6 Installation Note E8356-90052
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 havinga1MΩresistor 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.

Installation Note E8356-90052 7
Overview of the Installation Procedure
Note that step 2 is necessary only for the E8356A network analyzer because it requires a new
A12 source assembly.
1. Verify the serial and option numbers of the analyzer.
2. Replace the A12 source assembly (E8356A only).
3. Enter the new model number.
4. Verify that the new model number is shown correctly.
5. Replace the model number nameplate on the front panel.
6. Perform source and receiver calibration adjustments.
Tools and Equipment Required for the Installation
Step 1. Verify the Serial and Option Numbers of the Analyzer
Refer to the License Key Certificate supplied with the kit:
• Verify that the analyzer’s serial number matches the serial number on the certificate.
• Verify that the option number on the certificate is either 1F6 (for a 6 GHz upgrade) or
1F9 (for a 9 GHz upgrade).
If either the serial number or the option number does not match the expected results, you will
not be able to install the option. If this is the case, contact Agilent for assistance. Refer to
“Getting Assistance from Agilent” on page 5.

Step 2. Replace the A12 Source Assembly (E8356A Only)
This step is necessary only for the E8356A network analyzer. If installing an upgrade kit for
the E8357A network analyzer, proceed to Step 3.
Remove the Outer and Inner Covers from the Analyzer
Refer to Figure 2 for this procedure.
Remove the Outer Cover
CAUTION This procedure is best performed with the analyzer resting on its front handles
in the vertical position. Do not place the analyzer on its front panel without the
handles. This will damage the front panel assemblies.
1. Disconnect the power cord (if it has not already been disconnected).
2. With a T-20 TORX driver, remove the strap handles (item ①) by loosening the screws
(item ②) on both ends until the handle is free of the analyzer.
3. With a T-20 TORX driver, remove the four rear panel feet (item ③) by removing the center
screws (item ④).
4. Slide the four bottom feet (item ⑤) off the cover.
5. Slide the cover off of the frame.
Remove the Inner Cover
1. With a T-10 TORX driver, remove the 15 screws (item ⑥).
2. Lift off the cover.

10 Installation Note E8356-90052
Replace the A12 Source Assembly
Refer to Figure 3 for this step.
1. Place the A31 hard disk drive assembly in the service position.
a. With a T-10 TORX driver, remove the mounting screw (item ①).
b. Move the HDDA to the outside of the analyzer and slide the HDDA bracket feet into the
slots on the frame to the horizontal position. This is the service position.
Figure 3 Placing the A31 HDDA in the Service Position
Refer to Figure 4 for the following steps.
2. Disconnect the three flexible cables (item ①) from the A12 source assembly being careful
to note their locations for reconnection later.
CAUTION Be careful not to damage the center pins of the semirigid cables. Some flexing of
the cables is necessary to remove the assembly. Do not over-bend the semirigid
cables.
3. With a 5/16-in torque wrench, disconnect the semirigid cable (item ②) from the bottom of
the A12 source assembly.
CAUTION To avoid damage to the semirigid cable (item ②), pull down on the cable from the
bottom of the analyzer to move it away while sliding out the A12 source
assembly. The cable has some spring to it and the RF pin could be damaged by
the A12 source assembly.
4. Slide the A12 source assembly out of the analyzer.
5. Slide the new A12 source assembly into the analyzer being careful not to damage the
semirigid cables. Refer to the CAUTIONs above.

Installation Note E8356-90052 11
6. With a 5/16-in torque wrench, reconnect the semirigid cable (item ②) to the bottom of the
A12 source assembly.
7. Reconnect the three flexible cables (item ①) to the A12 source assembly.
Refer to Figure 3 for the following steps.
8. Reinstall the A31 hard disk drive assembly into its original position.
9. With a T-10 TORX driver, replace the mounting screw (item ①)

Reinstall the Inner and Outer Covers
Refer to Figure 5 for this procedure.
Reinstall the Inner Cover
1. Place the inner cover on the analyzer. There are two alignment pins on the front frame
that must be aligned with holes in the cover.
2. With a T-10 TORX driver, install the 15 screws (item ①).
Reinstall the Outer Cover
CAUTION This procedure is best performed with the analyzer resting on its front handles
in the vertical position. Do not place the analyzer on its front panel without the
handles. This will damage the front panel assemblies.
1. Slide the cover onto the frame.
2. With a T-20 TORX driver, install the four rear panel feet (item ②) by installing the center
screws (item ③).
3. Slide the four bottom feet (item ④) onto the cover.
4. With a T-20 TORX driver, install the strap handles (item ⑤) by tightening the screws
(item ⑥) on both ends.

Installation Note E8356-90052 17
Step 6. Perform Source and Receiver Calibration Adjustments
The following adjustments must be made due to the change in the full frequency range of the
analyzer.
Source Calibration Adjustment
The source calibration is used to adjust your network analyzer for a flat source power across
its full frequency range. The differences between Port 1 and Port 2 are negligible; therefore, a
Port 2 adjustment is not required.
1. Connect the equipment as shown in Figure 7. Connect a GPIB cable between the network
analyzer and the power meter.
Figure 7 Setup for the Source Calibration Adjustment
2. On the System menu, point to Service,Adjustments, then click Source Calibration.
3. Ensure the GPIB settings are correct.
4. Click Calibrate, then follow the instructions as they are displayed.

18 Installation Note E8356-90052
Receiver Calibration Adjustment
The receiver calibration is used to adjust the network analyzer receivers for a flat response
across its full frequency range. A power meter is connected to Port 1, as shown in
Figure 8, to establish a reference for flatness. A signal from Port 1, as shown in
Figure 9, is used to adjust the “B” receiver at Port 2. The adjustment is repeated using a
signal from Port 2 to adjust the “A” receiver at Port 1.
1. Connect the equipment as shown in Figure 8. Connect a GPIB cable between the network
analyzer and the power meter.
Figure 8 Setup for the Receiver Calibration Adjustment
Figure 9 Setup for the Receiver Calibration Adjustment of Port 2
2. On the System menu, point to Service,Adjustments, then click Receiver Calibration.
3. Ensure the GPIB settings are correct.
4. Click Calibrate, then follow the instructions as they are displayed.

Installation Note E8356-90052 19
Performance Tests and System Verification
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
“Getting Assistance from Agilent” on page 5.
Although the analyzer functions, its performance relative to its specifications has not been
verified for the additional frequency range enabled by this upgrade.
It is recommended that a full instrument calibration be performed using the N2721A
performance test software.
If the testing of the analyzer’s full range of specifications is not required, a system verification
can be performed.
Refer to the analyzer’s service guide for information on performance tests and system
verification.
