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
The instrument must be readjusted and the performance tested to assure the instrument meets
specifications following the hardware installation. The X-Series Performance Verification and
Adjustment Software must be used. All adjustments are automated. This software is included in
the N7814A, Keysight X-Series Signal Analyzer Calibration Application software.

Initial Instrument Functionality Check
Power on the instrument and allow the instrument to boot up. Run an alignment and display the
measurement screen. (The instrument will probably display a spectrum analyzer screen and you will
see the instrument sweeping.)
There should be no alignment failures. If there are failures, investigate and fix the problem before
continuing.
Before you disassemble the instrument, turn the power switch to Standby. After the instrument
has completely shut down, unplug the instrument. Failure to unplug the instrument can result in
personal injury.
Electrostatic discharge (ESD) can damage or destroy electronic components. All work on
electronic assemblies should be performed at a static-safe workstation. Refer to the
documentation that pertains to your instrument for information about static-safe workstations
and ordering static-safe accessories.

Analyzer Information
1. Connect a power cord to the analyzer and turn on the analyzer.
2. After the analyzer has completed turning on, press System, Show System. Make note of the
following information from the Show System screen:
Product Number ________________
Serial Number ________________
Instrument S/W Revision ________________
3. Check for the presence of the options listed below in the Show System screen. Put a check
mark or “X” after each option listed below that appears in the Show System menu.
N9020B-503 ______
N9020B-508 ______
N9020B-513 ______
N9020B-526 ______
N9020B-BBA ______
N9020B-B40 ______
N9020B-DP2 ______
N9020B-MPB ______
Refer to the following conditions:
—If the analyzer is not equipped with N9020B-B40, do not proceed with the installation of
this upgrade kit. If N9020B-B40 is not installed, other upgrade kits are available to upgrade
to 85 MHz, 125 MHz, or 160 MHz analysis bandwidth.
—If the analyzer has N9020B-BBA, do not proceed with the installation of this kit. N9020B
analyzers with Option BBA do not have sufficient room to install the two additional boards
required for analysis bandwidths of 85 MHz and wider.
—If the N9020B-MPB is not already present and either frequency range option N9020B-508,
N9020B-513, or N9020B-526 is present, it will be necessary to upgrade the analyzer to add
option N9020B-MPB before installing this kit. Refer to
http://www.keysight.com/find/mxa_upgrades for details on how to upgrade to N9020B-
MPB.
Do not attempt to install this kit on an N9020A. Although much of the hardware is identical, the
licenses included in this kit will only work on an N9020B.

Installation Procedure
Update Instrument Software
Updating the instrument software and installing the necessary licenses before installing the new
hardware will help ensure that the hardware installation was successful.
Go to the following website and determine whether or not the analyzer has the latest instrument
software already installed:
http://www.keysight.com/find/xseries_software
If the analyzer does not have the latest instrument software already installed, download and install
the latest version.

Installation Procedure
Licensing the New Options
License Installation Procedure over USB
1. Locate the Option Upgrade Entitlement Certificate (5964-5178) in the kit.
2. Redeem the Option Upgrade Entitlement Certificate by following the instructions on the
Certificate.
3. After redeeming the upgrade products from the Certificate(s), you will receive one or two
e-mails, each with an attached License File.
4. Locate a USB storage device. Perform a virus scan on this device before use.
5. Save the License File(s) to the root directory of the USB Storage Device.
6. Connect the USB Storage Device to one of the analyzer’s USB ports. Connect a mouse to
another USB port. Windows will detect the new hardware and may display the configuration
menu shown in Figure 1. This menu may be configured according to your preferences.
Figure 1 USB Storage Device Configuration Menu

10 Installation Note N9020-90254
Installation Procedure
7. The signal analyzer will automatically consume the License File. (This may take a few minutes)
When the License File is consumed the Keysight License Manager will display a “Successful
License Installation” message similar to the one shown in Figure 2. If the license file contains
multiple licenses, multiple “Successful License Installation” messages will appear. Wait until
all licenses have been consumed before removing the USB Storage Device.
Figure 2 Successful License Installation
If you will also be installing any of the following upgrade products:
N9020BU-MPB
N9020BU-CR3, 2nd IF Output
N9020BU-CRP, Arbitrary IF Output
Now would be the best time to install the licenses for these other upgrades. By installing the
licenses now, the adjustments and performance verifications for these other upgrades will also
be performed.
