摘要：本应用笔记描述了一个基于PC的14位数据采集系统的设计。它需要一个系统的方法，包括所有必要的积木：模拟，数字，硬件和软件。分别讨论每一个步骤，测试系统整合，并详细介绍沿途了解到的陷阱之前。Maxim > App Notes > A/D and D/A CONVERSION/SAMPLING CIRCUITS AMPLIFIER AND COMPARATOR CIRCUITS Keywords: DAQ, data acquisition, windows-based, pc-based, ADC, analog to digital converter, ADCs, Jun 28, 2002 converters, RS232, AVR, resistor divider, resistive divider, signal conditioning, rs-232 APPLICATION NOTE 1138 Practical Data Acquisition using a Windows-based Power Meter Abstract: This application note describes the design of a PC-based, 14-bit data acquisition system. It takes a system approach, includes all the necessary building blocks: analog, digital, hardware, and software. It discusses each step, testing systems separately before integrating them, and detailing pitfalls learned along the way. Many articles have been written about the building blocks in a typical data acq……
