发明名称 SYSTEM FOR CONFIRMING TRANSMISSION PERFORMANCE
摘要 PROBLEM TO BE SOLVED: To provide a system that confirms transmission performance of a radio unit or a radio controller or the like for its normal communication or control. SOLUTION: The transmission performance confirming system is provided with an attenuator 2 that can attenuate a reception level in a plurality of steps by an operation section 6, a display section 7 that displays a reference level to monitor the reception level and the reception level to be monitored in a comparison enable way, and a variable resistor(VR) with a switch(SW) 10 that fine-adjusts the level displayed on the display section 7. A proper reception level is set to the attenuator 2 through a test transmission from a unit to be monitored in advance, the output of the attenuator 2 is stored in a memory 5 and displayed on the display section 7 after fine-adjusting the level so that the display section 7 displays the reference level and also the monitored reception level in a comparison enable way.
