Description
The USB-6225 is a highly sophisticated data acquisition device manufactured by National Instruments. This model, recognized by its part numbers 779974-01, 779973-02, 779973-04, 779973-01, and 779974-04, stands out due to its exceptional versatility and performance in various applications.
One of the most remarkable features of the USB-6225 is its analog input channels. It offers a total of 80 channels, which can be configured as either 80 single-ended or 40 differential channels, providing users with flexibility in their measurement setups. The device boasts a 16-bit ADC resolution, ensuring high-precision measurements.
When it comes to sampling rates, the USB-6225 does not disappoint. It can achieve a maximum sample rate of 250 kS/s, whether operating on a single channel or multiple channels simultaneously. This capability is complemented by a timing accuracy of 50 ppm of the sample rate, further enhancing the precision of data acquisition tasks.
Users are advised to allow a recommended warm-up time of 30 minutes for the device to stabilize and to perform calibration at least once a year to maintain optimal performance. The USB-6225 supports various input ranges, including ±0.2V, ±1V, ±5V, and ±10V, with a maximum working voltage for analog inputs of ±11V. It also features an input FIFO size of 4,095 samples and provides overvoltage protection for all analog input and sense channels, with an input current limit of ±20 mA maximum in overvoltage conditions.
Additionally, the USB-6225 is equipped with two analog output channels with a 16-bit DAC resolution. It can reach a maximum update rate of 833 kS/s for one channel and 740 kS
