About Installing the Upgrade Kit
Description of Option 014
An Option 014 analyzer can be configured to measure high-power devices and devices for high
dynamic range.
For a high-power measurement, external amplifiers and high power attenuators or isolators
can be added to complete the test setup. In this configuration, test port output power up to
1 Watt (+30 dBm) can be applied to the device under test (DUT). Additionally, there is an
external reference input that allows the external amplifier’s frequency response and drift to
be ratioed out.
For high dynamic range measurements, front panel jumpers are moved to reverse the signal
path through one of the couplers. This allows for a 15 dB improvement in transmitted signal
sensitivity in one direction only. These jumpers are installed on both ports allowing the user
to choose a high dynamic range measurement in either the forward or reverse direction.

6Installation Note E8364-90012
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 for this procedure.
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.

Installation Note E8364-90012 9
Step 2. Remove the Front Panel Assembly
Refer to Figure 3 for this procedure.
1. With a T-10 TORX driver, remove the eight screws (item ①) from the sides of the frame.
CAUTION Before removing the front panel from the analyzer, lift and support the front of
the analyzer chassis.
2. Slide the front panel over the test port connectors.
3. Disconnect the front panel interface ribbon cable (item ②). The front panel is now free
from the analyzer.

16 Installation Note E8364-90012
Step 7. Replace the Lower Front Panel Overlay
NOTE The new parts referenced in this procedure are listed in Table 1 on page 5.
Refer to Figure 10 for this procedure.
1. From the back side of the front panel, use a blunt object in one of the cutouts in the lower
frame to push the overlay (item ①) and separate it from the front panel.
2. From the front side of the front panel, pull the overlay completely off and discard it.
3. Remove any adhesive remaining on the front panel.
4. Remove the protective backing from the new front panel overlay (item ①). Note that there
are two overlays provided; one for Option 014 only and one for Option 014 in combination
with Option UNL. Make sure you install the proper one for your analyzer:
• The Port 1 and 2 SOURCE OUT labels for the Option 014 only overlay reads 40 VDC.
• The Port 1 and 2 SOURCE OUT labels for the Option UNL/014 overlay reads 0 VDC.
5. Starting from either the left or right side, loosely place the overlay in the recess on the
lower front panel, ensuring that it fits tightly against the recess edges.
6. Once the overlay is in place, press it firmly onto the frame to secure it.

Installation Note E8364-90012 17
Step 8. Reinstall the Front Panel Assembly and Install the Front Panel
Jumpers
CAUTION Before installing the front panel assembly onto the analyzer, lift and support the
front of the analyzer chassis.
Refer to Figure 11 for this procedure.
1. Tighten all 12 of the front-panel feed-through connectors using a 5/16-in torque wrench set
to 21-in lbs.
2. Reconnect the ribbon cable (item ①) to the A3 front panel interface board.
3. Slide the front panel over the test port connectors being careful to align the power switch
and floppy disk drive to their corresponding front panel cutouts. Ensure that the ribbon
cable ①is located below the fan to prevent it from being damaged by the fan blades.
4. With a T-10 TORX driver, install the eight screws (item ②) in the sides of the frame.
5. Install the six semirigid jumpers (item ③) on the front panel and tighten to 10-in lbs.

18 Installation Note E8364-90012
Step 9. 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.
Refer to Figure 12 for this procedure.
1. Slide the cover over the analyzer frame.
2. With a T-20 TORX driver, install the four rear panel feet (item ①) by installing the center
screws (item ②).
3. Slide the four bottom feet (item ③) into position on the cover.
4. With a T-20 TORX driver, install the strap handles (item ④) by installing the screws
(item ⑤) on both ends of the handle.

Step 11. Perform Post-Upgrade Adjustments and Calibration
The following adjustments must be made due to the change in the full frequency range of the
analyzer.
• source calibration
• 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 “Equipment
Required for Post-Upgrade Adjustments” on page 7.
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 3.
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.
