Overview

Product overview

Key product information and technical features.

The USB-6356 combines analog acquisition, analog output, digital I/O and counter/timer functions in a USB-connected device. Its eight differential analog inputs support simultaneous sampling at up to 1.25 MS/s per channel, with 16-bit resolution.

Selectable analog input ranges extend from ±1 V to ±10 V. Two 16-bit analog output channels offer ±5 V and ±10 V ranges, while 24 bidirectional digital channels and four 32-bit counters/timers provide additional signal-generation and measurement functions.

  • Eight differential analog inputs with simultaneous sampling and 16-bit resolution.
  • Selectable analog input ranges of ±1 V, ±2 V, ±5 V and ±10 V.
  • Two 16-bit analog outputs with ±5 V and ±10 V output ranges.
