Description
The product with the part number 194929D-03L falls under the category of PC-based Multifunction DAQ and is designated as model USB-6251. Manufactured by National Instruments, this device is versatile in its connector options, offering screw terminal, BNC connectors, and mass terminal connectors to accommodate various application needs.
For input, it supports either 8 differential or 16 single-ended channels, providing flexibility in signal acquisition. The sampling rate is impressive, with up to 1.25 MS/s for single-channel operations and 1.00 MS/s across multiple channels. This device is capable of handling a wide range of input signals, as evident by its input range of ±1 V, ±2 V, ±5 V, ±10 V, ±0.1 V, ±0.2 V, ±0.5 V, with a working voltage of ±11 V (signal and common mode).
The input impedance is notably high at 10 GΩ (on/off), ensuring minimal loading on the signal source. However, users should allow a warm-up time of 30 minutes for optimal performance. To maintain accuracy, the device requires calibration at least once in 2 years. Additionally, it features 2 analog output channels, further enhancing its applicability in various data acquisition tasks.
