Locating a Part or Assembly on a Schematic
The full reference designation assigned to a part or assembly is the key to physically locating that part
or assembly.
NOTE
: Full reference designations contain the assembly hierarchical coding. When the end item is
divided into units (cabinets), the first coding is a unit number (1, 2, 3, etc.). When the end item is
divided into assemblies, the first coding is an assembly number (A1, A2, A3, etc.). If a unit or an
assembly is divided into sub-assemblies, assembly coding that identifies assembly relationship (1A1,
A2A1, A2A1A1, etc.) is added.
1.
Refer to the family trees in
Section 4.2, “Parts Lists” on page 4.2.1
.
2.
Follow the family tree branches to the block that contains the desired reference designation, while
noting the Nautel nomenclatures and names of all higher assemblies in the path. Example:
A8
NAA61B RF Module Assy 1 -> A8A1 NAPA31C Power Amplifier PWB
.
NOTE
: The drawings in the
Mechanical Drawings
section depict the assembly detail of the transmitter
and its modules and assemblies
3.
Refer to
Section 4.5, “Mechanical Drawings” on page 4.5.1
. Use the Nautel
nomenclature and name of each family tree block in the path, starting at the highest assembly –
this is normally Figure
MD-1
– to determine the figure number(s) for that assembly. Example:
NAPA31C Power Amplifier PWB
is shown on
MD-17
.
4.
Refer to the referenced figure (e.g.,
MD-17
Section 4.5, “Mechanical Drawings” on page 4.5.1
to
locate the desired part or assembly.
