Chapter 8 Schematics, Board Overlays, and Parts Lists
This chapter contains the schematics, board overlays, 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.
When schematics are viewed on line or as a PDF file, colors can be
seen that denote power and signal paths. The red color denotes
voltage paths, blue denotes the receive path, and green denotes the
transmit path.
The following tables list the pages where the schematics and board
overlays for the XTS 5000 radio are found.
