Introduction
This procedure can be used to retrofit a 100 Hz Low Frequency Extension (Option UKB) into your analyzer.
This kit contains nameplates and connector labels for all models listed. Only one nameplate and one
connector label will be used for each model.
To ensure that this newly installed option is functioning properly, the procedure that follows includes the
requirement of performing certain adjustments and performance verification tests. However, the completion
of these tests does not guarantee that the instrument meets all advertised specifications.
Software is required to perform the required adjustments, and can be used to automate the performance
verification testing. Information on how to obtain this software can be found at:
www.agilent.com/find/calibrationsoftware
While Agilent does recommend that a full calibration be performed after the installation of this upgrade, the
end user must ultimately determine whether they want this service or not. If a full calibration is required,
arrangements regarding the level of calibration must be made between the end user and the calibration
provider.

Procedure
Verify A8A1 3 GHz RF Assembly Part Number
1. Turn on the analyzer and wait for the initial adjustments to complete.
2. Press System, More, Show Hdwr. This displays the Show Hardware screen, which lists the part number and
serial number of most of the installed board assemblies.
3. Locate the part number of the “50Ω3 GHz Input” assembly.
4. If the part number of the 50Ω3 GHz Input assembly is E4403-60033 or lower, the A8A1 3 GHz RF
assembly must be replaced. If the analyzer does not have the High Stability Frequency Reference,
Option 1D5, order E4403-60073. If the analyzer does have Option 1D5, order E4403-60074.
WARNING Before you disassemble the instrument, turn the power switch OFF and unplug the
instrument. Failure to unplug the instrument can result in personal injury.
CAUTION Electrostatic discharge (ESD) can damage or destroy electronic components. All work on
electronic assemblies should be performed at a static-safe workstation. Refer to the
documentation that pertains to your instrument for information about static-safe workstations
and ordering static-safe accessories.
