4 Post-Repair Procedures and Performance Verification
Post Repair Procedures
CAUTION After changing an assembly, but before performance verification, Agilent recommends that the most recent firmware is
loaded into the instrument.
To avoid internal calibration failures and potential post-repair errors, before removing any instrument assembly, the
instrument’s static and dynamic arrays must be configured for the exchange of assemblies. The process to do the appropriate
configuration is performed automatically by the MXG with the Assembly Installation and Removal Overview front panel
softkeys. Refer to the Assembly Installation and Removal Overview and to the “Hardware Assembly Installation and
Removal Softkeys” on page 4-2.
For the instrument to meet performance specifications and for accurate self-test results, allow a warm up period of 45 minutes
within an operational temperature range of 0 to 55 °C. For more information, refer to the MXG signal generator Data Sheet.
The ability to ensure proper hardware compatibility when an assembly is replaced in the MXG, is based on the capability of the product to
save and reconfigure its arrays. To ensure that existing and new hardware is appropriately configured correctly, the static and dynamic arrays
associated with the different assemblies must be modified as needed.
The process to do the appropriate configuration is performed automatically by the MXG with the Assembly Installation and Removal
Overview front panel softkeys.
The corresponding assembly removal softkey is pressed once prior to a specific assembly being permanently removed for replacement from
the instrument. Once the removed assembly has been permanently replaced the corresponding installation softkey is pressed, completing the
hardware and installation.
