Model 6220/6221 Reference Manual DISPlay, FORMat, and SYSTem Key-Press Codes 13-3
Return to Section 13 topics
The top display message can be up to 20 characters (ASCII) long, and the
bottom display message can be up to 32 characters. A space is counted as a
character. Excess message characters result in an error. Note that for the
string type, the message must be enclosed by single or double quotes.
An indefinite block message must be the only command in the program mes-
sage or the last command in the program message. If you include a command
after an indefinite block message (on the same line), it will be treated as part
of the message and is displayed instead of executed.
3. When the text message mode is enabled, a defined message is displayed.
When disabled, the message is removed from the display.
GPIB operation – A user-defined message remains displayed only as long as
the instrument is in remote. Taking the instrument out of remote (by pressing
LOCAL or sending the GTL (go to local) command) or cycling power cancels
the message and disables the text message mode.
RS-232 operation – A user-defined message can be cancelled by sending
SYSTem:LOCal, pressing LOCAL, or cycling power.
Ethernet (6221) operation – A user-defined message remains displayed only
as long as the instrument is in remote. Taking the instrument out of remote (by
pressing LOCAL or DISP, or cycling power) cancels the message and dis-
ables the text message mode.
