How to pick yourf DAQ.

Today their are many choices for DAQ boards and modules. USB and on board. Some of the parameters that we use to choose aren't as black and white as they used to. Embedded Technology has a nice article on how one might approach your DAQ solutions.

Today, you have a wider — and better — choice of interfaces for your DAQ system than ever before. External box systems based on 100Base-T and Gigabit Ethernet (including LXI), USB, GPIB, CAN, RS-232/485, as well as a variety of proprietary interfaces, are available. On the plug-in board side of the coil are interfaces for PCI, PXI, PCI Express, Cardbus and ExpressCard. Even boards for the original IBM PC’s ISA bus are still available. To further complicate matters, hybrid systems like UEI’s popular RACKTangle series offer the advantages of an external box with the flexibility and reconfigurability of a board system.
