Abstract

The invention discloses a signal analysis device which comprises a preselector module, a fundamental wave frequency mixing module, a harmonic frequency mixing module, a local oscillator module, a data acquisition and processing module and a PC (Personal Computer) machine, wherein the preselector module is used for shunting signals of which frequencies are over a preset frequency threshold A according to the frequencies, respectively feeding the signals into the fundamental wave frequency mixing module and the harmonic frequency mixing module to carry out processing and converting the frequencies of the signals into required frequencies; the local oscillator module is used for providing local oscillator signals for the fundamental wave frequency mixing module and the harmonic frequency mixing module; the data acquisition and processing module is used for carrying out data acquisition and processing operation on the received signals; and the PC machine is used for controlling the modules through PXIe (Pci Express-extensions-for-instrumentation) buses. By the technical scheme disclosed by the invention, the problems of single function of a signal analysis instrument and incompatibility of instruments of different manufacturers in the prior art can be solved. The invention also discloses a method for configurating the signal analysis device.

Description

technical field [0001] The invention relates to the technical field of instruments, in particular to a signal analysis device and a configuration method thereof. Background technique [0002] At present, equipment development and production units do not have a unified system architecture at the level of hardware and software information interfaces of the test support system, resulting in a single function of the test system of the equipment, incompatibility of test support equipment from various companies, and difficulty in meeting maintenance support needs; In the automatic test system, a large number of specially designed circuits are used to complete the test support work of the equipment. These test instruments will soon become outdated technically. Because the spare parts cannot be obtained, the support work is becoming more and more difficult, and the maintenance cost is also getting higher and higher. [0003] In response to the above problems, synthetic instruments a...
