Hiding the Screen Display

With the E4982A, you can minimize the measurement time by adjusting the screen display settings used during the measurement.

If no information needs to be displayed on the E4982A's LCD display (for example, when measurement is made through GPIB), you should hide the screen display. When the screen display is turned OFF, no time is required for redrawing the image, and this significantly shortens the measurement time.

For the procedure on how to hide the screen display, refer to Hide the Screen Display.

Optimizing the Display Contents

If it is not possible to hide the screen display, try the following settings:

1. Set the screen display to the list measurement display

If it is not necessary to display measured values in the large size of single point measurement display, set the screen display to the list measurement display. The single point measurement display requires a longer time for redrawing images than does the list measurement display because of the wider area used to display the measurement. Use of the list measurement display therefore reduces the measurement time.

For the procedure used to set the list measurement display, refer to Selecting Single Point Measurement or List Measurement.

2. Minimize the number of parameters shown

If one or more parameters do not need to be shown in the list measurement display, turn OFF the display. Each time measurement runs, the rewrite process occurs for the parameters currently shown on the display; thus, measurement time is accordingly lengthened.

For the procedure of hiding the parameters shown, refer to Selection of Display Parameters in List Measurement Display.

3. Resize the firmware window

If its not necessary to view the windows in full screen, set the firmware window as small as possible. Resizing the firmware window as small as possible improves the drawing time (faster).

For the procedure of resizing the firmware window, refer to Minimize and Maximize.

4. Set :DISPlay:UPDate to OFF (:DISPlay:UPDate OFF)

If the :DISPlay:UPDate is set to OFF (0), the firmware stops periodic drawing to improve cycle time. Alternatively, press System > Misc Setup > Periodic Update to turn off the periodic drawing.

For further details, refer to :DISP:UPD.

• When periodic updates is set to OFF, the image on the display is updated when the last point in the table is measured or a GPIB command (except for query command) is executed.

5. Hide the softkey display

When the softkey is displayed, the firmware updates the information on the labels. As such, if it is not necessary to view, hide the softkey display.

To hide the softkey display, press the Entry Off hardkey or Root Menu button at the upper-right of the screen once or twice.
