PCI-1718HDU/HGU offers the following main features:
PCI-Bus Plug & Play
The PCI-1718 cards use a PCI controller to interface the card to the PCI
bus. The controller fully implements the PCI bus specification Rev 2.2.
All configurations related to the bus, such as base address and interrupt
assignment, are automatically controlled by software. No jumper or
switch is required for user configuration.
Automatic Channel/Gain Scanning
PCI-1718HDU/HGU features an automatic channel/gain scanning circuit.
This circuit, instead of your software, controls multiplexer switching dur-
ing sampling. On-board SRAM stores different gain values for each chan-
nel. This combination lets user perform multi-channel high-speed
sampling (up to 100 kHz) for each channel.
