Chapter 6 — Assembly Removal and
Replacement, MS202xC
6-1 Introduction
This chapter describes the removal and replacement procedures for the various assemblies. Illustrations
(drawings or photographs) in this manual may differ slightly from the instrument that you are servicing, but
the basic removal and replacement functions will remain as specified. The illustrations are meant to provide
assistance with identifying parts and their locations.
6-2 Electrostatic Discharge Prevention
An ESD safe work area and proper ESD handling procedures that conform to ANSI/ESD S20.20-1999 or
ANSI/ESD S20.20-2007 is mandatory to avoid ESD damage when handling subassemblies or components
found in the MS2026C, MS2027C or MS2028C VNA Master.
6-3 Real Time Clock (RTC) Battery
6-4 Replaceable Parts, Assemblies, and Accessories
To ensure that the correct options are provided on the replacement assembly when ordering a Main PCB
Assembly, all options that are installed on your instrument must be declared on the order. The installed
options are listed on a label on the top of the MS202xC and can also be viewed in the System/Status display.
For a list of replaceable parts, refer to Table 1-7, “Replaceable Parts and Assemblies” on page 1-8.
Warning
All electronic devices, components, and instruments can be damaged by electrostatic discharge. It is
important to take preventative measures to protect the instrument and its internal subassemblies
from electrostatic discharge.
Note
The Real Time Clock (RTC) battery is not field replaceable. The instrument must be returned to the
factory for service.
