Description
The USB-6251 (BNC) model is a PC-based Multifunction DAQ, identified by the part number 197980C-01L. This device offers flexibility in connectivity with its various connector variations including Screw Terminal, BNC, and Mass Terminal.
For high precision applications, it features a maximum sampling rate of 1.25 MS/s for single-channel operations and 1.00 MS/s for multiple channels. The input range is quite versatile, accommodating ±1 V, ±2 V, ±5 V, ±10 V, ±0.1 V, ±0.2 V, and ±0.5 V, with a working voltage tolerance of ±11 V both for signal and common mode.
The device boasts a high input impedance of 10 GΩ, ensuring minimal interference with the measured signal. A warm-up time of 30 minutes is required for optimal performance. For maintenance, a calibration period of at least once every two years is recommended to ensure accuracy.
In terms of output capabilities, it has two analog output channels. The output update rate is impressive, with 2.86 MS/s for a single channel and 2.00 MS/s per channel when both channels are in use, enabling precise control and data acquisition in demanding applications.
