2.3 Menu Bars Overview

The menu bar controls the link between windows

and allows the user to exit the program. It also al-

lows the user to initialize the serial port and load

presaved data conversions from a file. The six prin-

cipal windows are the Start-Up, the Setup Window,

the Power Spectrum Window (also referred to as

the FFT window), the Histogram Window, the

Time Domain Window, and the Calibrate Window.

Specifically, the menu bar has the following control

items:

•Menu

To select, click on option Menu from the menu

bar, or use associated hot keys. The items asso-

ciated with MENU are listed and described be-

low.

Start-Up Window

(F1)

Setup Window

(F2)

Power Spectrum Window (F3)

Histogram Window (F4)

Time Domain Window (F5)

Calibrate Window (F6)

These six menu items allow the user to navigate

between the windows. They are available at all

times via the menu bar or hot keys.

Setup

To select, click on option Setup from the menu

bar. The functions available under Setup are:

COM1 - When selected, COM1 is initial-

ized to 9600 baud, no parity, 8 data bits, and

1 stop bit.

COM2 - When selected, COM2 is initial-

ized to 9600 baud, no parity, 8 data bits, and

1 stop bit.

Load From Disk - Used to load and display

previously saved data conversions from a

file. The file must comply with the CDB-

CAPTURE file save format. The format is:

part number, throughput (or sample rate),

number of conversions, maximum range,

and the data conversions. The user is

prompted to enter the path and file name of

previously saved data. To prevent hardware

conflicts, this option is deactivated while in

the Setup Window.

TESTRS232 - This test mode tests the abili-

ty of the PC to communicate to the evalua-

tion board. It consists of two subtests:

1) test the link between the PC and the RS-

232 interface circuitry; and

2) test the RS-232 link between the PC and

the microcontroller.

HDR7 distinguishes these two subtests. Set

HDR7 to Normal to test the complete com-

munication link.

Or set HDR7 to Loop

Back to test the link between the RS-232

Circuitry and the PC. Then, set the test

switches to 110 and reset the evaluation

board. The LED’s should indicate a binary

six signifying that the hardware is ready to

initiate the test. To complete the test, the

user must initialize the PC. First, use the

SETUP menu to select a communications

port and then select the TESTRS232 option.

From there, user prompts navigate the user

through the test. The PC indicates if the test

passes or fails. Once either test is complete,

the LED’s toggle to indicate that the test

mode is complete.
