Installation Procedure for the Upgrade
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.
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.
Overview of the Installation Procedure
“Step 1. Obtain a Keyword and Verify the Information.”
“Step 2. Remove the Outer Cover.”
“Step 3. Remove the Inner Cover.”
“Step 4. Remove the Front Panel Assembly.”
“Step 5. Remove the Existing Test Set Cables.”
“Step 6. Remove the Existing Attenuators, Brackets, and Bias Tees (If
Present).”
“Step 7. Assemble the Old Attenuators and the New A52 and A53 Bypass
Switches onto the New Brackets.”
“Step 8. Install the New Brackets, with the Old Attenuators and the New A52
and A53 Bypass Switches, into the Analyzer.”
“Step 9. Assemble the A29 and A32 Test Port Coupler Assemblies (For
Analyzers with Serial Numbers Prefixed MY/SG/US5310 and Below).”
“Step 10. Install the New (3.5 mm) A29 and A32 Test Port Couplers onto the
Front Plate (For Analyzers with Serial Numbers Prefixed MY/SG/US5310 and
Below).”
“Step 11. Assemble and Install the A54 Bridge and A55 Noise Down
converter.”
“Step 12. Install the A7 Noise Receiver Board.”
“Step 13. Install the Bulkhead Connectors in the Test Set Front Plate (For
Analyzers with Serial Numbers Prefixed MY/SG/US5310 and Below).”
“Step 14.Install the New Test Set Cables.”
“Step 15. Replace the A16 Power Supply (If Necessary).”
“Step 16. Replace the lower front panel overlay.”
“Step 17.Reinstall the Front Panel Assembly and Front Panel Jumpers.”
“Step 18. Position the Cables and Wires to Prevent Pinching.”

Installation Procedure for the Upgrade
“Step 19. Reinstall the Inner Cover.”
“Step 20. Reinstall the Outer Cover.”
“Step 21. Enable Option 029.”
“Step 22. Verify Option 028 is Not Installed.”
“Step 23.Perform Post-Upgrade Adjustments and Calibration.”
“Step 24. Prepare the PNA for the User.”
Step 1.Obtain a Keyword and Verify the Information
Follow the instructions on the Option Entitlement Certificate supplied to obtain
a license key for installation of this upgrade. Refer to “License Key
Redemption” on page 5.
Verify that the model number, serial number, and option number information
on the license key match those of the instrument on which this upgrade will be
installed.
If the model number, serial number, or option number do not match those on
your license key, you will not be able to install the option. If this is the case,
contact Keysight for assistance before beginning the installation of this
upgrade. Refer to “Contacting Keysight” on page 4.
Once the license key has been received and the information verified, you can
proceed with the installation at step 2.
Step 2. Remove the Outer Cover
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 1 for this step of the procedure.
1. Disconnect the power cord (if it has not already been disconnected).
2. Remove the strap handles (item ①) by loosening the screws (item ➁), with
a T-20 TORX driver, on both ends until the handle is free of the analyzer.
3. Remove the foot locks (item ③) from the four bottom feet (item ④) and
then remove the four bottom feet from the outer cover.
4. Remove the four rear panel feet (item ⑤) by removing the center screws
(item ⑥) with a T-20 TORX driver.
5. Slide the outer cover toward the rear of the analyzer and remove it.

Refer to Figure 3 for this step of the procedure.
1. With a 5/16-in wrench, remove all front panel jumpers (item ①).
2. With a T-10 TORX driver, remove the screws (item ➁) from the sides of the
frame.
Before removing the front panel from the analyzer, lift and support the
front of the analyzer chassis.
3. Slide the front panel over the test port connectors.
4. Disconnect the front panel interface ribbon cable (item ③). The front panel
is now free from the analyzer.

Step 5.Remove the Existing Test Set Cables
Be careful not to damage the center pins of the semirigid cables. Some
flexing of the cables may be necessary but do not over-bend them.
Leave the gray flexible cables, the wire harnesses, and the ribbon cables
connected where possible. Any that are removed should be labeled for
reconnection later.
Refer to Figure 4 for this step of the procedure. Although only Option 419 is
shown in the illustration, Option 423 is similar in appearance.
1. Place the analyzer bottom-side up on a flat surface.
2. Remove the following cables in the order listed. Discard these cables; they
will not be reused.

Step 6.Remove the Existing Attenuators, Brackets, and Bias Tees (If
Present)
Refer to Figure 5 for this step of the procedure. Although only Option 419 is
shown in the illustration, Option 423 is similar in appearance.
1. Place the analyzer bottom-side up on a flat surface.
If bias tee option is installed (NOT N5241/42A-H85):
For analyzers with serial numbers prefixed MY/SG/US5321 and above:
2. Remove two screws (item ①) from the A38 port 1 bias tee and the A41
port 2 bias tee and lift them out of the PNA, and set them aside for
reinstallation later.
For analyzers with serial numbers prefixed MY/SG/US5310 and below:
3. Remove two screws (item ①) from the A38 port 1 bias tee and the A41
port 2 bias tee and lift them out of the PNA. These old bias tees have 2.4
mm connectors and will be replaced later with bias tees having 3.5 mm
connectors.
For all analyzers:
4. Remove three screws (item ➁) from each attenuator bracket.
5. Remove the attenuator brackets, with the attenuators still attached, from
the analyzer.
6. If it is necessary to remove any other cables from the analyzer to facilitate
