Operation; Controls, Connectors, And Indicators Description; Liquid Crystal Display; Edit Key - Wavetek 75 Instruction Manual

3.1 INTRODUC'I'ION
This section describes the operation of the Model 75.
Paragraph 3.2 describes the controls and connectors
of the instrument. The following paragraphs describe
how to use the various features and modes of the Model
75.
3.2 CONTROLS, CONNECTORS, AND INDICATORS
The front panel controls are organized into four menu
selection keys, three soft keys, three real time keys, the
Counter key, and the Control knob. To change any instru-
ment setting, the appropriate menu key is pressed
repeatedly until thedesiredsoft key labelappears in the
bottom line of the display (see Appendix B for menu
organization). Pressing the associated soft key will cause
the top line of the display to indicate the setting to be
changed. Rotating the Control knob will change the
setting. When the setting being changed has the
possibility of irreversibly changing a waveform, an
execute label (EXEC) will appear for the F3 soft key and
must be pressed before the change takes place. The
Trigger, Hold, and Return keys control the waveform in
real time and are not directly associated with the Con-
trol knob. The Counter key causes the display to indicate
a waveform count as will be discussed below. The front
panel controls and connectors are shown in figure 3-1
and keyed (bold numbers) to the following descriptions.

row of this display will provide labels for the soft keys
that are located directly below the display. Each time
one of the menu keys is pressed the labels will be
updated to match the menu selection (see Appen-
dix B). The upper row of the display will respond to
the soft keys and control knob by indicating the
setting or parameter value corresponding to the last
soft key that was pressed.

to adjust the intensity of the display to match the
viewing angle of the instrument.

line of the display will change to indicate three dif-
ferent waveform editing options. There are a total
of five different sets of three editing options. Any of
these can be invoked by pressing the soft key [Fl
(21), F2 (1 9), or F3 (1 7)] below the corresponding
label on the display.
