:SYSTem:PRESet
:STATe? Query state of message mode for specified display
Short-form formats: :disp:text:stat?
:disp:wind2:text:stat?
Response message: 1 (on) or 0 (off)
These commands enable and disable the text message modes. When enabled, a defined message (see pre-
vious command) will be shown on the top or bottom portion of the display. When disabled, the message
will be removed from the display, and the Model 2001 will resume normal operation.
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 LOCAL 716), cancels the message and
disables the text message mode.
10 OUTPUT 716; ":disp:text:stat on; stat?"
20 ENTER 716; A$
30 PRINT A$
40 END
Line 10 Displays a defined user message (see previous command) on the top display, and then queries
