Assembly and Disassembly Procedures
Introduction
Introduction
Removing and replacing assemblies is straightforward. This chapter contains tool lists,
hints and drawings to help you do it effectively. Detailed step-by-step procedures are not
given for all assemblies.
After replacing certain assemblies you will need to load new calibration data into the HP/
Agilent8922 or perform adjustments. The calibration data is supplied on a Memory Card
that is included with the replacement assembly.
Referto chapter 9, “Replacing a Part”, for information about adjustments that are required
after replacing certain assemblies.
CAUTION Perform the following procedures only at a static safe work station. The printed circuit
assemblies in this instrument are very sensitive to STATIC ELECTRICITY DAMAGE.
Wear an anti-static wrist strap that is connected to earth ground.
