Description of the Upgrade
This upgrade extends the upper frequency limit of your 20 GHz configurable test set analyzer
(N5230A Option 225) to 40 GHz. This is done by installing Option F40. After installation of
this upgrade, your anlayzer will be an N5230A Option 425.
Option F40 provides the necessary 40 GHz components and cabling to allow your analyzer to
measure signals up to 40 GHz.

Installation Procedure for the Upgrade
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 have a grounded, conductive table mat in front of your test equipment.
•always wear a grounded wrist strap, connected to a grounded conductive table mat, having
a 1 MΩresistor in series with it, when handling components and assemblies or when
making connections.
•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.
•always ground yourself before you clean, inspect, or make a connection to a static-sensitive
device or test port. You can, for example, grasp the grounded outer shell of the test port or
cable connector briefly.
Figure 1 shows a typical ESD protection setup using a grounded mat and wrist strap. Refer to
“ESD Equipment and Supplies Required for the Installation” on page 6 for part numbers.

14 Installation Note N5230-90022
Step 6. Remove the 20 GHz Components
Refer to Figure 9 for this procedure.
1. Place the analyzer bottom-side up on a flat surface.
Remove the A17 MASS 26.5
2. Disconnect the ribbon cable (item ①) from the MASS 26.5. Leave this ribbon cable
attached to the A16 test set motherboard.
3. Disconnect the three flexible coaxial cables, W29–W31, from the MASS 26.5. Leave these
cables connected at the other end.
4. Remove the MASS 26.5 by removing the four attachment screws (item ②). Retain the
screws for installation of the A19 MASS 50.
Remove the A20 Mixer Brick
5. Disconnect the ribbon cable (item ③) from the mixer brick. Leave this ribbon cable
attached to the A16 test set motherboard.
6. Label, for re-connection later, the four flexible coaxial cables, W21–W24, that are
connected to the mixer brick. It is necessary to label these cables because they connect to
the A5 SPAM board on the top side of the analyzer and it is therefore difficult to trace their
connection path and location. Disconnect these four cables from the mixer brick but leave
them connected at the other end.
7. Remove the mixer brick by removing the four attachment screws (item ④). Retain the
screws for installation of the A20 50 GHz mixer brick.
