B) DISPlay:TEXT[:DATA] <a>
Message Types: String
‘aa…a’ or “aa…a”
Indefinite Block
#0aa…a
Definite Block
#XYaa…a
where: Y = number of characters in message (up to 12)
X = number of digits that make up Y (1 or 2)
The display message can be up to 12 characters (ASCII) long. 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 message 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.
C) DISPlay:TEXT:STATe <b>
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 instru-
ment 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.
