Keysight Add Source and Receiver Attenuators Upgrade Kit
Upgrade Kit Number: N5225-60107
Installation Note
Description of the Upgrade
This upgrade adds the following items to your N5224A/B Option 401 or
N5225A/B Option 401 or N5244B Option 401 or N5245B Option 401 network
analyzer:
— a 60-dB source attenuator in each source port channel
— a 35-dB receiver attenuator in each receiver channel
— front panel overlay replacement
— new cables
After installation of this upgrade, your analyzer will be an N5224A/B Option
417 or N5225A/B Option 417 or N5244B Option 417 or N5245B Option 417.
Some of the assembly drawings in this document may be different from
your instrument, but the process is similar for both an "A" model and "B"
model instruments.
If you had an A model PNA-X with Option 219/419 with Option H85 that
was upgraded to a B model, please refer to Options 217/417. If you had an
A model PNA-X with Option 224/423 with Option H85 that was upgraded
to a B model then refer to Option 222/422.

Getting Prepared
To successfully install this upgrade kit, you will need the following:
—Alicensekey-referto“License Key File Redemption” below.
— A PDF copy or a paper copy of the PNA Service Guide - refer to
“Downloading the Online PNA Service Guide” below.
— An ESD-safe work area - refer to “Protecting Your Workspace from
Electrostatic Discharge” below.
— Correct tools - refer to “Tools Required for the Installation” on page 6.
— Enough time - refer to “About Installing the Upgrade” on page 6.
— Test equipment for the post-upgrade adjustments and full instrument
calibration. To view the equipment list, click the Chapter 3 bookmark “Tests
and Adjustments” in the PDF Service Guide1.
The PNA contains extremely sensitive components that can be ruined if
mishandled. Follow instructions carefully when making cable connections,
especially wire harness connections.
The person performing the work accepts responsibility for the full cost of
the repair or replacement of damaged components.

License Key File Redemption
To enable the option product, you must request license key(s) (A models) or
license key files(s) (B models) from the Keysight Software Manager:
http://www.keysight.com/find/softwaremanager.
To complete the request, you will need to gather the following information:
— From the certificate
— Order number
— Certificate number
— From your instrument
(Instrument information is available in the network analyzer - on the
toolbar, click Help, then click About Network Analyzer.)
— Model number
— Serial number
—A models ONLY: From the online Keysight HostID utility
Part of the OEC procedure to obtain the 12-digit license key online requires
you to provide the HostID number of the PNA. This HostID number is NOT
the one currently shown on the PNA. To find your new HostID, go to
http://www.na.support.keysight.com/pna/upgrades.html and, using the
HostID utility, enter the PNA serial number and your new, upgraded PNA-X
model number - N5224A, N5225A, N5244A, or N5245A.
—HostID
The only difference between an A model license key redemption and a B
model is that the A model uses a 12-character license key and the B model
uses a license key file.
Ensure that you are connected to an external server, before attempting to
download your email and license key file.
If you are unfamiliar with the licensing process:
For A models: Refer to
http://literature.cdn.keysight.com/litweb/pdf/N5225-90110.pdf.
For B models: Refer to
http://literature.cdn.keysight.com/litweb/pdf/N5242-90024.pdf.
The enclosed Software Entitlement Certificate is a receipt, verifying that
you have purchased a licensed option for the analyzer of your choice. You
must now use a Keysight Web page to request a license key email that
contains the license key files for the instrument that will receive the
option.

Installation Note N5225-90107 5
Description of the Upgrade
Getting Prepared
Using the information just gathered, you must request license key(s) for your A
model or for your B models, a license key file(s) from the Keysight Software
Manager: http://www.keysight.com/find/softwaremanager.
You will need to provide an email address, Keysight will promptly email your A
model license key(s) or a for a B model, license key file(s) attachment message.
Refer to “License Key File Redemption” on page 4.
Verify the License Contents
Refer to the license message you received from Keysight:
If the model number, serial number, or option number do not match those on
the license message you received from Keysight, you will not be able to install
the license key file. If this is the case, contact Keysight for assistance. Refer to
“Getting Assistance from Keysight” on page 3.

Description of the Upgrade
Installation Procedure for the Upgrade
-
Step 1. Obtain a Keyword and Verify the Information
Follow the instructions on the Software Entitlement Certificate supplied to
obtain a license key for installation of this upgrade. Refer to “License Key File
Redemption” on page 4.
Verify that the model number, serial number, and option number information
on the license key match those of the instrument on which this upgrade will be
installed.
If the model number, serial number, or option number do not match those on
your license key, you will not be able to install the option. If this is the case,
contact Keysight for assistance before beginning the installation of this
upgrade. Refer to “Contacting Keysight” on page 2.
Once the license key (A models) or license key file (B models) has been
received and the information verified, you can proceed with the installation at
“Step 2. Remove the Outer Cover” on page 10.
Step 2. Remove the Outer Cover
For instructions, click the Chapter 7 bookmark “Removing the Covers” in the
PDF Service Guide.
Step 3. Remove Some Bottom-Side (Test Set) Cables
1. Place the analyzer bottom-side up on a flat surface.
2. Remove the following cables. To see an image showing the location of
these cables, click the Chapter 6 bookmark “Bottom RF Cables, Standard
4-Port Configuration, Option 401” in the PDF Service Guide1.
These cables may be discarded - they will not be reinstalled.
— W12 (N5245-20109) A29 port 1 receiver coupler to W11
If the model number, serial number, or option number do not match those
on your license key (A models) or license key file (B models), you will not
be able to install the option. If this is the case, contact Keysight for
assistance before beginning the installation of this upgrade. Refer to
“Contacting Keysight” on page 2.
Leave the gray flexible cables, the wire harnesses, and the ribbon cables
connected where possible. Any that are removed should be labeled for
reconnection later.
Be careful not to damage the center pins of the semirigid cables. Some
flexing of the cables may be necessary but do not over-bend them.
