National Instruments USB-6351 Multifunction I/O Device

The USB-6351 (Part Number: 781440-01) is a Multifunction I/O Device from National Instruments. This device has 8 differential and 16 single-ended analog input channels. The analog to digital resolution is about 16 bits. Each single-ended channel has 1.25 MS/s sample rate and 1.00 MS/s for multiple channels. This device has a timing resolution of 10 ns. The timing precision is 50 ppm. The NI USB-6351 uses input DC coupling. The AI channels have the highest working voltage of ±11 V. This voltage range is for both single and common modes.

The National Instruments USB-6351 Multifunction I/O Device has one analog trigger, which can perform in different analog modes, including the edge mode of operation for trigger requirements. It also includes analog window triggering. The analog trigger has the bandwidth -3 db. The NI USB-6351 X Series device also consists of 2 analog outputs with 16 bit DAC resolution. One channel has the highest update rate of 2.86 MS/s, while two channels have an update rate of 2.00 MS/s. The USB 6351 NI is structured with the NI‑STC3 timing and synchronization technology. These advanced techniques enable the module to provide enhanced timing functionality. This Multifunction I/O Device offers independent digital and analog timing engines. Furthermore, it is used for trigger-able measurement tasks.

The NI USB-6351 X Series DAQ is viable for a variety of applications. This Multifunction I/O Device comes with the classification application to manipulate basic data, which enables the user to control the procedures that involve the automation of the testing process. The module is equipped with configuration utility software and a NI-DAQmx driver. This software enables the module to simplify measurements and configuration. The NI USB-6351 has 24 digital lines that can be used as inputs/outputs. This Multifunction I/O Device is also featured with 32-bit counters, which are used for encoders and frequency, as well as PWM. It has a recommended warm-up time of 15 minutes, and should be calibrated at least once in 2 years.

The NI device weighs 2 oz, and measures 10.4 x 6.8 x 1.4 in. in physical dimensions. It has a recommended operating temperature range of 0 to 45 °C, a storage temperature range of -40 to 70 ºC.
