Overview

Product overview

Key product information and technical features.

The PCIe-6320 combines analog input, digital I/O and counter/timer functions on a PCI Express board. Its analog inputs support up to 16 single-ended or 8 differential channels, with 16-bit resolution and a maximum sample rate of 250 kS/s. Sampling is not simultaneous.

Selectable analog input ranges are ±0.2 V, ±1 V, ±5 V and ±10 V. The board also provides 24 bidirectional digital channels and four counters/timers, but no analog outputs. It is bus powered and uses a VHDCI front connection.
