Embodiment Construction

[0030] specific implementation plan

[0031] Such as figure 1 As shown, the broadband signal generator according to the present invention is divided into functions, and is mainly composed of four parts: a communication control module, an intermediate frequency processing module, an up-down conversion module, a local oscillator module, and the like. The communication control module is connected to the intermediate frequency processing module and the local The local oscillator module is connected with the intermediate frequency processing module and the up-down conversion module, the intermediate frequency processing module is connected with the up-down conversion module, and the output of the up-down conversion module is used as the output of the present invention. The intermediate frequency processing module completes the modulation of various modes of modulation signals to the center frequency: 255 ~ 285 MHz (any 256 frequency points in the 30 MHz frequency band) and sends it...

Abstract

The invention provides a broadband signal generator. The broadband signal generator is characterized by comprising a communication control module, an intermediate frequency processing module, an up and down frequency conversion module and a local oscillator module. The intermediate frequency processing module modulates various modes of modulating signals into central frequency and sends the signals to the first frequency conversion branch and the second frequency conversion branch, and then the signals are output at two frequency bands of 30-560 MHz and 560-1000 MHz after being frequency-converted twice by the local oscillator module. The broadband signal generator overcomes the problems of poor frequency accuracy, narrow frequency range, low reaction speed, less function and the like in the prior art and meanwhile improves the production efficiency and facilitates batch production.
