6 Keysight E8257D/67D & E8663D PSG Signal Generators Installation Guide
Getting Started
Configuring the Display
Pressing the decrease contrast hardkey 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.
Press to increase the display contrast.
Pressing the increase contrast hardkey 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.
Press Utility > Display > Brightness.
This allows you to change the display’s brightness.
Brightness can be adjusted using the arrow keys, numeric keypad, or front panel knob. The brightness
value is set to 50 (maximum brightness) at the factory. The minimum brightness value is 1.
Inverse Video
Press Utility > Display > Inverse Video Off On.
This toggles between inverse video mode and normal display mode.
The normal display mode for the signal generator is dark text on a light background. Inverse video
mode is light text on a dark background. Inverse video is a persistent state; it is not affected by a
signal generator preset or power cycle.
Screen Saver
Press Utility > Display > Screen Saver Off On.
This toggles the operating mode of the screen saver.
You can increase the life expectancy of the signal generator’s display light by activating 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.
Press Utility > Display > Screen Saver Mode.
This toggles the screen saver mode between light- only mode and light- and- text mode.
Adjust the screen saver mode to turn the light on, off, or to turn both the light and text on and off.
Setting the mode to light- only mode turns the display light off, leaving the text visible at a low
intensity. If the display remains unchanged for long periods of time, set the mode to light and text to
prevent the text from burning the display. This mode turns the display light and the text off.
Press Utility > Display > Screen Saver Delay.
This adjusts the amount of elapsed time before the screen saver is activated.
The screen saver delay is set to 1 hour at the factory. 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 are persistent states; they are not affected by a signal generator preset or
