Multifunction USB data acquisition systems can be configured for 16 single-ended or for 8 differential analog input channels through software. A software programmable gain instrumentation amplifier is included to extend the measurement range. Gains of 1, 10, and 100 are provided. Full-scale analog input voltage ranges of 0-10 V, +/-10 V, and +/-5 V are also programmable through software. 

Selected units are also equipped with two analog output channels. They provide voltage outputs at 12-bit resolution with a +/-10 V output range. 

Two rate generators are provided, one for pacing analog input acquisitions, and one for pacing analog outputs. The timebase for the rate signal is derived from an internal crystal oscillator, allowing rates from 0.5 Hz to 100 kHz to be programmed.

Multifunction UDAS systems provide 16 TTL-compatible digital I/O channels, configurable through software as inputs or outputs in groups of 8. All inputs and outputs are protected from damage under power on or power off conditions.

Multifunction UDAS systems also include one 32-bit high-speed counter channel. This counter can perform high-speed event counting on TTL level signals up to 10 MHz. Additionally, the counter can perform direct frequency measurements

Power to the UDAS is provided from the PC through the USB port, so you don’t need to worry about finding an AC power outlet or using a battery. An external power option is available for powering systems with high power requirements (for instance, a system which drives a large number of digital outputs or employs many signal conditioning modules).

UDAS units employ high-speed serial communication with error-checking to transfer data to the PC, providing data rates not possible on traditional serial ports. This method guarantees that all data will be transferred to the PC at the USB data acquisition system's full sampling speed.

OEM Versions of these systems are available to those who wish to incorporate this innovative design into a larger system. These "board-only" versions come without the rugged external case, allowing the circuit board to be rack-mounted or housed in an enclosure of your choice.
