Description
The product with the part number 194021B-03 is a PC-based Multifunction DAQ, specifically the model USB-6251 manufactured by National Instruments. This device offers versatility in connection types, including screw terminal, BNC, and mass terminal connector variations, providing flexibility for various application needs.
It is equipped with 8 differential or 16 single-ended analog input channels. The sampling rate of this device is impressive, offering 1.25 MS/s for a single channel and 1.00 MS/s when multiple channels are utilized. The input range is quite flexible, with options of ±1 V, ±2 V, ±5 V, ±10 V, ±0.1 V, ±0.2 V, and ±0.5 V, which allows for a wide variety of signal types to be accurately measured.
The working voltage is rated at ±11 V for both signal and common mode, and the input impedance can be switched on or off with a high resistance of 10 GΩ. Before usage, a warm-up time of 30 minutes is required for optimal performance. To ensure the device remains accurate, it is recommended that calibration is performed at least once in 2 years.
In addition to its input capabilities, the device also features 2 analog output channels with an update rate of 2.86 MS/s for one channel, and 2.00 MS/s per channel when both channels are used. This high-speed output capability makes the USB-6251 a comprehensive solution for data acquisition and output tasks.
