Abstract

The invention provides a 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; wherein the modulated wave configuration information comprises modulated wave configuration queues and corresponding time intervals; a queue module used for transiting the modulated wave configuration queues to modulated wave control word queues and then for storage, and taking each queue element in the corresponding modulated wave control word queues according to the time intervals; a modulation module used for generating multiple groups of regulate control parameters according to the carrier wave configuration information and each queue element in the carrier wave control word queue according to an enable signal; 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, 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.

Description

technical field [0001] The invention relates to the technical field of test and measurement, in particular to a signal generator with segment modulation function. 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. The signal generator has powerful signal generation capabilities, for example: it can generate digital and analog modulation signals; it can generate basic and commonly used function waveforms, such as sine wave, square wave, triangle wave, sawtooth wave and pulse wave; it can generate continuously changing frequency Sweep frequency signal; can generate pulse train of various waveform functions; can generate arbitrary waveform output and so on. [0003] Modulation technology can convert high-frequency signals that are not suitable for long-distance transmission into signals...
