CHAPTER 1. INTRODUCTION
The Validyne Data Acquisition System (VDAS) selects, processes, displays, and records realtime measurement data from a collection of sensors in accordance with user-customized
configuration files.
The measurement system is comprised of three elements - a hardware chassis of electronic
cards, a computer, and controller software. The controller, running under Windows 98, serves as
the user interface with the measurement system.
This user manual primarily covers operation of the software, the Validyne Data Acquisition
System (VDAS) Controller. Simple procedures for installing and connecting the various
components of the system are covered in Chapter 2.
The VDAS Controller's functions include:
• Delivering data from the electronic card chassis to the user during and after test
sequences
•
Configuring individual tests by data channels and data groups
•
Controlling the execution of tests in designated sequences
• Manipulating the raw data from selected channels into a desired form by formula,
unique to each channel
•
Structuring the real-time display of test results as a selected type of presentation
•
Storing test results in files along with test information header for ready reference
General Description of System
Two of the three major components in the measurement system - the chassis and the software
controller - are products of Validyne Engineering Corporation. The third component is a computer
running Windows 98. This is available commercially and is not included with the VDAS system.
