IMPROVED EPR DATA ACQUISITION SYSTEM USING LABVIEW PLATFORM

我们正在设计一个新的用户友好的数据采集站 基于National Instruments的Labview平台， 高频EPR光谱仪 Labview的优势在于 它的图形用户界面和接口的能力，几乎 通过GPIB（IEEE 488）或串行（RS-232）方式的任何仪器 通讯 与信号接收器通信的子程序 已编写为使用GPIB或串行连接， 除了牛津超导电源的广泛扫描 W波段系统 其他仪器，如EIP微波频率 计数器和牛津cf-1200低温恒温器温度控制器将 添加到完整的系统。

We are designing a new user-friendly data-acquisition station based upon the Labview platform of National Instruments to be used on the high frequency EPR spectrometers. The advantage of Labview are its graphical user interface and the ability to interface to almost any instrument by way of either GPIB (IEEE 488) or serial (RS-232) communications. Subroutines to communicate to the signal receiver have been written to use either GPIB or serial connections, in addition to the Oxford superconducting power supply for the wide sweep W-band system. Other instruments, such as the EIP microwave frequency counter and Oxford cf-1200 cryostat temperature controller will be added to complete the system.
