A Miniaturized Multiple Data Source Analog Circuit for Lunar Exploration Project

Abstract

The invention discloses a miniaturized multi-kind data source simulation circuit for a moon exploration project. The miniaturized multi-kind data source simulation circuit for the moon exploration project comprises a CPCI interface, a CPCI bridge circuit, a data source simulator, a digital to analog converter, a filter, an interface circuit, a clock source and a direct digital frequency synthesizer. The miniaturized multi-kind data source simulation circuit can achieve the simulation function of multi-path and multi-mode signals in the same data source simulator, and miniaturization of the data source simulation circuit is achieved.

Description

technical field [0001] The invention relates to the field of radio technology, in particular to a miniaturized multi-type data source analog circuit for lunar exploration projects. Background technique [0002] The test and measurement of electronic products is nothing more than judging the correctness or satisfaction of the output signal under certain input conditions, and the signal source has become an indispensable device in the test. The signal source required for the measurement and control communication subsystem in the lunar exploration project requires both digital baseband signals and analog modulation signals. According to different stand-alone and test conditions, the signal code rate, encoding method, and modulation method can be flexibly set. Currently, there are no devices that provide such functions independently in the market, and are generally integrated in large-scale, multi-functional test equipment. The most famous is the Cortex test equipment of ARM Com...

Problems solved by technology

Currently, there are no devices that provide such functions independently in the market, and are generally integrated in large-scale, multi-functional test equipment. The most famous is the Cortex test equipment of ARM Company, which can customize test functions according to user requirements. However, due to the High integration, the hardware cost of the device itself is very expensive

For large-scale systems such as the lunar exploration project, there are many single machines, and the test function of Cortex cannot be fully utilized when equipped with such test equipment, and the price is extremely expensive, which will bring huge product development costs to the entire project.
