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.

Step 1. 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.
Refer to Figure 2.
1. Disconnect the power cord (if it has not already been disconnected).
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.
Figure 2 Outer Cover Removal
NOTE The figure above shows the E8361A front panel and floppy disk drive. The
E8361C front panel has a slightly different appearance and does not
include a floppy disk drive.

Installation Note E8361-90003 9
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.

b. Remove the cable hold-down wire (item |).
c. Disconnect cables W20 and W21 at both ends; two top side connections and two bottom
side connections. Remove the cables from the analyzer.
d. Position the new cables in the analyzer and connect them as follows: W20–A8J106 to
A17J2; W21–A8J101 to A17J3. Tighten the connectors to 10 in-lbs.
e. Reinstall the cable hold-down wire (item |).
