Overview

Product overview

Key product information and technical features.

The PXI-6225 belongs to National Instruments' M Series DAQ family. Its 80-channel analog input capability distinguishes it from lower-channel-count PXI-622x devices, while retaining 16-bit input resolution and a 250 kS/s maximum input sampling rate.

NI documents the PCI/PXI-6225 in the M Series User Manual, including device-specific pin assignments and cabling references. NI-DAQmx 14.1 also explicitly lists the PXI version of the NI 6225 as supported hardware.

Is the PXI-6225 a PXI or USB device?
