Description
The USB-6251 is a PC-based multifunction DAQ device produced by National Instruments. This device, identified by part number 194929B-04, is designed to support a wide range of applications through its versatile connector options including Screw Terminal, BNC, and Mass Terminal. It is equipped to handle multiple input and output requirements with its 8 differential or 16 single-ended analog input channels and 2 analog output channels.
For high-precision measurements, the USB-6251 offers a dynamic range of input voltages (±1 V, ±2 V, ±5 V, ±10 V, ±0.1 V, ±0.2 V, ±0.5 V) and boasts an impressive input impedance of 10 GΩ (on/off). The device is capable of achieving a maximum sampling rate of 1.25 MS/s for a single channel and 1.00 MS/s for multiple channels, ensuring accurate data acquisition across a variety of scenarios. The analog output channels can update at a rate of 2.86 MS/s for a single channel and 2.00 MS/s for two channels, allowing for efficient and precise control signals or data output.
Before initial use, a warm-up time of 30 minutes is required for the device to operate at its best performance. To maintain its accuracy and reliability, the USB-6251 should undergo calibration at least once every 2 years. This maintenance schedule helps ensure that the device continues to deliver high-quality data acquisition and output services over time.
