PCI-Bus Mastering Data Transfer
The PCI-1721 supports PCI-Bus mastering DMA for high-speed data
transfer and gap-free analog output. By setting aside a block of
memory in the PC, the PCI-1721 performs bus-mastering data transfers
without CPU intervention, setting the CPU free to perform other more
urgent tasks such as data analysis and graphic manipulation. The
function allows users to run all I/O functions simultaneously at full
speed without losing data.
Auto-calibration Function
The PCI-1721 provides an auto-calibration function by using a
calibration utility. The built-in calibration circuitry of the PCI-1721
corrects gain and offset errors in analog output channels thereby
eliminating the need for external equipment and user adjustments.
Waveform Analog Output
The PCI-1721 provides four analog output channels. Both of them can
perform continuous waveform output. The analog output can be up to
10MS/s for each analog output channel. Or you can load a cyclic
waveform into an on-board FIFO, which will continuously output the
cyclic waveform. The on-board FIFO of the PCI-1721 can store 2 to
1024 samples of the waveform.
Keeping the Output Settings and Values after system reset
Users can independently set the four outputs to different ranges:
0~+5V, 0~+10V, ±5V, ±10V, 0~20mA or 4~20mA, and all the ranges are
software selectable. When the system is hot reset (power not shut
down), the PCI-1721 can either retain the last analog output settings
and values, or return to its default configuration, depending on jumper
setting. This practical function eliminates danger caused by mis-
operation during unexpected system reset.
On-board FIFO Memory
The PCI-1721 provides an on-board FIFO (First In First Out) memory
buffer, storing up to 1K samples for D/A conversion.
