Installation Note
Description of the Upgrade
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.
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.

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.
To successfully install this upgrade kit, you will need the following:
—A license key - refer to “License Key File Redemption” below.
— A PDF copy or a paper copy of the PNA Service Guide - refer to
— An ESD-safe work area - refer to “Protecting Your Workspace from
— Correct tools - refer to “Tools Required for the Installation” on page 6.

License Key File Redemption
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.
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.

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.
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.
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
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.
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 Guide

.
These cables may be discarded - they will not be reinstalled.

— The Network Analyzer program must not be running.
— Refer to the license message you received from Keysight: Verify that the
analyzer’s model and serial numbers match those on the license message
you received from Keysight.
— Obtain a license key (A models) or license key file (B models) for installation
of this upgrade by following the instructions on the supplied Software
Entitlement Certificate.
— A keyboard must be connected to the network analyzer.
For "A" models, refer to “Option Enable Procedure for "A" Model Instruments”
on page 28.
For "B" models refer to “Option Enable Procedure for "B" Model Instruments ”
on page 29.

Option Enable Procedure for "B" Model Instruments
For this step, you will need a USB flash drive.
A single license file may contain more than one feature.
1. Locate the email(s) from Keysight which contain license file attachments.
These emails are a result of Step 3 on “License Key File Redemption” on
page 4.
2. Copy the license file(s) from the email(s) to the root directory of the USB
flash drive.
More than one license file may be copied to the USB flash drive.
A license file may contain more than one feature.
3. Verifying and editing the license file:
For these steps, refer to the example in Figure 12 on page 30.
a. Verify your USB flash drive is connected to a PC.
b. Open your license file using a text read/write program similar to
Notepad.
c. If you have more than one licensed feature, delete the feature that is
not required for this upgrade. (e.g., in this case N5242B-423 is the
correct upgrade. So, N5242B-422 is to be deleted from the text file.)

4. Connect the USB flash drive to the PNA. Within 5 seconds, the PNA
should display a small "New licenses installed" message.
Else, load the license key file(s), manually move your license file(s) to
C:\Program Files\Agilent\ licensing. It may take Keysight License
Manager an extra ~5 seconds to enable the licenses.
Attempting to re-install a license file that is already installed may generate
a “Corrupt Media” error message. Ignore this message.
5. Disconnect the USB flash drive from the PNA.

Step 19.Perform Post-Upgrade Adjustments and Calibration
Adjustments
The following adjustments must be made due to the hardware changes of the
analyzer.
—source adjustment
— IF gain adjustment
— receiver characterization
—receiver adjustment
— IF Response adjustment (For A model: Options 090, 093, or 094 Only. For B
models: Options S93090xA/B, S93093A/B, or S93094A/B Only.)
— Noise adjustment (For N5244/5B models: Option 029 with S93029A/B
Only.)
These adjustments are described in the PNA Service Guide and in the PNA
on-line HELP. A list of equipment required to perform these adjustments is also
found in the service guide.
