Data Acquisition (DAQ) Fundamentals Introduction Today, most scientists and engineers are using personal computers with PCI, PXI/CompactPCI, PCMCIA, USB, IEEE1394, ISA, or parallel or serial ports for data acquisition in laboratory research, test and measurement, and industrial automation
be changed Note the changes One may want to label the data-set or resulting printout accordingly for easier identification • Taking data: Besides rates and distance, one may note down how long the measurement was carried out for The orientation of the source was already covered Other materials such as lead behind the source may matter
Introduction to Data Acquisition and Signal Conditioning Chapter 1 discusses signals, sensors, and signal-conditioning techniques and how they relate to data acquisition system fundamen-tals It also covers personal computers and how laptop or notebook computers work with data acquisition systems Analog-to-Digital Conversion
microcontroller-based data-logging unit is used to measure the signals of interest and interface the collected data to a PC through an RS-232 serial interface However, serial data transmission limits the system performance if an advanced control capa-bility is desired In this paper, a computer-based data-acquisition system for monitoring both
data acquisition and control solutions The hardware components of the PC-based data acquisition and control units discussed here consist of: 1 LabMaster*f data acquisition and control system, 2 interface box and analog bus expansion system, and 3 satellite expansion boards The LabMaster is briefly described first, to present the
