EVALUATION BOARD SOFTWARE
The software that controls the EVAL-CONTROL BRD2, and
therefore the evaluation board, has two windows. The window
shown in Figure 3 is the window that appears when the software
is first run. It displays information about samples from the
evaluation board in either Fast Fourier Transform (FFT) mode
(Figure 3) or histogram mode (Figure 4). The main window
also provides access to the Setup Menu window (shown in
Figure 5), where the configuration file for the evaluation board
is loaded.
MAIN WINDOW
The main window (see Figure 3 and Figure 4) allows the user to
read a predetermined number of samples from the evaluation
board and display them in both the time and the frequency
domains. The window is divided into three sections.
The upper third contains the control buttons, the menu bar, and
various status display boxes. The control buttons allow the user
to take samples, reset the part, and quit the program. The menu
bar allows the user to display the setup menu, select the printer
port to control the EVAL-CONTROL BRD2, load and save data,
and get information about the software. The status display
boxes indicate the setup of the evaluation board, number of
samples taken, and other information or error messages that are
generated.
