The NI PCI-6731 delivers high-performance, reliable, high-speed analog outputs to meet a wide range of application requirements. It provides four analog output channels with up to 1 MS/s per channel, 16-bit resolution, and digital triggering. The board uses the RTSI bus to synchronize with additional data acquisition, motion, and vision products, so you can create custom measurement solutions to test innovative designs. The PCI-6731 is ideal for applications such as stimulus-response tests, including acoustic distortion testing, and simulation, such as three-phase power simulation.

Since your device does not have direct signal connectivity, you need a connector block to act as an interface between your sensors/signals and your device. A connector block provides easy access to the inputs and outputs of your hardware.
You need a cable to transmit signals between your device and your signal connections on your connector block.
You need software to interface with your hardware and to collect, analyze, present, and store your measurements. This board is compatible with a variety of programming languages, including LabVIEW, C/C++, Visual Basic, and .NET. LabVIEW provides the easiest integration with all of your NI hardware and is recommended to maximize your hardware investment.
