NOTE
Optional command words and queries are not included in Table 1-3 . Table 15-2
provides an unabridged list of all display commands.
DISPlay:TEXT:DATA <a>
Define text message
This command defines the text message for display. A message can be as long as 12
characters. A space counts as a character. Excess message characters results in an error.
The characters must be enclosed in either single quotes (‘ ’) or double quotes (“ ”).
DISPlay:TEXT:STATe ON | OFF
Control (on/off) message for display
This command enables and disables the text message mode. When enabled, a defined
message is displayed. When disabled, the message is removed from the display.
A user defined text message remains displayed only as long as the instrument is in remote.
Taking the instrument out of remote (by pressing the LOCAL key or sending GTL)
cancels the message and disables the text message mode.
DISPlay:ENABle ON | OFF
Control display circuitry
This command is used to enable and disable the front panel display circuitry. When
disabled, the instrument operates at a higher speed. While disabled, the display is blanked.
All front panel controls (except LOCAL) are disabled. Normal display operation can be
resumed by using the ENABle command to enable the display or by putting the
Model 2700 into local mode (press LOCAL).
Programming example
The following command sequence displays the text message “TESTING”:
DISP:TEXT:DATA 'TESTING' ' Define text message.
DISP:TEXT:STAT ON ' Enable text message mode.
