<P>PROBLEM TO BE SOLVED: To make it possible to perform training for a variety of interference of a microwave radio transmission channel. <P>SOLUTION: In a radio interference training system 1, a microwave radio device (transmitter) 2 transmits a microwave through a communication cable 4 and a microwave radio device (receiver) 3 receives the microwave. The transmitter 2 displays the radio wave intensity of the transmitting microwave, and the receiver 3 displays the radio wave intensity of the receiving microwave. A variable amplifier and attenuator 5 is connected in the middle of the communication cable 4, receives a radio wave intensity or an attenuation amount from an interference training device 6, amplifies or attenuates a microwave received from the transmitter 2 so that the receiver 3 receives a microwave corresponding to the value, and then transmits the microwave to the receiver 3. The interference training device 6 displays the state of a part that will be a factor of the radio interference (for example, antenna direction) on a console in a pseudo manner, makes it possible to manually change the state, determines the radio wave intensity or attenuation amount at the receiving side based on the state, and transmits it to the variable amplifier and attenuator 5. <P>COPYRIGHT: (C)2013,JPO&INPIT |
