An automated data acquisition system is being developed for the Vacuum Generators HB 501 ultrahigh-resolution dedicated scanning transmission electron microscope. The new analytical capabilities of this class of electron microscope require fresh approaches to computerization of data acquisition and analysis. Available commercial systems have been limited in both the kinds of data that can be acquired concurrently and the algorithms for processing the data. As part of this system, a desktop data acquisition and analysis program, called Desk Top Spectrum Analyzer and X-Ray Database (DTSA), has been developed for the Macintosh II (and higher) class of computers. The data acquisition is accomplished utilizing specially modified commercial plug-in bus cards and control software routines that interface to the control and analytical software of DTSA. A patent, to be held jointly by the NIH and NIST, is pending on this analytical tool. The DTSA is available from the Office of Standard Reference Data (OSRD), National Institute of Standards and Technology, for a modest fee. A copyright has been obtained by the OSRD.

正在为真空开发自动数据采集系统 HB 501超高分辨率专用扫描传输发生器 电子显微镜。 此类的新分析能力 电子显微镜需要新的数据计算机化方法 采集和分析。 可用的商业系统受到限制 在可以同时获取的数据类型和 处理数据的算法。 作为该系统的一部分，桌面 数据采集​​和分析程序，称为桌面频谱分析仪 和 X 射线数据库 (DTSA)，是为 Macintosh II（和 更高）级别的计算机。 数据采集​​完成 利用专门修改的商业插入式总线卡和控制 与控制和分析软件接口的软件例程 DTSA。 NIH 和 NIST 联合持有的一项专利正在申请中 这个分析工具。 DTSA 可从标准办公室获取 参考数据 (OSRD)，美国国家标准技术研究院， 只需支付少量费用。 OSRD 已获得版权。
