SYSTem:COMMunicate:RLSTate LOCal|REMote|RWLock
SYSTem :COMMunicate:RLSTate?
Configures the remote/local/lockout state of the instrument.
Parameter Typical Return
LOCal|REMote|RWLock LOC, REM, or RWL
Sets the remote/local state to remote: SYST:COMM:RLST REM
– The LOCal parameter (the power-on default), disables the remote interface, the REMote parameter enables
remote control of the instrument, and RWLock enables remote control of the instrument and locks out front-panel
operation.
– The remote/local instrument state can also be set by other interface commands over the GPIB and other I/O
interfaces. If multiple remote interfaces are active, the interface with the most recently changed remote/local state
takes precedence.
– This parameter is not affected by *RST or *RCL .
SYSTem:ERRor[:NEXT]?
Reads and clears one error from the error queue.
Parameter Typical Return
(none)
Reads and clear first error in error queue: SYST:ERR?
– The Err annunciator turns on when any error is in the error queue. Error retrieval is first-in-first-out, and errors are
cleared as you read them. When you have read all errors from the error queue, the Err annunciator turns off.
– If more than 16 errors have occurred, the most recent error is replaced with -350,"Error queue overflow". No
additional errors are stored until you remove errors from the queue. Reading the error queue when it is empty yields
the m0,"No error".
– The error queue is cleared by *CLS and power cycling. It is not cleared by *RST.
– Errors have the following format (the error string may contain up to 255 characters).
