Product Description

The PAR4CH is the 4 channel member of a family of 24 bit realtime continuous data acquisition systems with an individual A/D per channel architecture. 1 and 8 channel units are also available.

For the PAR4CH 24 bit A/D, highest resolution occurs at 10-1000 Hz, with maximum sampling rates of 5 kHz sustained. All PAR4CH inputs are differential with amplitude ranges of +/- 10 volts. The on board 2 MB DRAM allows continuous no loss data acquisition even on heavily interrupted and multitasking PCs. The PAR4CH sits outside the PC for improved noise performance and communicates its acquired data using the standard PC parallel port.

A full-featured acquisition and display program is included with the system software, so you can be up and running immediately; controlling acquisition rates and continuously saving acquired data to disk. For developing custom applications, low level functions that control the PAR4CH are supplied as static, DLL or shared libraries and as National Instruments LabVIEW drivers. Full source code is included and the PDF user manual contains circuit diagrams.

The 2 MB DRAM data buffer acts as a back up to make sure data is not lost even if the PC is interrupted for long periods on other tasks. There are no "fall through" times or buffer latencies. As soon as any data is ready from the PAR4CH, the PC is notified so it can get the data. Any additional data that comes in while the PC is getting around to servicing the PAR4CH is simply stored up. With 2 MB of buffering at 10 Hz sampling, you have more than 4 hours of back up, with proportionally shorter times at higher frequencies. These times are more than enough to satisfy typical PC latencies.

The PAR4CH comes with all the accessories you need to start acquiring data. These include software, manual (PDF), 9 VDC power supply, 6' parallel port cable, TRM15E 4 channel terminal board, and desktop enclosure. A PC104 adapter plate can be substituted for the desktop enclosure at no additional charge.
