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

(N9020-60035), stop and send an email to [email protected] with the following details:

— 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.
