TECHNICAL DOCUMENTATION

NOTE:  The  purpose of this technical documentation section is to provide a guide to the TWTA for 

technician-level servicing. It is intended for use by qualified technical personnel who must 
troubleshoot and repair the TWTA in the field. Such repairs are typically limited to replacement of 
modules or major components. For this reason, documentation pertaining to the highest levels of the 
system and to system control logic is included.
