16-2 DISPlay, FORMat, and SYSTem
DISPlay subsystem
A) DISPlay:ENABle <b>
With front panel circuitry turned off, the instrument operates at a higher speed. While dis-
abled, the display is frozen and all front panel controls (except LOCAL) are disabled. Normal
display operations can be resumed by using :ENABle to enable the display, pressing the LOCAL
key, or cycling power.
B) DISPlay:TEXT[:DA
T
A] <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 char-
acter. 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.
