Description
The USB-6225 is a PC-based Multifunction Data Acquisition (DAQ) device with part numbers including 779974-01, 779973-02, 779973-04, 779973-01, and 779974-04. This device offers a wide range of features for various data acquisition needs.
It boasts an impressive 80 analog input channels, which can be configured as either 40 differential channels or 80 single-ended channels. This flexibility allows for a broad array of signal measurements. The 16-bit Analog-to-Digital Converter (ADC) resolution ensures high precision in readings.
For sampling rates, the USB-6225 can achieve a maximum sample rate of 250 kS/s for both single and multiple channel configurations, making it suitable for capturing fast-changing signals. The timing accuracy is maintained at 50 ppm of the sample rate, ensuring precise timing for measurements.
The device requires a recommended warm-up time of 30 minutes and should undergo calibration at least once a year to maintain accuracy. It supports various input ranges, including ±0.2V, ±1V, ±5V, and ±10V, with a maximum working voltage of ±11V for analog inputs.
The Input FIFO size is 4,095 samples, providing a buffer for data before processing. Additionally, the device features overvoltage protection for all analog input and sense channels, with an input current limit of ±20 mA maximum under overvoltage conditions, ensuring the safety of the device and connected sensors.
On the output side, the USB-6225 includes 2 analog output channels with a 16-bit DAC resolution. The maximum update rate is 833 kS/s for one channel and 740 kS/s for both channels, allowing for precise control signals to be generated.
