IEEE-488 Reference

The :KEY command allows you to select the NEXT displays over the bus. Sending :SYS-
Tem: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 al-
ways 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 6517A is addressed to talk, the key-press code number for the last
key pressed (either physically or with :KEY) is sent to the computer.
