摘要
结合虚拟仪器的特点 ,提出并实现了一种虚拟射频频谱仪的方案 ,着重介绍了其中的中频数字化实现方法。该方案可以在不降低频谱分析精度的前提下大幅度降低频谱仪的价格 。
Combined with the features of virtual instrument, the scheme realizing virtual RF spectrum analyzer is presented and realized in this paper, and digital intermediate frequency method is emphasized. This scheme can reduce the price of spectrum analyzer and improve popularization, without decreasing precision of spectrum analyzer.
