Preface
The DAS-4300 Series User’s Guide provides the information needed to
install and use the DAS-4301/8K high-speed analog input board.
The manual is intended for data acquisition system designers, engineers,
technicians, scientists, and other users responsible for setting up and
installing DAS-4301/8K boards. It is assumed that users are familiar with
data acquisition principles, with their computer, and with their particular
application.
The DAS-4300 Series User’s Guide is organized as follows:
●
Chapter 1 provides an overview of the features of the DAS-4301/8K
board, including a description of supported software and accessories.
●
Chapter 2 provides a technical description of the features of the
DAS-4301/8K board.
●
Chapter 3 describes how to unpack, set up, and install a
DAS-4301/8K board.
●
Chapter 4 describes how to use the scope and test program to test the
functions of the DAS-4301/8K board.
●
Chapter 5 provides troubleshooting information.
●
Appendix A lists the specifications for DAS-4301/8K boards.
●
Appendix B describes the Keithley Memory Manager.
●
Appendix C presents bandwidth charts for the supported input ranges.
An index completes this manual.
