Model 6482 Dual-Channel Picoammeter / Voltage Source Reference Manual Section 16: SCPI Command Reference
Query :KEY? Query last pressed key.
Description This command is used to simulate front-panel key presses. For example, to select
the channel 1 measurement function (MSR1), you can send the following
command to simulate pressing the MSR1 key:
:syst:key 15
The parameter listing above provides the key-press code in numeric order.
The queue for the :KEY? query command can only hold one key-press. When
:KEY? is sent over the bus, and the Model 6482 is addressed to talk, the key-
press code number for the last key pressed (either physically or with :KEY) is sent
to the computer.
The key-press code number for the last key pressed (either physically or with
:key) is sent to the computer.

RS-232 interface
NOTE The following commands are intended for use over the RS-232 interface, but they can
also be used over the GPIB.
LOCal
:SYSTem:LOCal Take Model 6482 out of remote
Description Normally, during RS-232 communications, front-panel keys are operational.
However, the user may wish to lock out front-panel keys during RS-232
communications. See RWLock.
This action command is used to remove the Model 6482 from the remote state
and enables the operation of front-panel keys in a manner similar to the GPIB GTL
command.
REMote
:SYSTem:REMote Place the Model 6482 in remote
Description This action command is used to place the Model 6482 in the remote state in a
manner similar to the GPIB REN command. In remote, the front-panel keys will be
locked out if local lockout is asserted. See “RWLock,” page Section 16-55.
RWLock
:SYSTem:RWLock Disable or enable front-panel keys
Description This command is used to enable local lockout in a manner similar to the GPIB
LLO command (see Section 12). When enabled, the front-panel keys except
OUTPUT OFF are locked out (not operational) when the instrument is in remote.
