Improvement of Measurement Throughput by Screen Display Settings
How to improve 4287A measurement throughput by screen display settings
How to improve 4287A measurement throughput by screen
display settings
With the 4287A, you can minimize the measurement time by adjusting the screen display
settings used during measurement.
Hiding the Screen Display
If no information needs to be displayed on the 4287A'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 needed for redrawing the image, and this significantly
shortens the measurement time. For the procedure used to hide the screen display, refer to
"Hiding the Screen Display" on page 166.
Optimizing the Settings of 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" on page 157.
(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" on page 162.
(3) Turn off update of the screen display
When the display is in view, turning off update of the screen display reduces the time of
internal workings (therefore the measurement time). When using this method, make sure
that the measured values are updated but all other information, such as the status, is not
updated. For the procedure used to turn off update of the screen display and the restrictions
on this feature's use, refer to "Turning ON/OFF Update the LCD Display View" on
page 167.
