Low cost processor-controlled RF field strength measurement system for 850 MHz coverage evaluation

This paper describes an automated 850 MHz field test instrumentation system. The system, based on an Apple II Plus processor, was designed to gather detailed statistical RF coverage information as well as to act as a general-purpose radio coverage test tool. The constraints behind the selection of an APPLE II Plus processor are outlined. Details are also given of the software design approach and experience with the instrumentation in the field.
