MARKET SURVEY: DESIGN ARSR4 POWER AMP MODULE TEST STATION

This repair manual (TI 6340.56), dated July 31, 1998, provides depot-level maintenance and repair data for Air Route Surveillance Radar-Model 4 (ARSR-4) units under test (UUTs) on the Power Amplifier Module Test Set (PAMTS). It is divided into four manuals: general and specific repair data, assembly drawings, parts lists, and wire data. The manual emphasizes safety, including precautions for live circuits and electrostatic discharge (ESD) sensitive devices. It outlines general repair information, such as unpacking, packing, examination, and cleaning procedures, and details specific repair data for preamplifier, lookdown driver, and power module CCA assemblies, including tools, materials, disassembly, reassembly, and testing. The document is crucial for the Federal Aviation Administration (FAA) to ensure the proper maintenance and repair of critical radar system components.

The Federal Aviation Administration (FAA) is seeking a contractor to design, develop, fabricate, test, and deliver a replacement ARSR4 Power Amplifier Module Test Station (PAMTS). This new PAMTS will replace an obsolete legacy system to improve the testing and repair capabilities for ARSR4 Power Amplifier Module (PAM) boards. The contractor is responsible for providing all necessary labor, facilities, parts, and technical expertise. The new PAMTS must meet specific mechanical and electrical requirements, including operating within a frequency range of 1215 MHz to 1372 MHz and having a minimum meantime between failure (MTBF) of 10,000 hours. The contractor will deliver a production PAMTS unit, test process, fixture hardware, datasheets, block diagrams, and an engineering report. The work will be performed at the contractor's premises, with final inspection and acceptance by the FAA in Oklahoma City. The contractor must maintain an ISO-9001:2008.A compliant Quality Management System and participate in qualification testing and FAA meetings.

This document outlines detailed assembly and fabrication instructions for a "Power Module Circuit Card Assembly" by Westinghouse Electric Corporation. It covers the precise mounting of components, bonding procedures using conductive adhesive, and specific soldering techniques, emphasizing hardware protrusion requirements and maintaining solder-free areas. The file also provides fabrication guidelines for printed wiring boards, including plating specifications for exposed aluminum and copper circuits, hole location tolerances, and artwork references. It highlights electrostatic discharge (ESD) precautions, continuity checks, and torque specifications for certain components. The document includes various views, sections, and drill patterns, indicating alternate configurations and revisions, underscoring the critical need for precision and adherence to standards in manufacturing this complex electronic assembly.

The TI 6340.49 technical manual details depot-level maintenance for the ARSR-4 Power Amplifier Module (PAM) test set. This diagnostic tool conducts functional testing, fault diagnosis, and repair verification for lookdown drivers, preamplifiers, and PAMs. The system comprises a PAM test console, computer/controller, and PAM test fixture, performing tests like transistor collector current, RF peak pulsed power, and spurious emissions. The manual provides detailed technical descriptions, maintenance procedures, troubleshooting guidelines, safety summaries, and a comprehensive table of contents covering general information, installation, controls, theory of operation, maintenance instructions, circuit diagrams, and parts lists. It also outlines power requirements and environmental characteristics.
