Locating a Part or Assembly on a Mechanical Drawing
1. When a part or assembly is assigned a reference designation (e.g., A2A1 or A2A1R1 ), refer to the
family trees in Section 4.2, “Parts Lists” on page 4.2.1 . Follow the family tree branches to the block
that contains the desired reference designation and Nautel nomenclature (e.g.,
NAPA31C Power
Amplifier PWB ). Note the reference designations and Nautel nomenclatures of all higher
assemblies in the path.
Example:
A8 NAA61B RF Module 1 -> A8A1 NAPA31B Power Amplifier PWB .
2. Refer to Table 4.5.1 on page 4.5.2 . Use the reference designation and Nautel nomenclature to
identify the appropriate mechanical drawing.
Example:
NAPA31C Power Amplifier PWB is shown on schematics MD-13 .
3. If necessary, refer to the referenced figure (e.g., MD-13 ) in the mechanical drawings at the end of
this section and locate the next, lower-level assembly. Then, repeat this procedure until the desired
part or assembly is found.
