Abstract: A broadcasting signal generator for normal operation detection of a DMB(Digital Multimedia Broadcasting) receiver and a normal operation detecting system are provided to reappear the same broadcasting provision environment as real situation by simultaneously transmitting broadcasting signals of a frequency band corresponding to plural broadcasting stations by all-in-one system according to a programmed state. A multiplexer(110) receives signals from plural encoders and multiplexes the received signals. A modulator(120) modulates the signal inputted from the multiplexer. A splitter(130) divides the signal, inputted from the modulator, into plural frequency components and outputs the divided frequency components. RF(Radio Frequency) up-converters(151~156) convert the frequency component, divided and inputted by the splitter, into a signal of a specified frequency band and transmit the converted signal. The splitter further comprises a tuner for tuning a signal so as to be suitable for characteristics for each frequency components.
