Overview

Product overview

Key product information and technical features.

The USB-6003 combines analog acquisition, analog output, digital I/O and a counter/timer in a USB-connected device. Its analog inputs provide 16-bit resolution with up to 8 single-ended or 4 differential channels. Sampling is not simultaneous.

Two 16-bit analog output channels complement the input functions, while 13 bidirectional digital channels provide digital signal access. USB bus power eliminates the need for a separate device power supply.

The supplied NI part-number records distinguish the enclosed USB-6003, 782608-01, from the USB-6003 OEM board-only kit, 782609-01. Confirm the required mechanical variant when specifying a system.

16-bit analog acquisition with a maximum sample rate of 100 kS/s.
Selectable input wiring configurations support up to 8 single-ended or 4 differential channels.
Two 16-bit analog output channels with a maximum listed update rate of 5 kS/s.
13 bidirectional digital channels and one counter/timer.
USB 2.0 connectivity with bus-powered operation.
2047-sample analog input FIFO buffer.
