Functional spectrum analyzer

Abstract

The invention discloses a functional spectrum analyzer which includes a computer and a Labview which is embedded to the computer. The computer and the Labview cooperates to generate a virtual front panel, and forms a signal acquisition module, a signal display control module, a signal filtering module, a parameter measurement module and a waveform storage module in combination with related hardware of the computer. The virtual front panel includes a time-based control module front panel, a gain adjusting and translation module front panel, a signal filtering module front panel and a parameter measurement front panel. According to the invention, the functional spectrum analyzer herein realizes signal acquisition and storage, time-domain waveform display and measurement, frequency-domain parameter measurement, signal filtering processing, waveform storage and printing, local signal reading and analyzing, and the like by using PC hardware platform and the Labview virtual instrument platform. The functional spectrum analyzer herein overcomes high cost, large size and poor universality of current spectrum analyzers. Internet connection allows the functional spectrum analyzer to measure and analyze remote signals, which greatly increases the practicality and portability of the spectrum analyzer.

Description

Technical field: [0001] The invention relates to the field of electronic measuring instruments, in particular to a multifunctional spectrum analyzer. Background technique: [0002] With the rapid development of IT technology, the concept of virtual instrument makes modern computer technology, communication technology and measurement technology achieve an unprecedented close combination, and then triggers a great change in the concept of traditional instrument. Virtual instrument technology makes full use of the powerful software and hardware functions of computers. On the basis of general computer hardware, software replaces the functions of special hardware to realize the measurement of complex data. Virtual instruments will gradually replace traditional testing instruments and become the mainstream of measuring instruments. [0003] With the continuous development of information science, the engineering problems that need to be dealt with are becoming more and more complex...

Problems solved by technology

[0003] With the continuous development of information science, the engineering problems that need to be dealt with are becoming more and more complex, and the requirements for spectrum analysis in signal processing are also getting higher and higher. The diversification of analysis methods is simple and easy to operate. Traditional spectrum analyzers are realizing Various complex functions seem to be a bit powerless

The signal processing circuit design of the traditional spectrum analyzer itself is very complicated, and it is difficult to update. When the new calculation method or calculation requirements come out, the traditional instrument cannot be upgraded or the calculation method can be updated, which cannot meet the requirements of scientific researchers.
