Short-form format: :syst:key?
Response message: 1 to 31
Description This command is used to simulate front panel key presses. For example, to select DCV you can send the
following command to simulate pressing the DCV key:
:syst:key 15
The parameter listing provides the key-press code in numeric order. Figure 4-40 also provides the key-
press code.
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 which function is currently select-
ed and 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, on the FREQ function, you can display the trigger level 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 order of NEXT displays for each measurement function is provided in the appendix for Menu Struc-
tures.
