Product Description
The PAR1CH is the 1 channel member of the PARxCH family of 24 bit
realtime continuous data acquisition systems. It offers a low cost
way to begin using 24 bit technology with all the capabilities of the
4 and 8 channel systems.
For the PAR1CH 24 bit A/D, highest resolution occurs at
10-1000 Hz, with maximum sampling rates of 5 kHz sustained. The PAR1CH
analog input is differential with an amplitude range of +/- 10 volts.
The on board 2 Mb DRAM allows continuous no loss data acquisition even
on heavily interrupted and multitasking PCs. The PAR1CH 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 PAR1CH 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 PAR1CH, 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 PAR1CH 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 PAR1CH 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.
