Introduction to Measurement
Studio
Measurement Studio is an integrated suite of native tools and class libraries
that are designed for developers using Visual Basic .NET, Visual C#, and
Visual C++ .NET to develop measurement and automation applications.
Measurement Studio dramatically reduces application development time
through object-oriented measurement hardware interfaces, advanced
analysis libraries, scientific user interface controls, measurement data
networking, wizards, interactive code designers, and highly extensible
.NET and Visual C++ classes. You can use Measurement Studio to develop
a complete measurement and automation application that includes data
acquisition, analysis, and presentation functionalities.
Installation Requirements
To install Measurement Studio, your computer must have the following:
•
•
Microsoft Windows 2000/XP operating system
Microsoft .NET Framework 1.1 (required only for the Measurement
Studio .NET class libraries)
•
Standard, Professional, Enterprise Developer, or Enterprise Architect
edition of Microsoft Visual Studio .NET 2003 (required to use the
Measurement Studio integrated tools)
•
•
Intel Pentium class processor, 133 MHz or higher
Video display—800 × 600, 256 colors (16-bit color recommended for
user interface controls)
•
•
•
•
Minimum of 128 MB of RAM (256 MB or higher recommended)
Minimum of 200 MB of free hard disk space

Distribution Requirements
To distribute an application built with Measurement Studio .NET class
libraries, the target computer must have a Windows 2000/XP operating
system and the .NET Framework version 1.1.
To distribute an application built with Measurement Studio Visual C++
class libraries, the target computer must have a Windows 2000/XP
operating system.
Installation Instructions
Complete the following steps to install Measurement Studio. These steps
describe a typical installation. Please review carefully all additional
licensing and warning dialog boxes. Measurement Studio 7.1 includes two
CDs—one with support for Visual Studio .NET 2003 and one with support
for Visual Studio 6.0. This manual documents the Visual Studio .NET 2003
CD. For help with Visual Studio 6.0, refer to the Measurement Studio
Support for Visual Studio 6.0 Readme located on the Measurement Studio
for Visual Studio 6.0 CD.
If you install Measurement Studio 7.1 on a machine that has Measurement
Studio 7.0 installed, the installer will replace Measurement Studio 7.0
functionality, including class libraries. The Measurement Studio 7.0
assemblies will remain in the global assembly cache (GAC); therefore,
applications that reference the Measurement Studio 7.0 version will
continue to use Measurement Studio 7.0 .NET assemblies.
If Measurement Studio 7.0 is on your machine, Measurement Studio 7.1
will install to the Measurement Studio 7.0 directory. To install
Measurement Studio 7.1 to the default directory (Program Files\
NationalInstruments\MeasurementStudioVS2003), you must first
uninstall all Measurement Studio class libraries, including class libraries
installed with National Instruments driver software, such as NI-VISA,
NI-488.2, and NI-DAQmx.
Measurement Studio supports side-by-side installation of version 6.0 and
7.1. You must install Measurement Studio 6.0 and 7.1 to different
directories.

display symbols and descriptions for a specific set of elements of another
object, such as the plots or cursors of a graph. When you associate the
legend control with another object, any changes you make to that object are
automatically reflected in the legend. For example, if you associate the
legend control with the plots of a graph, any changes you make in the plots
collection editor are automatically reflected in the legend.

Measurement Studio Parameter Assistant, on the Measurement Studio
menu, to discover and insert into your code valid parameter values for
methods and various Measurement Studio class libraries, such as
NI-DAQmx, NI-488.2, and NI-VISA.
With the Parameter Assistant, you can select the correct parameter value
for a device or resource, as shown in Figure 4-5, based on your current
system configuration. Click the Insert Selected Item button on the

Calling Instrument Drivers from .NET Languages
To use an IVI or VXIplug&play instrument driver with a C DLL in a
Instrument Driver wizard to create .NET entry points to the C DLL
functions you need to call from your application. Use the Add New Item
wizard to select the .NET Instrument Driver Wizard.
The Measurement Studio .NET Instrument Driver wizard, as shown in
Figure 4-6, generates a .NET wrapper class for calling into IVI,
VXIplug&play, and legacy instrument drivers based on the instrument
driver function panel, header file, and an optional .subfile for IVI drivers.
The wizard can generate both Visual C# and Visual Basic .NET source
code. After completing the wizard, a new instrument driver wrapper class
is added to your project and opened in the source code editor.

channel
1. Physical—a terminal or pin at which you can measure or generate an
analog or digital signal. A single physical channel can include more than
one terminal, as in the case of a differential analog input channel or a digital
port of eight lines. The name used for a counter physical channel is an
exception because that physical channel name is not the name of the
terminal where the counter measures or generates the digital signal.
2. Virtual—a collection of property settings that can include a name, a
physical channel, input terminal connections, the type of measurement or
generation, and scaling information. You can define NI-DAQmx virtual
channels outside a task (global) or inside a task (local). Configuring virtual
channels is optional in Traditional NI-DAQ and earlier versions, but is
integral to every measurement you take in NI-DAQmx. In Traditional
NI-DAQ, you configure virtual channels in MAX. In NI-DAQmx, you can
configure virtual channels in either MAX or in a program, and you can
configure channels as part of a task or separately.
3. Switch—a switch channel represents any connection point on a switch.
It may be made up of one or more signal wires (commonly one, two, or
four), depending on the switch topology. A virtual channel cannot be
created with a switch channel. Switch channels may be used only in the
NI-DAQmx Switch functions and VIs.
