8 WaveVision4 Software Basics
Please note: The following sections are a brief tour to highlight all of the basic abilities of the
WaveVision4 software. More specific documentation is also available within the WaveVision4 software,
from the Help menu.
8.1 Basic Features
8.2 Board Settings
Before you can collect samples or drive a DAC, the WaveVision4 software must know what kind of
hardware you’re using. To configure the WaveVision4 software’s interaction with your hardware, open the
Board Settings dialog from the Settings menu.
Select the type of board you have from the Board Type pull-down menu.
The Board Settings window also provides a Test button for testing communication between the PC and
WaveVision4 Data Capture Board. Please see Section 3 for more information about setting up a
WaveVision4 evaluation system.
8.3 Capturing Data for ADCs
To collect a set of samples from the hardware, choose Samples from the Acquire menu. If you do not
have any data capture hardware, you may open a sample dataset by choosing Simulated Samples
from the Acquire menu. You may, of course, also open a file.

Depending upon what type of hardware you’re using, you will see a variety of options on the right-
hand side of the window. For WaveVision4 Data Capture Board, the following settings are available:
•
•
Operates with a variety of data capture boards, including the WaveVision4 Data Capture Board.
Allows inspection of sampled waveforms.
Calculates FFTs and histograms.
Provides a wide variety of data import and export abilities.

Board.
Samples collected during data acquisition (for ADCs): This is the number of samples to be
uploaded to the host PC. In general, 8k samples are adequate for most measurements, while 32k
samples are better suited for precision comparisons.
