24-Bit, 6-Channel, 1.25 MS/s/ch PXI Analog Input Module—The PXIe‑4481 is an analog input module for higher bandwidth voltage measurements. The module offers analog and digital filtering for accurate frequency domain measurements. You also can select from four gain settings to configure your input range. For measuring sudden changes, such as high speed blast and pressure events, the PXIe-4481 can sample up to 20 MS/s per channel in time domain mode. The included NI-DAQmx driver simplifies hardware configuration and measurement.
