PURPOSE: To easily confirm a transmission reception wave without any revising of a satellite communication earth station and without disturbing other communication.
CONSTITUTION: When a transmission wave is sent from an earth station 1, after the transmission wave from a primary radiator 3 is received by a horn section 5 and a voltage of the signal is measured by a control circuit section 6 and the frequency of the signal is converted and the converted signal is emitted as a reception signal from the horn section 5. Thus, the device acts like a function similarly equal to that of a satellite. Consequently, since the confirmation test is conducted without emission of a radio wave toward a satellite, the effect of the transmission wave onto an external device is avoided and the extract of the transmission signal on the way of a transmission section is not required.
