ESG Family Signal Generators Preparing for Use
Installing the Signal Generator
User’s Guide 1-5
Adjusting the Display Contrast
You can adjust the contrast of the display by pressing the decrease contrast key or
the increase contrast key . These keys are located on the front panel below the
display.
Pressing the decrease contrast key and holding it down causes the display background to
gradually darken in comparison to the text on the display. The minimum contrast setting
is not a completely black display. Some contrast between the background and the text will
still be visible.
Pressing the increase contrast key and holding it down causes the display background to
gradually brighten in comparison to the text on the display. If the background does not
appear to change, it is probably set to the maximum contrast.
Selecting Inverse Video
The normal display mode for the signal generator is dark text on a light background. To
change to inverse video (light text on a dark background), press
Utility > Display and set
Inverse Video Off On to On. Inverse video is a persistent state; it is not affected by an
instrument preset or by a power cycle.
Adjusting the Screen Saver
You can increase the life expectancy of the signal generator’s display light by turning on
the screen saver. Leaving the display lit for long periods of time or turning the display on
and off frequently decreases the life of the bulb. With the screen saver on, the display light
is turned off after a defined period of time with no input to the front panel. The display
light turns on again when any front panel key is pressed or when a remote command is
sent.
The screen saver is set to off at the factory. You can turn it on by pressing
Utility > Display >
Screen Saver Off On. Each time you press Screen Saver Off On the selection toggles between Off
and
On.
You can adjust the screen saver mode to turn the light on and off or to turn both the light
and text on and off. Press
Utility > Display > Screen Saver Mode. You can toggle between Light
Only and Light & Text. Setting the mode to Light Only turns the display light off but leaves the
text visible at a low intensity. To prevent the text from burning the display, if you are
leaving the display unchanged for long periods of time, set the mode to
Light & Text. This
mode turns the display light and the text off.
The screen saver delay is set to 1 hour at the factory. You can view and change the delay by
pressing
Screen Saver Delay in the same menu. The current screen saver delay is displayed in
the softkey label and also in the active entry area. To change the delay, enter a new value
using the numeric keypad and then press
Enter, or rotate the front panel knob. The
acceptable range of delay values is 1 through 12 hours in 1 hour increments.
The screen saver settings do not change when
Preset is pressed, nor when power to the
instrument is cycled.
