10.9 System Commands
The system commands control the system level functions of the AC Source.
Subsystem Syntax
SYSTem:
ERRor? Returns the error number and error string
KLOCk Keyboard Lock. Sets the power on REMOTE/LOCAL state.
LOCal Go to local mode
PON Define the power on register number
REMote Go to remote mode
SAVE Saves calibration coefficients if calibration state is on
SYSTem:ERRor?
This query returns the next error number followed by its corresponding error message string
from the remote programming error queue. The queue is a FIFO (first-in, first-out) buffer that
stores errors as they occur. As it is read, each error is removed from the queue. When all
errors have been read, the query returns 0,”No Error”. If more errors are accumulated than
the queue can hold, the last error in the queue is -350,”Queue overflow”.
Query Syntax SYSTem:ERRor?
Parameters None
Returned Parameters <NR1>,<SRD>
Example SYST:ERR?
SYSTem:KLOCk
This command sets or clears the power-on LOCAL or REMOTE state. When set (1), the AC
Source will power up in remote state, locking out all keyboard controls. The local state can
only be entered by sending a bus command. This mode may be used to prevent operator
access to front panel controls under all conditions. Note that changing the state of the KLOC
setting does not change the REMOTE or LOCAL state. This setting only affects the
REMOTE/LOCAL state at power-up.
Command Syntax SYSTem:KLOCk
Parameters 0 | 1
Example SYST:KLOC 1
Query Syntax SYST:KLOC?
Returned Parameters <NR1>
Related Commands SYST:REM SYST:LOC
SYSTem:LOCal
This command sets the interface in Local state, which enables the front panel controls. This
command only applies to the RS232C interface. If IEEE 488 is used, the remote/local state
is determined by the REN line on the IEEE 488 interface.
Command Syntax SYSTem:LOCal
Parameters None
Example SYST:LOC
Related Commands SYST:REM
