PURPOSE:To apply the operating test of a radio equipment to be measured continuously at an optional temperature during aging by using a computer at the outside of an aging room to manage centralizingly the monitor operation supervising the operation-enable/disable state of the radio equipment to be measured and the access operation starting the said ratio equipment. CONSTITUTION:Radio equipments 10-1-10-n to be measured are loaded to a sub-rack 7, which is put in the aging room and kept at an optional temperature. Then the test personnel uses a personal computer 1 to give a command to a power supply control circuit 3 and a transmission control circuit 4. Thus, a power supply equipment 6 is started by a control signal A and a reference voltage signal D is applied to comparators 11-1-11-n in a current monitor 5. Then the radio equipments 10-1-10-n to be measured starts transmission by a control signal B at the same time and output currents C1-Cn are sent to the comparators 11-1-11-n via switches 9-1-9-n respectively. The comparators 11-1-11-n output discrimination signals E1-En based on the comparison between a reference voltage signal D and output signals C1-Cn and they are sent to the personal computer 1 via an I/O circuit 2. |
