NI Data Acquisition Software
Platforms

• NI Lab View
• NI Lab Windows
• NI Measurement Studio



Lab View
• NI Lab view is a graphical development environment an open software platform we can
easily add wireless measurements to our systems.
• Lab View is a platform and development environment for a visual programming language
from NI.
• The purpose of such programming is automating the usage of processing and measuring
equipment in any laboratory setup.
• Lab view is commonly used for data acquisition, instrumentation control, and industrial
automation on a variety of platforms including Microsoft Windows, Various versions of
UNIX,LINUX, and MAC OS X .

Overview
• NI offers a complete family of data acquisition so we can easily configure
and platform these devices using NI lab view, a development environment
and graphical programming language ideal for performing data acquisition.
• Lab view graphical system design platforms gives us to power to design
and validate the design through real-world implementation with ease
and the flexibility of its open modular platform architecture.



Features Of NI Lab View
• Faster Programming

• Embedded Monitoring and control systems



Data flow programming
• Lab view follows a dataflow model for
Running Virtual instruments.
• A block Diagram node executes when all its
inputs are available. When a node completes execution,
it supplies data to its output terminals and passes the
output data to the next node in the dataflow path.

Lab Windows Environment
• The Lab Windows Environment makes it easy for us to create and tool applications
that use the Lab Windows Libraries.
• The Environment is a combination editor, compiler and debugger with the
extensive run-time checking.
• A special feature called a function panel makes the task of developing programs
easier. Using function panel we can execute a Lab Window library function and
generate code that calls function.
• Function panel contains online help information for functions and function
parameters.
• We can Built, Execute, test and debug the source code for your application
in the Lab Window Environment.



Types of Lab Windows

• Project Window
Project Window in Lab windows list
All the files that make up a particular
Project of program.



• Source Editor Window
• Split Window
• Tags
• The source Editor Window behaves like
a standard source code editor but adds
many useful features such as the
ability to insert commonly used C
constructs( for loops, case statements
etc) color – coding, split windows, and
tags
Split Windows- offers the ability to view two
Portions of your code Simulataneously
Tags offers -an easy way to mark selected
Lines of code



• Standard Input/Output Window
• The standard Input/Output is used for
Simple input and output.
• This Window can contain Upto

between -5 and 5 volts
public class DAQmx Task1 : Task
{
this.Configure();
}
public virtual void Configure()
{
this.AI Channels.CreateVoltageChanne(“Dev1/
ail”, ”Voltage”, AI Terminal Configuration.
Differential -5,5,AI Voltage Units.Volts);
this.Timing.Configure SampleClock(“”,10000,
SampleClock Active Edge.Rising,
