A list of assemblies can be found at the beginning of the electrical parts list. The
assemblies are listed in numerical order. When the complete component number
of a part is known, this list will identify the assembly in which the part is
located.
Column Descriptions
The component circuit number appears on the diagrams and circuit board
illustrations, located in the diagrams section. Assembly numbers are also marked
on each diagram and circuit board illustration, in the Diagram section and on the
mechanical exploded views, in the mechanical parts list. The component number
is obtained by adding the assembly number prefix to the circuit number.

Subassembly Number
The electrical parts list is arranged by assemblies in numerical sequence (A1,
with its subassemblies and parts, precedes A2, with its subassemblies and parts).
Mechanical subparts to the circuit boards are listed in the electrical parts list.
These mechanical subparts are listed with their associated electrical part (for
example, fuse holder follows fuse).
Chassis-mounted parts and cable assemblies have no assembly number prefix
and are located at the end of the electrical parts list.
Indicates part number to be used when ordering replacement part from
Tektronix.
Column three (3) indicates the serial or assembly number at which the part was
first used. Column four (4) indicates the serial or assembly number at which the
part was removed. No serial or assembly number entered indicates part is good
for all serial numbers.
An item name is separated from the description by a colon (:). Because of space
limitations, an item name may sometimes appear as incomplete. Use the U.S.
Federal Catalog handbook H6-1 for further item name identification.
