Overview

Product overview

Key product information and technical features.

The PCI-4462 belongs to NI's dynamic signal acquisition family for sound and vibration measurements on PCI-based computers. Its input-only design provides four measurement channels rather than signal-generation outputs.

Each input supports independently selectable differential or pseudodifferential configuration and AC or DC coupling. Analog signals connect through female BNC connectors; the digital trigger uses a male SMB connector.

Simultaneous acquisition on four analog input channels.
24-bit dynamic signal acquisition.
AC/DC coupling with a 3.4 Hz AC-coupling cutoff.
Per-channel IEPE excitation selection: off, 4 mA, or 10 mA.
