PROBLEM TO BE SOLVED: To provide a mobile wireless machine test system that allows to perform level calibration and correction with high precision in extreme short time.;SOLUTION: The mobile wireless machine test system that simulates multipath fading and performs the calibration and correction of a signal level with high precision consists of a signaling tester (SS) 10, a fading simulator (FD) 50, a digital signal generator (SG (Signal Generator) for AWGN (Additive White Gaussian Noise))60, an RF interface unit 70, a transmitter tester (TX tester) 80, a control PC (Personal Computer) 90 that integrates and controls the entire test system, and a database (DB) 95 that records and accumulates data required for calibration and correction. And this system classifies an analog error factor and a numerical error factor as a system and is set to perform the calibration and the correction of the signal level by reading out values regarding elements with such as aging and temperature variation from the DB 95.;COPYRIGHT: (C)2004,JPO
