The National Instruments USB-6289 is a robust Multifunction I/O Device designed for seamless connectivity to PCs and portable systems via a Hi-Speed USB port. This device is equipped with advanced measurement capabilities, offering a warm-up time of 30 minutes and an optimal performance calibration interval of two years. It supports a maximum working voltage of ±11 V relative to AI GND, encompassing both the signal and common mode voltage, and operates under a power supply requirement of 11 to 30 VDC. The USB-6289 utilizes four USB signal streams accommodating analog inputs, analog outputs, digital inputs, digital outputs, and counter/timer functions. It features two 32-bit general-purpose counters/timers with edge counting, pulse, semi-period, period, and two-edge separation measurement capabilities, supporting internal base clock frequencies of 80 MHz, 20 MHz, and 0.1 MHz, as well as an external base clock frequency of up to 20 MHz.

Users benefit from one analog trigger with 10-bit resolution, featuring Analog Edge Triggering and Analog Window Triggering modes. The device offers 16 differential or 32 single-ended analog input channels, alongside four analog output channels, each with respective resolutions of 18 bits for ADC and 16 bits for DAC. The sampling rate is 625 kS/s for single channels and 500 kS/s for multiple channels. Additionally, all analog input and sense channels are equipped with overvoltage protection, ensuring reliability during operation. Available dimensions include a screw terminal option of 10.5 in. × 6.73 in. × 1.75 in. and a mass termination option of 7.4 in. × 6.73 in. × 1.75 in., with respective weights of 3 lb 5.5 oz and 2 lb 5.5 oz. The USB-6289 is covered by a 2-3 year warranty, and user and maintenance manuals are readily accessible for download.
