PROBLEM TO BE SOLVED: To measure the reception sensitivity diversity of radio equipment, while suppressing the difference of antenna input levels by keeping continuity in the output waveforms of a signal generator, inputting continuous waveforms to a phasing simulator and providing stable phasing amplitude distribution. SOLUTION: The insertion losses of respective routes to the antenna of radio equipment are found (S1). The maximum insertion loss among these losses is found (S2). The integral parts of correction values of respective attenuators are calculated (S3). An average insertion loss after the correction of attenuators is calculated (S4). The average insertion loss, and the designated input level are subtracted from the transmission level of the signal generator and the average attenuation quantity of attenuators is calculated (S5). The integral part of the average attenuation quantity and the integral parts of correction values of the respective attenuators are added and the respective attenuators are set (S6). The level of the signal generator is set to the level for which the decimal part of the average attenuation quantity as mentioned above is subtracted from the fixed level of the signal generator (S7). |
