Description of the Upgrade
Installation Procedure for the Upgrade

— IF Response Adjustment (Options 090, 093, or 094 Only.)
— Noise Adjustment (Option 029.)
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 is also

found in the service guide.
To view this service guide information, click the Chapter 3 bookmark “Tests
and Adjustments” in the PDF Service Guide

After the specified adjustments have been performed, the analyzer should

operate and phase lock over its entire frequency range.

Operator’s Check

Perform the Operator’s Check to check the basic functionality of the analyzer.

For instructions, click the Chapter 3 bookmark “Tests and Adjustments” in the
PDF Service Guide

If you experience difficulty with the basic functioning of the analyzer, contact

Keysight. Refer to

“Contacting Keysight” on page 4

Calibration

Although the analyzer functions, its performance relative to its specifications

has not been verified. It is recommended that a full instrument calibration be

performed using the analyzer’s internal performance test software. To view

information on the performance test software, click the Chapter 3 bookmark
“Tests and Adjustments” in the PDF Service Guide

Step 23. Prepare the PNA for the User

If necessary, reinstall front jumper cables.

Install the cable guards, pushing them over the front jumper cables until

the cushioning material touches the front panel of the PNA.

Install the dust caps on the test ports.

Clean the analyzer, as needed, using a damp cloth.
