater, you can proceed to the performance and functional testing for the upgrade being performed. If the firmware revision is less than A.12.00, the firmware MUST be upgraded to the latest version using one of the following methods:
• Download the instrument firmware via the world-wide web at http://www.agilent.com/find/esa_firmware. This entire process of upgrading firmware will take approximately 45 minutes.
• Receive the latest firmware upgrade disk set by ordering upgrade Option UE2.
4. If Option B72 is not installed, you should upgrade the instrument firmware to the latest version for instruments that do not have Option B72 installed using one of the following methods:
• Download the instrument firmware via the world-wide web at http://www.agilent.com/find/esa_firmware_std-mem. This entire process of upgrading firmware will take approximately 45 minutes.
