概况随着数字信号处理的理论和各领域科研的深入发展,FFT信号分析仪越来越多的受到重视和需要。近十年来,从国外不断引进这类仪器。尤其在近三年来引进得更多了。其品种约有24种,诸如HP5451C、SD345等等。引进总台数约212台,总价格为2240万美元。随着广泛的宣传和普及,这种需要量越来越大。在这种形势下,研制生产高可靠,性能价格比合理的国产FFT信号分析仪势在必行。我厂TD4070 Overview With the digital signal processing theory and in-depth development of various fields of research, FFT signal analyzer more and more attention and needs. In the past ten years, such instruments have been continuously imported from abroad. In particular, the introduction of more in the past three years. About 24 varieties of its species, such as HP5451C, SD345 and so on. The introduction of the total number of about 212 units, the total price of 22.4 million US dollars. With wide publicity and popularity, this need is growing. In this situation, the development and production of high reliability, cost-effective domestic FFT signal analyzer is imperative.
