  • Htbasic Development Version
    HTBasic Development Version Written by Administrator Wednesday, 18 February 2009 02:45 - TransEra HTBasic, compatible with Hewlett-Packard's 9000 Series 200/300 Rocky Mountain BASIC, runs on PCs in DOS or Windows. HTBasic is a powerful scientific /engineering language that combines the ease-of-use of BASIC, the math capabilities of FORTRAN and the structured-programming of Pascal and C. When combined with IEEE-488 or data acquisition plug-in cards, HTBasic turns your PC into a full-featured instrument controller. HTBasic provides the Rocky Mountain BASIC integrated program development environment including a syntax-sensitive, full screen editor and interactive execution and debugging statements. HTBasic's LIF transfer utilities allow you to effortlessly port your current HP BASIC data and program files between HP Series 200/300 workstations and PCs (not supported under Windows NT, Windows 2000, or Windows XP). LIF utilities copy programs and data files stored in BDAT, ASCII and HP-UX format between LIF format floppy diskettes and DOS disks. For considerations and instructions on how to port your HP BASIC/9000 programs to HTBasic for Windows, click here: HTBasic Porting Guide.pdf . Once transferred, programs can be run with little or no change avoiding time consuming and costly program rewrites. And the CONFIGURE statement customizes HTBasic to match an HP workstation environment. You get all of the capabilities needed for complex applications without sacrificing inter-platform compatibility. HTBasic can simultaneously share data files over the network with HP BASIC workstations (using SRM/UX), HP BASIC/UX and HP BASIC DOS (measurement coprocessor II cards using NFS).

  • Capacitance-Voltage Measurements: an Expert System Approach
    Capacitance-Voltage Measurements: an Expert System Approach Thesis submitted by James Austin Walls for the degree of Doctor of Philosophy Edinburgh Microfabrication Facility Department of Electrical Engineering University of Edinburgh United Kingdom Abstract The problems for automating capacitance-voltage (C-V) based process monitoring tests are many and varied. The challenges are: interpreting numerical and graphical data, and secondly, performing tests in a correct sequence whilst applying the appropriate simplifying assumptions in the data analysis. A progressive series of experiments using connectionism, pattern-recognition and knowledge-based techniques were researched, culminating with the development of a fully automatic hybrid system for the control of the Hewlett-Packard HP4061 semiconductor test system. This thesis also includes a substantial review of, and guide to, the theory and practice of the high-frequency, low-frequency and pulsed C-V measurements, conductance-voltage and capacitance-time measurements. Several novel software packages have been written (CV-ASSIST, CV- EXPLORE), including a rule-based expert system (CV-EXPERT) for the control and opportunistic sequencing of measurements and analyses. The research concludes that the new approaches offer the full power and sensitivity of C-V measurements to the operator without the burden of careful procedure, interpretation of the data, and validation of the algorithms used. Acknowledgements This thesis is the result of a Cooperative Award in Science and Engineering (CASE) with Hewlett Packard (UK) Ltd.. The support from the U.K. Science and Engineering Research Council (grant No. GR/F 30499) is also gratefully acknowledged. I would like to express my thanks to my supervisor, Dr. A.J.

  • 1 Instrumentation and Control by Notebook PC
    Instrumentation and control by notebook PC - Invitation to HT(HP) – BASIC- Tominaga, Masaki Researcher Advanced Technology Research Group, National Research Institute for Earth Science and Disaster Prevention Abstract Instrumentation and control systems by use of computer are becoming popular. Most of them that we can use in daily experiments are offered in the form of pre-fixed systems. The pre-fixed systems are designed to remove complexity in the setup of the instrumentation and control systems. It is true that the hardware is well combined with the software in those systems, but it is difficult or impossible for us to modify them for our own. Use. On the other hand the published software that have flexibility in use are so well designed that researcher cannot see what is going on in the systems or the programs. In the present paper HT-BASIC is introduced for the use of instrumentation and control by use of notebook PC. The HP-BASIC was a well-acknowledged software to control measurement systems by PC. Researchers could manipulate them for their own use. Since discontinuance of the PC specified for the use of the HP-BASIC the software became unpopular. But new version of the HP-BASIC that name was changed to “HT-BASIC for WINDOWS” is designed to work well in WINDOWS environment. We can make personal systems for instrument and control by the “HP-BASIC for WINDOWS” without much difficulty. Keywords; Notebook PC, BASIC, Field instrumentation, User oriented instrumentation system 1. Foreword These days computers have been widespread and owned privately as multipurpose terminals for information retrieval through internet, e-mail exchange and creating documents.
