<p>PURPOSE:To accurately automate the adjustment maximizing the degree of modulation with simple configuration. CONSTITUTION:An adjustment jig B emits the semi-microwave at all times and receives AM modulation wave returned from a mobile station discrimination circuit A, transmitting the result of the measured degree of modulation through a connection terminal 7 of the mobile station discrimination circuit A to a control section 3. The control section 3 stores the reverse voltage value V1 nearest to the reverse voltage Vtyp providing the maximum degree of modulation in a storage part 2. In an operation mode, the communication is performed by AM modulating the received wave receiving the semi-microwave sent from the ground station in the individual discrimination number stored in the storage part 2. In this case, the maximum degree of modulation is automatically obtained by reading the stored inverse voltage value V1 out from the storage part 2 and applying it from a variable voltage generator 4 to the modulation diode VD of a modulator 5.</p> |
