NI PXI-6250 is an NI M Series PXI Multifunction I/O Module for mixed-signal measurement and control in PXI-based test systems. NI identifies this specific model as a PXI module with 16 analog inputs at 16-bit resolution, 1.25 MS/s maximum single-channel sampling, 24 DIO, and no analog output channels. The model is distinct from nearby M Series variants such as PXI-6251, PXI-6254, PXI-6255, and PXI-6259, and the official NI product page lists part number 779116-01 for PXI-6250.
For analog acquisition, the PXI-6250 provides 16 single-ended or 8 differential analog input channels. NI specifies a maximum analog input sample rate of 1.25 MS/s for single-channel operation and 1.00 MS/s multi-channel aggregate for the 6250 family grouping. Supported input ranges are ±10 V, ±5 V, ±2 V, ±1 V, ±0.5 V, ±0.2 V, and ±0.1 V, with a maximum working voltage of 11 V channel-to-earth, Measurement Category I.
Digital and timing resources include 24 bidirectional digital I/O lines and two 32-bit counters/timers. NI also states that the PXI-6250 supports analog and digital triggering. For digital timing, the NI 6250 supports DI sample clock rates from 0 to 10 MHz on PXI devices, and DO sample clock rates up to 10 MHz when regenerating from FIFO.
