Installation Note
Description of the Upgrade
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.
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.
This upgrade converts your standard 2-port configurable test set analyzer
(N5244A/B Option 217 or N5245A/B Option 217) to an N5244/5A Option
222 or N5244/5B Option 222 and (N5244A/B Option 219 or N5245A/B
Option 219) to an N5244A/B Option 224 or N5245A/B Option 224 by adding:
— a second source assembly
— a second 13.5 GHz synthesizer board
—two additional doublers
— source outputs routed to the front panel
— source outputs routed to the rear panel
— a mechanical switch to each source port channel
— a source combiner to the port 1 channel
— rear-panel test set inputs

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 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 8.
“Downloading the Online PNA Service Guide” below.

License Key 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, refer to the
http://literature.cdn.keysight.com/litweb/pd f/N5242-90006.pdf
(A models) or
http://literature.cdn.keysight.com/litweb/pd f/N5242-90024.pdf
(B models).
The enclosed Software Entitlement Certificate is a receipt, verifying that
you have purchased a licensed option for the PNA of your choice. You must
now use a Keysight Web page to request a license key for the instrument
that will receive the option.
To enable the option product, you must request license key(s) 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
— Host ID (For B models the host ID is the model and serial numbers.)
Using the information just gathered, you must request license key(s) from the
Keysight Software Manager:
http://www.keysight.com/find/softwaremanager.
You will need to provide an email address, to which Keysight will promptly
email your license key file. Refer to “License Key Redemption” on page 6.
