中文摘要：
仪器软件化正逐渐成为仪器开发的主流，本文提出了一种个人仪器系统设计的初步思想。在LabVIEW8．2虚拟仪器开发平台上，采用数据采集设备获取信号，利用计算机对信号和数据处理，实现示波器、逻辑分析仪、频谱分析仪和光谱分析仪等仪器的设计，4种仪器在一个平台上通过软件控制分时工作，仪器功能模块部分共享，完成传统独立仪器的功能。实验证明个人系统运行稳定、易修改、易升级、易二次开发。
英文摘要：
Instrument based on software is becoming the main pattern of instrument development. A preliminary idea of personal system design is introduced. The system is designed of data acquisition device and computer in the LabVIEW8. 2 software Platform. It consists of oscillograph model, logic analyzer, frequency analyzer and spectrum analyzer. These instruments can be used as traditional instruments. But they are integrated in one system. The signal is acquired by exterior data acquisition device. Signal and data processing is implemented by software. Some software are subVIs, they can be recalled by all instruments. The tests indicated that the personal instrument system is steady and easy to modify, upgrade and to use as a subVI. The design idea of the personal instrument system is feasible.
