USB data acquisition

National Instruments has released what it claims are the first 80-channel USB data acquisition devices, BNC USB M series devices and a USB-9237 C series module.

The complete USB data acquisition offering now spans more than 45 devices with single-channel sampling rates of up to 1.25 MS/s, analog generation of up to 2.86 MHz and correlated digital I/O of more than 1 MHz for low-, mid- and high-channel-count applications.

The 80-channel USB M series devices are high-channel-count USB multifunction data acquisition devices; the BNC USB M series provides direct BNC connectivity; and the USB C series offers less expensive and more portable hardware.

With the plug-and-play connectivity of USB, engineers and scientists have an easy-to-use, portable solution for their measurement, monitoring and control applications.

Using the M series devices, engineers can collect more data with less equipment because the devices provide high-channel-count application solutions in a single device. The USB-6225 and USB-6255 offer 80 channels for analog inputs and up to 1.25 MS/s (750 kS/s aggregate) sampling rates per channel.

The devices feature NI signal streaming and provide up to 48 digital input/output lines and two counter/timers.

USB-6221, USB-6229, USB-6251 and USB-6259 BNC USB M series devices include the standard M series features along with direct BNC connectivity that provides up to 16 differential analog inputs, four analog outputs, eight digital I/O BNC connectors and up to 60 screw terminals.

The BNC USB M series features BNC connectivity directly on the USB device, eliminating the need for an extra cabled accessory to house BNC connections.

M series technologies, including the STC 2 system controller, PGIA 2 amplifier and MCal calibration, provide more performance, more accuracy and more I/O than other data acquisition devices. The devices combine M series performance with high-speed USB ease of use to handle a wide range of applications including automated test, process control and sensor measurements.

All M series devices support signal streaming technology, making it possible to acquire and generate multiple analog and digital I/O signals simultaneously.
