Abstract

The invention provides a signal generator capable of flexiblely 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; wherein the modulated wave configuration information comprises modulated wave configuration queues and corresponding time intervals; a queue mapping module used for transiting the modulated wave configuration queues to modulated wave control word queues; a modulation module used for storing the modulated wave control word queues, and taking each queue element in the modulated wave control word queues according to the time intervals, and generating multiple groups of regulate control parameters according to the carrier wave configuration information and each queue element; and a carrier wave DDS module used for generating multi-segment modulating signals according to the multiple groups of regulate control parameters and the carrier wave configuration information. The signal generator can realize the segmented regulation function of variable frequency, phase or amplitude of modulated signals, 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.

Description

technical field [0001] The invention relates to the technical field of test and measurement, in particular to a flexible signal generator capable of segmental modulation. Background technique [0002] A signal generator refers to an instrument that generates electrical signals of required parameters, also known as a signal source, and is widely used in production practice and the field of science and technology.
