PURPOSE: An oscillator for testing broadcast signals receiving efficiency of a receiving terminal is provided to efficiently repair and replace a control unit. CONSTITUTION: A housing(241) controls an output level of an RF signal according to a control signal transmitted through the first control port. A heat radiation surface(242) on which a concavo-convex is formed is formed as the outer surface of the housing. An RF receiving terminal(244) receives an RF signal from an RF transmitting terminal through a communication cable. An RF output terminal(245) outputs an controlled RF signal to a tested device. The second control port receives a control signal transmitted from the first control port. |
