PRINT #1, "output 16; :disp:text:stat on; stat?" ' Enable and query message
mode
PRINT #1, "enter 16" ' Get response message from
2002
:DATA?
:DISPlay[:WINDow[1]]:DATA? Read top display
:DISPlay:WINDow2:DATA? Read bottom display
These query commands are used to read what is currently being displayed on the top and bottom
displays. After sending one of these commands and addressing the Model 2002 to talk, the dis-
played data (message or reading) will be sent to the computer.
PRINT #1, "output 16; :disp:data?" ' Query displayed data
PRINT #1, "enter 16" ' Get response message from 2002
:CNDisplay
:DISPlay:CNDisplay Clear (cancel) NEXT display
This action command is used to clear the bottom display of NEXT (or PREV) messages and
cancel the operations associated with them. This command has no effect on any other message
types.
This example assumes that a NEXT operation is currently being displayed.
PRINT #1, "output 16; :cnd" ' Clear NEXT display
:SMESsage <b>
:DISPlay:SMESsage <b> Control status message
<b> = 0 or OFF Disable status messages
= 1 or ON Enable status messages
:SMESsage? Query state of status message mode
This command is used to enable/disable the status message mode. The status message mode is
a diagnostic tool that provides real-time messages that relate to the current operating state of the
instrument. Table 2-4 lists the status messages.
PRINT #1, "output 16; :disp:smes on; smes?" ' Enable and query status message
mode
PRINT #1, "enter 16" ' Get response message from 2002
:ENABle <b>
:DISPlay:ENABle <b> Control display circuitry
<b> = 0 or OFF Disable display circuitry
= 1 or ON Enable display circuitry
:ENABle? Query state of display
