National Instruments is offering its next generation of multifunction data acquisition (DAQ) products based on the newly designed NI-STC 2 system controller chip and NI-PGIA 2 amplifier technology. The new NI M Series multifunction DAQ devices offer breakthroughs in accuracy as well as faster sampling rates, more I/O channels and a broad set of expanded features previously not available in multifunction DAQ devices.

The new M Series devices lower the cost per I/O channel by more than 30%, and also reduce overall system costs by minimising set-up time through advanced development tools included in NI-DAQmx measurement services driver software. These 20 devices address low-cost, high-performance and high-accuracy applications.

"In the 10 years since the introduction of the industry-leading NI E Series multifunction DAQ devices, we have collected feedback from thousands of data acquisition customers. The result is our new M Series product line, offering significant enhancements compared to E Series and other multifunction devices," said Tim Dehne, NI senior vice president of R&D.

"The NI-STC 2 consolidates several discrete chips into a single ASIC for more performance in a smaller space, and NI-PGIA 2 amplifier technology improves accuracy while lowering the price for our customers."

M Series multifunction DAQ devices deliver a set of features that makes them suitable for test, control and sensor measurement applications. The core of each M Series device is the new NI-STC 2 synchronisation and timing controller, which allows up to six operations to execute simultaneously at throughput rates up to five times faster than previous DAQ devices.

M Series also offers calibration at every input range, improving measurement accuracy by up to five times in addition to extending the recommended calibration interval on most M Series devices to two years. The redesigned NI-PGIA 2 family of programmable gain instrumentation amplifiers dramatically reduces settling time to ensure accurate measurements - even at the fastest scanning rates.

M Series DAQ devices offer up to 32 18-bit analog input channels, four 16-bit analog outputs, two 32-bit counter/timers and 48 digital I/O lines. Engineers can use the new devices to hardware-time up to 32 of the digital lines up to 10 MHz. Each M Series device includes the latest version of NI-DAQmx measurement services driver software, which delivers easy configuration and a flexible programming interface for NI LabVIEW, Visual Studio .NET and NI LabWindows/CVI.
