Preface
Scope
This manual describes the functions and features of the LPA50 and LPA100 linear power amplifiers.
It is intended primarily for use by engineers and technicians involved in the installation, alignment,
operation, and maintenance of the LPA50/LPA100.
Equipment Identification
The LPA50/LPA100 equipment is identified by the Catalog Number on the chassis nameplate. You can
decode the Catalog Number using Tables 2-1 and 2-2 (see Chapter 2).
Production Changes
When engineering and production changes are made to the LPA50/LPA100 equipment, a revision notation
(Sub number) is reflected on the style number, related schematic diagram, and associated parts informa-
tion. A summary of all Sub numbers for the particular release is shown on the following page.
Warranty
Our standard warranty extends for either 18 months after the equipment is in-service or 24 months after
shipment, whichever comes first. For all repaired modules or advance replacements, the standard warranty
is 90 days or the remaining warranty time, whichever is longer. Damage clearly caused by improper appli-
cation, repair, or handling of the equipment will void the warranty.
Equipment Return & Repair Procedure
To return equipment for repair or replacement:
1. Call your PULSAR representative at 1–800–785–7274.
2. Request an RMA number for proper authorization and credit.
3. Carefully pack the equipment you are returning.
Repair work is done most satisfactorily at the factory. When returning any equipment, pack it in
the original shipping containers if possible. Be sure to use anti-static material when packing the
equipment. Any damage due to improperly packed items will be charged to the customer, even
when under warranty.
Pulsar Technologies, Inc. also makes available interchangeable parts to customers who are
equipped to do repair work. When ordering parts (components, modules, etc.), always give the
complete PULSAR style number(s).
