PCI-1747U
Feature Details
Auto-Calibration Function
The PCI-1747U provides an auto-calibration function with an calibration utility. The built-
in calibration circuitry of the PCI-1747U corrects gain and offset errors in analog input,
thereby eliminating the need for external equipment and user adjustments.
On-Board Programmable Timer/Counter
PCI-1747U provides a programmable timer counter for generating a pacer trigger for the
A/D conversion. The timer/counter chip is 82C54, which includes three 16-bit counter
10 MHz clocks. One counter is used as an event counter for counting events coming
from the input channel. The other two are cascaded together to make a 32-bit timer for
pacer trigger time base.
Plug & Play Function
The PCI-1747U is a Plug & Play device, which fully complies with PCI Specification Rev
2.2. During card installation, there is no need to set jumpers or DIP switches. Instead,
all bus-related configurations such as base I/O address and interrupt are automatically
done by the Plug & Play function.
Automatic Channel/Gain/SD/BU Scanning
The PCI-1747U features an automatic channel/gain/SD/BU scanning circuit. This circuit
controls multiplexer switching during sampling in a way that is more efficient than
software implementation. An on-board SRAM stores different gain, SD (Single-Ended/
Differential) and BU (Bipolar/Unipolar) values for each channel. This combination lets
users perform multi-channel high-speed sampling with different gain, SD and BU values
for each channel.
PCI-Bus Mastering Data Transfer
PCI-1747U supports PCI-Bus mastering DMA for high-speed data transfer and gap-free
analog input and analog output. By setting aside a block of memory in the PC, the PCI-
1747U performs bus-mastering data transfers without CPU intervention, setting the CPU
free to perform more urgent tasks such as data analysis and graphics manipulation. The
function makes it possible to run all I/O functions simultaneously at full speed without
losing data.
On-board FIFO Memory
PCI-1747U provides 1K samples on-board FIFO (First In First Out) memory buffer for
AD. This is an important feature for faster data transfer and more predictable performance
under the Windows system.
