5 = ZCHK key 21 = LIMIT key
6 = REL key 22 = DIGITS key
7 = OPER key 23 = RATE key
8 = SOURCE up arrow key 24 = Cursor left arrow key
9 = ------- 25 = -------

This command is used to simulate front panel key presses. For example, send the follow-
ing command to simulate pressing the “MATH” key: SYSTem:KEY 3. The queue for the
:SYST:KEY? query command can only hold one key-press and this query cannot be used
to determine keys physically pressed from the front panel.
When :SYST:KEY? is sent and Model 6487 is addressed to talk, the key-press code num-
ber for the last :SYST:KEY command is sent to the computer. The value is -1 if a
:SYST:KEY command has not been sent since the last time the unit was placed in remote.
Note that sending :SYST:KEY 1 will simulate a press of the CONFIG key, not LOCAL.
To place the instrument in the local state, send the GTL command as described in
Section 9.
