Display Mode (Track/Fast)
Last updated: October 28, 2004
Description
There are two display modes to select from when operating the test set remotely.
-
Display mode fast
-
Display mode track
Fast Mode
When operating remotely, there is often no need for the display to be updated as measurements are made. Using the fast display mode will increase the speed of the test set when it is operated remotely.
Fast mode is designed for remote use only. The test set returns to track mode if you change to manual operation.
-
No screen or menu items are visible (except error messages).
-
Error messages will be displayed in their normal location.
-
"This instrument is being operated remotely" will be displayed at the bottom of the screen.
Example
OUTPUT 714;"DISPLAY:MODE FAST" !Selects fast mode
Track Mode
The track display mode is used to allow users to see what the test set is doing while it is being controlled remotely. Track mode is the default mode of the test set.
-
Any changes made remotely will be updated on the screen if that screen is displayed.
-
The error message window will be displayed as required when an error occurs.
Example
OUTPUT 714;"DISPLAY:MODE TRACK"!Selects track mode
Writing Messages to the Display
The capability to write up to four 30-character lines of text to the front panel display for operator messages is available when the display is in
Fast Mode
. This feature can be used to control the flow of software running on an external controller by pressing softkeys on the test set's front panel.
For example, by displaying a message that prompts the operator to press a front panel softkey and then monitoring that softkey through status register bits, the programmer can design code that starts measurements, stops measurements, or branches to a selected routine or function without the need for access to the external computer's keyboard.
The GPIB commands for writing messages to the display are found in the
DISPlay:OPERator:MESSage
table.
The status bit register GPIB commands and bit definitions for monitoring the test set's sofkeys are found in the
STATus:OPERation:KEYPressed Register Bit Assignments
table.
