Description
The USB-6251 is a PC-based Multifunction Data Acquisition (DAQ) device manufactured by National Instruments. The part number for this model is 198105A-02L. This device is versatile and supports multiple connector variations including Screw Terminal, BNC, and Mass Terminal, making it adaptable for various types of connections and applications.
It features 8 differential or 16 single-ended analog input channels, providing flexibility in handling a variety of sensors and signals. The device is capable of a sampling rate of up to 1.25 MS/s for a single channel and 1.00 MS/s when multiple channels are being used simultaneously. This high sampling rate ensures accurate data collection for fast-moving signals.
The USB-6251 offers a wide input range of ±1 V, ±2 V, ±5 V, ±10 V, ±0.1 V, ±0.2 V, ±0.5 V, allowing it to accommodate various signal amplitudes. It also boasts a working voltage of ±11 V (signal and common mode) and an input impedance of 10 GΩ (on/off), ensuring reliable and precise measurements. The device requires a 30-minute warm-up time for optimal performance and is recommended to be calibrated at least once in 2 years to maintain accuracy.
In addition to its input capabilities, the USB-6251 also features 2 analog output channels, with an output update rate of 2.86 MS/s for 1 channel. This allows for the generation of precise signals or the outputting of data for further processing.
Overall, the USB-6251 is a highly capable and flexible DAQ device that is suitable for a wide range of applications in data acquisition and signal processing.
