It belongs to the category of <strong>PC-based Multifunction DAQ</strong> with the model <strong>USB-6225</strong>. The <strong>USB-6225 M Series DAQ</strong> Screw Term, DAQmx, SignalExpress LE, Chinese is specifically designed and manufactured by <strong>National Instruments</strong>.</p>
<p>This device offers <strong>80 single-ended</strong> or <strong>40 differential channels</strong> for analog input, supporting a wide range of applications. It features a <strong>16-bit ADC resolution</strong> and can achieve a <strong>maximum sample rate of 250 kS/s</strong> whether operating on single or multiple channels. To ensure precise timing, it maintains a <strong>timing accuracy</strong> of <strong>50 ppm</strong> of the sample rate.</p>
<p>National Instruments recommends calibrating the device <strong>at least once a year</strong> to maintain accuracy and reliability. The input ranges provided by this model include <strong>±0.2V, ±1V, ±5V, ±10V</strong>, with a <strong>maximum working voltage</strong> of <strong>±11V</strong> for analog inputs. The input FIFO size is <strong>4,095 samples</strong>, ensuring ample buffer space for data acquisition tasks. Moreover, it features <strong>overvoltage protection</strong> for all analog input channels and sense channels,
