Since the measurement is performed in seconds, each antenna is measured for one line in one second, and sequentially stored in the memory, and simultaneously with the completion of the measurement, the file is recorded as data of all antennas of traveling waves and reflected waves. One measurement requires 98 seconds to measure each of 49 traveling waves and reflected waves, one carrier antenna and 48 sideband antennas. Therefore, the measurement cycle of all antennas is set to every two minutes. The measured data is stored in the ring buffer for 10 times and transferred by a request from the equipment diagnosis personal computer 10.

720 times in 0 times 24 hours. This data can accumulate data for a maximum of three years. The graph display includes a current day display (FIG. 3) capable of displaying VSWR data of each aerial for the past 24 hours, and a period designation display (FIG. 2) in which a display period is set and displayed in advance. The stored data is transferred to the monitoring personal computer in response to a request from the monitoring personal computer 14 (base station personal computer).
