PURPOSE: A broadcasting receiving performance test system of receiver terminal is provided to perform manipulating a tester and checking the test result integrally in control terminal. CONSTITUTION: A pump unit(210) controls a oscillator according to the control signal. A modulation unit(220) modulates broadcasting signal data transmitted from the pump unit according to a control signal. A conversion unit(230) converts a I/Q signal of the modulated/transmitted digital signal form into RF signal of available frequency according to a control signal. A control unit(240) amplifies and damps the output level of the RF signal.
