Section 14: SCPI command reference
The :KEY command allows you to select the NEXT displays over the bus. Sending :SYSTem:KEY
16 over the bus is same as a single press of the NEXT key. Sending :SYSTem:KEY 8 is the same
as a single press of the PREV key. The NEXT display that is selected depends on how many times
the NEXT key is pressed using the :KEY command. The instrument can always be returned to the
normal display by pressing the PREV key a similar number of times, or by sending the
:DISPlay:CNDisplay command.
For example, you can display the bar graph by pressing the NEXT key twice as follows:
:syst:key 16; key 16
To return to the normal display, press the PREV key twice as follows:
:syst:key 8; key 8
The queue for the :KEY? query command can only hold one key-press. When :KEY? is sent over the
bus, and the Model 6517B is addressed to talk, the key-press code number for the last key pressed
(either physically or with :KEY) is sent to the computer.
