ENGINEERS and scientists now can access the high-quality measurement capabilities of National Instruments data acquisition (DAQ) hardware as easily as plugging a USB cable into a computer.

Five new USB DAQ products - the first in a series of devices scheduled for release during 2004 - deliver easy connectivity, portability and decreased system setup time.

The new family of high-quality USB devices includes:

* DAQPad-6016 - 16-channel, 16-bit AI module, 200kS/s max, two AO, 32 DIO, two CTR/timers.

* DAQPad-6015 - 16-channel, 16-bit AI module, 200kS/s max, two AO, eight DIO, two CTR/timers.

* USB-9215 - four-channel, 16-bit simultaneous sampling AI module, ±10 V, 20kS/s max.

* USB-9211 - four-channel, 24-bit thermocouple input, ±80 mV, 14S/s max.

* SCXI-1600 - up to 352 channels, 16-bit AI module, 200kS/s max.

The NI DAQPad-6015 and NI DAQPad-6016 add 16-bit accuracy to the NI USB multifunction DAQ product line and increase the maximum sampling rate of the product line to 200kS/s for a single channel.

Both devices offer built-in screw terminal connectivity, eliminating the need to purchase a cable and terminal block.

The NI USB-9211 and 9215 deliver integrated signal conditioning and are the first in a series of single-function USB DAQ devices.

The USB-9211 is a four-channel, 24-bit, highly accurate thermocouple measurement device that includes built-in screw terminal connectivity.

The USB-9215 is a four-channel, 16-bit, simultaneous sampling analogue input device that accurately measures multiple signals with minimal phase delay.

Both devices come with free ready-to-run data-logging software so users can begin gathering data immediately.

The SCXI-1600 DAQ module delivers plug-and-play USB connectivity to 40 measurement modules within the NI SCXI signal conditioning platform.

Because the DAQ device is integrated into the SCXI-1600 module, the user needs only to connect to a computer with a single cable.

The small size and easy connectivity of all NI USB DAQ devices make them ideal for operations such as in-vehicle data logging and environmental monitoring.

They also are useful in academic settings where students and researchers must share hardware and labs.

In addition, by combining the new SCXI-1600 data acquisition module and new SCXI Sensors plug-and-play hardware, engineers can build a complete plug-and-play measurement system, saving valuable time and resources previously spent installing hardware and manually entering configuration information from data sheets.

A recent NI survey of data acquisition customers and prospects found that system setup can comprise 18 percent of overall measurement cost.
