Chapter 9 Schematics, Board Layouts, and Parts Lists

9.1

Introduction

This chapter contains the schematics, board
layouts, and parts lists for the XTS 5000 radio.
Use them in conjunction with the theory of
operation and the troubleshooting procedures,
charts, and waveforms to isolate a problem to
the component level. In the schematics, the red
color denotes voltage paths, blue denotes the
receive path, and green denotes the transmit
path.
The following table lists the pages where the
schematics and board layouts for the XTS 5000
