NI USB-9219

4-Channel, 24-Bit, Universal Analog Input Module

This user guide describes how to use the National Instruments USB-9219
and lists the device specifications.

Introduction

The NI USB-9219 provides a USB interface for four channels of universal
analog input with integrated signal conditioning. The NI USB-9219
consists of two components: an NI 9219 module, and an NI USB-9162
carrier, as shown in Figure 1.
