Operating Instructions
Operation of the
Model AD122-96 MX Master Analog to Digital Converter
requires the use of five
push button switches located on the front panel. The liquid crystal display is organized for a quick and
intuitive operator interface. The unit features six screen displays.
Push Button Switches
:
ENTER
Introduces and moves the cursor through screen positions that can be edited by the
operator.
CURSOR
Push buttons allow the user to choose a screen and to select the cursor position. The
UP/DOWN
cursor buttons are also utilized when changing digits of a selected entry.
GO
Initiates changes in Clock Source/Frequency selection, Test Tone, and Preset store.
EXIT
Removes the cursor and allows selection of other screens with the
UP/DOWN
buttons.
Pressing
EXIT
again will cause the unit to go to the main screen.
To Scroll Through Screens:
If the screen cursor is present, you need to remove it by pressing
EXIT
. When the screen cursor is not
present, the
UP/DOWN
buttons serve to move from screen to screen.
To Edit Screens:
Press
ENTER
to introduce the screen cursor at the first editable location. Each additional pressing of
ENTER
will move the cursor to the next editable location. The settings at an editable location may be
changed by the use of the
UP/DOWN
buttons.
Holding the
UP
or
DOWN
buttons will automatically advance the settings. This feature is particularly
useful for increasing or decreasing numbers (such as test tone frequency and amplitude or word
length).
Most operations react to a change of settings immediately without having to press
GO
. There are three
settings requiring the use of the
GO
button:
• Starting the test tone generator.
• Storing the user power-up default settings.
• Changing Sample Frequency Source.
