Removal and Replacement
Procedures
7-1 INTRODUCTION It is strongly recommended that MS462XX Vector Network Measurement
System repair be performed by qualified technical personnel only. The
MS462XX Vector Network Measurement System modular design, exten
-
sive built-in diagnostics, and automated service tools are designed to sup
-
port fast exchange of functional assembly level repairs.
Most components in the MS462XX Vector Network Measurement System
can be removed and replaced as modules, and are designed to easily slide
in and out of the main cabinet. Each component connects to the system
through the rear panel back plane PCB connectors, and to other compo-
nents through coax or other cables. Always make note of the position and
orientation of any cables removed when disassembling system compo-
nents.
Failed assemblies are not field repairable. Once an assembly is found to
be faulty, it should be returned to an authorized Anritsu Service Center
for exchange.
Always verify the need for a component replacement using the trouble-
shooting guidelines presented in Chapter 6. Repair or replacement in the
field to a level beyond the subassemblies listed in this chapter is not rec
-
ommended.
Refer to Section 1-8 for a listing of spare parts mentioned in this chapter.
Contact your nearest Anritsu Customer Service or Sales Center for price
and availability information.
