利用数字化的信号和微型计算机的信号处理能力,极大地扩展了波形分析仪器的应用领域。宽带信号需要转换速率极高的数字模拟转换器,现有技术可做到8位精度的转换时间低达几个毫微秒。由于对模拟输入信号要进行量化,迫使信号处理算法加上各种限制条件。本文从广泛的应用范围中选出了两种应用情况,它们是半导体器件测试和信号频谱分析。 The use of digital signals and microcomputer signal processing capabilities, has greatly expanded the application of waveform analysis instruments. Broadband signals require very high slew rates of digital-to-analog converters, which can be as low as a few nanoseconds over the existing 8-bit resolution. As the analog input signal to be quantified, forcing signal processing algorithms coupled with a variety of constraints. This article selects two applications from a wide range of applications, which are semiconductor device testing and signal spectrum analysis.
