Overview

Product overview

Key product information and technical features.

The PXIe-6368 combines simultaneous voltage acquisition, analog output, digital I/O and counter/timer functions in a PXI Express module. Its 16 differential analog input channels provide 16-bit resolution at a maximum sampling rate of 2 MS/s per channel.

Selectable analog input ranges are ±10 V, ±5 V, ±2 V and ±1 V. Four 16-bit analog outputs provide a ±10 V output range, while the VHDCI front connection provides the module's external signal interface. Consult the NI specifications and drawings when planning signal wiring and system integration.
