Figure 2–1: TLA 704 Color Portable Mainframe front panel
The portable mainframe features a 10.4-inch diagonal, flat-panel LCD active-ma-
trix Thin-Film-Transistor (TFT) color display.
The front panel of the portable mainframe includes a QWERTY keyboard, a
hexadecimal numeric keypad, and five front panel knobs. The keypads are active
simultaneously with the standard external keyboard.
QWERTY Keypad.
The QWERTY keypad is useful for file naming and other
operations where a complete alphabetic character set is needed.
Hexadecimal Numeric Keypad.
The hexadecimal numeric keypad is useful for
numeric entry of data.
Front Panel Knobs.
The front panel knobs include a large multi-function knob and
four smaller positioning/scale knobs. The multi-function knob is used primarily
for incrementing and decrementing values in selected menu boxes. The position-
ing and scale knobs (Vertical Position, Horizontal Position, Vertical Scale, and
Horizontal Scale) provide necessary control of DSO applications, as well as the
scrolling of logic analyzer displays.
The glidepoint device, vertically mounted on the front panel, can be used instead
of the external mouse when limited bench space is available. The glidepoint
device and the standard external mouse are active simultaneously.
