a.To ensure that this newly installed option is functioning properly, the procedure that follows includes the
requirement of performing certain adjustments and performance verification tests. However, the completion of
these tests does not guarantee that the instrument meets all advertised specifications.
Software and test equipment is required for making adjustments and for performance verification testing.
Information on how to obtain this software can be found at:
www.keysight.com/find/calibrationsoftware
While Keysight does recommend that a full calibration be performed after the installation of this upgrade, the
end user must ultimately determine whether they want this service or not. If a full calibration is required,
arrangements regarding the level of calibration must be made between the end user and the calibration
provider.

Introduction
You may have received a front frame replacement kit and a memory upgrade kit in addition to this
Option BBA upgrade kit. If so, it is recommended that you first verify the amount of RAM in the
analyzer by performing the following steps:
1. Turn the instrument on.
2. Verify that the Operating System can be found and that the Keysight Spectrum Analyzer
measurement application starts up and is sweeping.
3. Connect a USB mouse.
4. Verify the RAM size by going to the Start menu, right click on “My Computer”, and select
“Properties”. A window will pop up showing the computer properties. Under the General
information tab the RAM size will be listed.
If the analyzer has 1 GB of RAM, the memory upgrade must be performed. This upgrade should be
installed during the BBA upgrade when there is access to the processor board. Installing the
memory upgrade now will cause extra assembly time that is not necessary. The BBA upgrade
procedure below will identify the appropriate time to perform the memory upgrade.
If the analyzer identifies as having 1 GB of memory and you did not receive the memory upgrade kit
— Subject: “1 GB Memory Upgrade Kit (BBA Upgrade)”
— Instrument serial number that is being upgraded
— Complete ship to address, so we priority ship the memory upgrade
If the analyzer already has 2 GB of RAM, you do not need to perform the memory upgrade and can
begin converting the installation of the new front frame. Instructions for the front frame
replacement kit are located inside that kit.
This procedure is used to retrofit Option BBA into the N9020A Signal Analyzer.
Earlier vintages of analyzers had an LCD which uses slightly different mechanical parts. This
installation note addresses both the LCD and LED displays.
