LABoratory Workbench™ is a high-performance
GUI data acquisition software package for Concurrent Computer Corporation’s
iHawk Linux-based multiprocessing systems. LABoratory Workbench’s
easy-to-use, point-and-click interface allows users to acquire,
process, display and record analog data without the need for programming.
LABoratory Workbench is an X/Motif-based application that runs
under Concurrent’s RedHawk Linux real-time operating system.
A set of symbolic icons and graphic displays represent data acquisition
devices, file operations, signal processing tasks, and display
options. With LABoratory Workbench visual controls, users can configure
an operational data acquisition and signal processing system on
a screen in minutes.

Data Acquisition Without Programming
Workbench leaves scientists and engineers free to concentrate on
the research experiment at hand by providing a
time-saving, visually-oriented, menu-driven data acquisition
and processing configuration environment. LABoratory Workbench
gives you complete no-programming control over Concurrent’s
powerful iHawk data acquisition multiprocessing systems.
LABoratory Workbench provides a complete data acquisition solution
at your fingertips. You can design an application by creating
virtual instruments as fast as you can sketch a data flow diagram
on the screen. Test and refine it immediately, using simulated
or real data. Start and stop with the click of a mouse. Make
data flow or processing changes in seconds. Adjust parameters
while the application is running. You can even integrate your
own or other vendors’ programs into a virtual instrument.
LABoratory Workbench not only allows non-programmers to set
up and run sophisticated data acquisition applications, it can
also be customized by programmers to suit a particular user environment.
FORTRAN expressions can easily be incorporated into an LABoratory
Workbench application as reusable custom icons.
Data Acquisition Control
LABoratory Workbench offers easy access
to mode setting, measurement parameters, control and synchronization
of data acquisition devices.
Data can be acquired continuously in real-time or in runs of
fixed duration. Multiplexing and demultiplexing of data to and
from component channels is supported. Data flow features include
type conversion and data pattern matching.
LABoratory Workbench provides features to manage
data acquired during an experiment. Management of data files
and headers indicating when and how data was collected and processed.
In addition, user-customized instruments can be saved and recalled
with parameter settings intact so that experiments can be identically
A variety of real-time displays are provided including
digitals meters, oscilloscopes, multiple X-Y plots and 3-D waterfall
Waterfall plots can be zoomed, translated and rotated about all
three axes. Flow diagrams and data displays can be printed for
use in research reports.
Build A Complete Data Acquisition System…As Easy
As 1, 2, 3
1. Create a Virtual Instrument
With a mouse, you can select, position and connect modules to
build a virtual instrument. Each module is a labeled icon with
a specific function such as analog-to-digital conversion, multiplexing
and demultiplexing, signal processing, storing or data display.
Virtual instruments perform the operations they depict. Integrate
optional custom software and sampling parameters as needed.
2. Refine Your Design
Before gathering real data, ensure that your instrument will
perform as intended. Using pre-programmed test signals or previously
acquired data, you can run your instrument and verify its functionality.
3. Put The System To Work
You are ready to gather live data. Replace the test signals
with real inputs and select “Start”. You are now
simultaneously acquiring, analyzing, and recording while displaying
your information. Change settings as you go. Modify, save and
recall instruments in ASCII or binary files. Data directories
and files are automatically created, labeled and time-stamped.
Data is now accessible to your other applications or third-party
programs for post processing. Using LABoratory Workbench, you
spend less time on the tedious tasks
