Abstract

The invention provides an improved signal generator capable of modulating in a segmentable mode. The signal generator comprises an input module used for receiving carrier wave configuration information and modulated wave configuration information input by a user; a carrier wave DDS module used for generating modulating signals according to modulation of a modulation module or generating carrier wave signals according to the carrier wave configuration information; wherein the modulated wave configuration information comprises modulated wave configuration queues and corresponding time intervals; the modulation module used for storing the modulated wave configuration queues, and taking each queue element in the modulated wave configuration queue according to the time intervals; and the segment modulation can be carried out on the carrier wave DDS module according to the carrier wave configuration information and each queue element. The signal generator can realize the segmented regulation function of variable frequency, phase, and / or waveform of the carrier wave, complexity of the generated modulated signal is high, and the modulated signal is difficultly intercepted and decoded, and is suitable for practical application occasions such as modulation-demodulation experiments.
