FOREWORD
1. SCOPE OF MANUAL
This manual contains information for the installation, operation, and maintenance of the Communications
System Analyzer.
2. PURPOSE AND USE
The Motorola Communications System Analyzer is a portable test instrument, designed specifically for the
service and monitoring of communications equipment. Its functions supersede those of a Service Monitor,
expanding the features and capabilities to the point wherein servicing is achieved with a single instrument,
rather than a host of separate equipment.
The R2001A is the standard Communications System Analyzer. The R2002A Analyzer, which contains the
IEEE-488 Standard interface control bus, is also available. Programming for the R2002A is covered in Secton
22 of this manual.
The Analyzer improves a technician's efficiency and accuracy and reduces servicing time.
The Communications System Analyzer performs the functions of signal generation, signal monitoring, and
the tests normally associated with the devices listed below.
• Spectrum Analyzer
• Duplex Generator
• Modulation Oscilloscope
• Frequency Counter
• AC/DC Digital
Voltmeter
• RF Wattmeter
• General Purpose Oscilloscope
• Multi-Mode Code Synthesizer
• SINAD Meter
• Sweep Generator
The Analyzer meets the shock and vibration requirements of EIA test RS152B, the same specifications met
by Motorola mobile radios. This minimizes failures when the instrument is used in a mobile service van, and
means it is as tough as the radios it services.
The Communications System Analyzer is designed to be serviced quickly and easily, should a breakdown
occur. The majority of the circuitry is on seven modular plug-in circuit boards which have built-in test points
that aid in isolating the problem to a specific board. Simple plug-in replacement gets the instrument back in
