Generally, acquiring data means acquiring data. However, in computer terminology, data acquisition is defined as the process of piecing together data from the real world to produce the data that will be manipulated by the computer system. The data is in the form of waves or signals. These signals are obtained using different instruments and devices. The acquired data can be stored in the computer using the software supplied by the supplier and the control can be done with the use of programming languages such as Basic, Pascal, FORTRAN, C, etc.
Data acquisition systems, as the name suggests, are products or systems that are used to collect data or information from a certain source. Data acquisition systems are distinguished as follows: serial communication, USB, parallel ports, and plug-in cards.
Without going too deep, the different data acquisition dashboards are detailed below.
Signatec PDA1000 – This is the data acquisition product manufactured by Signatec. The PDA100 is a 64-bit data acquisition board that is compatible with PCI device kits. The “Plug and Play” function is standard on all PCI devices. The 500 MHz DC analog bandwidth and digitization rate of up to 1 MHz make it remarkably one of a kind. The bus it uses is a Signatec Auxiliary Bus (SAB). This bus can allow data transfer of 500 MB per second. Multiple PDA1000 boards can be connected to the same PDA1000 DAQ board in the master-slave configuration through an interconnect port. It has six selectable signals ranging from 200 million volts to a maximum of 3.2 volts.
OME-PCI-1002 Series: This data acquisition board is manufactured by Omega. It features a 12-bit 110KHz analog-to-digital converter PCI board. The PCI board provides 32 differential or 16 single-ended inputs along with 16 digital inputs and 16 digital output channels. This series of PCI boards provides a sample rate of 110 KS / s. However, it can vary within the series depending on whether the channels are single or multiple. Unlike many other boards from the company, the omega OME-PCI-1002 comes with a software development kit compatible with Windows 98 / NT / 2000 / XP. This software development kit includes DLL files for high-level programming languages and OCX files for Active X programming.
IOTech DaqBoard-3000 Series: This is an integrated multi-function data acquisition board with four 1 MHz PCI boards. Unlike the OME-PCI-1002 board, this board has 16 differential analog inputs or 8 differential analog inputs with the option to expand them up to 64 differential analog inputs or 32 differential analog inputs. The DaqBoard-3000 series has 24 high-speed digital I / O lines. There are four 32-bit counter input channels with quadrature encoder capability. It supports multiple DMA channels and the USB version of this board is also available in the market.
Advantech PCI-1670 – This is a high performance PCI board with GBIB interface. The PCI-1670 board fully works with IEEE 488.1 and 488.2 standards. It has full functionality with Windows 95/98 / NT / 2000 / XP and MS-DOS operating systems. The “Plug and Play” function automatically assigns the I / O address and provides a powerful and easy-to-use configuration utility. It also has full support for C / C ++, C ++ Builder, Visual Basic, and Labview drivers and libraries.
