Installation Procedure for the Upgrade Kit
The network analyzer must be in proper working condition prior to installing this option. Any
necessary repairs must be made before proceeding with this installation.
WARNING This installation requires the removal of the analyzer’s protective outer
covers. The analyzer must be powered down and disconnected from the
mains supply before performing this procedure.
Electrostatic Discharge Protection
Protection against electrostatic discharge (ESD) is essential while removing or connecting
cables or assemblies within the network analyzer.
Static electricity can build up on your body and can easily damage sensitive internal circuit
elements when discharged. Static discharges too small to be felt can cause permanent
damage. To prevent damage to the instrument:
•always wear a grounded wrist strap having a 1 MΩresistor in series with it when handling
components and assemblies.
•always use a grounded, conductive table mat while working on the instrument.
•always wear a heel strap when working in an area with a conductive floor. If you are
uncertain about the conductivity of your floor, wear a heel strap.
Figure 1 shows a typical ESD protection setup using a grounded mat and wrist strap. Refer to
“Tools and Equipment Required for the Installation” on page 7 for part numbers.

2. With a T-20 TORX driver, remove the four rear panel feet (item {) by removing the center
screws (item |).
3. Slide the four bottom feet (item }) off the cover.
4. With a T-20 TORX driver, remove the strap handles (item ~) by loosening the screws
(item ) on both ends until the handle is free of the analyzer.
5. Slide the cover off of the frame.

Step 2. Replace (if necessary) Cables W20 and W21
Refer to Figure 3 and Figure 4.
1. Place the analyzer top-side up.
2. With a T-10 TORX driver, remove the 11 screws (item {) used to attach the inner cover
and lift off the inner cover.
3. Examine the part number labels on cables W20 (connected to A8J106) and W21 (connected
to A8J101).
• If the part numbers are E8361-20045 and E8361-20046 respectively, then they do not
need to be replaced. Proceed to step 5 on the next page.
• If the part numbers ARE NOT E8361-20045 and E8361-20046 respectively, they need to
be replaced. Continue at step 4 on the next page.

Enable Option 016
1. On the analyzer’s System menu, point to Service, and then click Option Enable.
2. In the Select Desired Option list, click 016 - Receiver Attenuators.
3. Click Enable.
4. Click Yes in answer to the displayed question in the Restart Analyzer? box.
5. When the installation is complete, click Exit.
Verify that Option 016 is Enabled
1. On the analyzer’s Help menu, click About Network Analyzer.
2. Verify that “016” is listed after “Options:” in the display.

20 Installation Note E8361-90003
Step 11. Perform Post-Upgrade Adjustments and Calibration
Adjustments
The following adjustments must be made due to the change in the full frequency range of the
analyzer.
• source calibration
• phase lock IF gain
• receiver calibration
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 can be found at “Test Equipment
Required for Post-Upgrade Adjustments” on page 7.
Calibration
The analyzer should now operate and phase lock over its entire frequency range.
If you experience difficulty with the basic functioning of the analyzer, contact Agilent. Refer to
“Contacting Agilent” on page 3.
• Although the analyzer functions, its performance relative to its specifications has not been
verified.
• It is recommended that a full instrument calibration be performed using the PNA
performance test software.
• Refer to the analyzer’s service guide for information on the performance test software.
