Query :ENABle? Query state of display
Short-form format: :disp:enab?
Response message: 1 (on) or 0 (off)
Description This command is used to enable and disable the front panel display circuitry. Disabling the display
circuitry allows the instrument to operate at a higher speed. While disabled, the display will be frozen
with the following message:
FRONT PANEL DISABLED
Press LOCAL to resume.
As reported by the message, all front panel controls (except LOCAL) will be disabled. Normal display
operation can be resumed by using the :ENABle command to enable the display or by pressing the
LOCAL key.
Programming example 10 OUTPUT 716; “:disp:enab off; enab?”
20 ENTER 716; A$
30 PRINT A$
40 END
Line 10 Disables the display, and then queries the state of the display.
Line 20 Addresses the Model 2001 to talk.
Line 30 Displays (on the CRT) the programmed state of the display (0; off).
4.16 :FORMat subsystem
The commands for this subsystem are used to select the data format for transferring instrument readings
over the bus. The BORDer command and DATA command affect readings transferred from the buffer
ONLY. (i.e. SENSE:DATA? or CALC:DATA? will always be sent in ASCII.) These commands are
summarized in Table 4-9.
