High-Speed M Series DAQ Model Guide Overview and Applications National Instruments high-speed M Series devices are optimized for superior accuracy at fast sampling rates. They have an onboard NI-PGIA 2 amplifier designed for fast settling time at high scanning rates, ensuring 16-bit accuracy even when measuring all channels at maximum speeds. They are ideal for applications including test, control, and sensor measurements. For test, the analog inputs and 10 MHz digital lines can be used for applications including electronics test and component characterization. With the fast sampling rates, they can accurately acquire dynamic signals. High- speed M Series devices also have quadrature encoder inputs, protected digital lines, and digital debounce filters for control applications. With four waveform analog outputs and two 80 MHz counter/timers, M Series devices can execute multiple control loops simultaneously and can control pulse-width modulated signals. For sensor measurements, M Series devices are compatible with SCC and SCXI signal conditioning, and can measure IEEE 1451.4 smart sensors. Synchronize the operations of multiple devices using the RTSI bus or PXI trigger bus. Recommended Accessories Signal conditioning is required for sensor measurements or voltage inputs greater than 10 V. National Instruments SCXI is a versatile, high-performance signal conditioning platform, optimized for high-channel-count applications. NI SCC provides portable, flexible signal conditioning options on a per-channel basis. For applications not requiring signal conditioning, refer to the table below for recommended cabling and accessories.
