SYSTem:ERRor[:NEXT]?
Reads and clears one error from the error queue. See SCPI Error Messages for the complete SCPI error
message list.
Parameter Typical Return
(none) -113,"Undefined header"
Read and clear the first error in the error queue:
SYST:ERR?
l
Up to 20 errors can be stored in the instrument's error queue. Each remote interface I/O session
(GPIB, USB, VXI-11, Telnet/Sockets) has its own interface-specific error queue. Errors appear in the
error queue of the I/O session that caused the error. For example, if an error was generated by a com-
mand sent over GPIB, send
SYSTem:ERRor? from GPIB to read the error queue. Errors generated by
instrument hardware are broadcast to all I/O sessions.
l
Error retrieval is first-in-first-out (FIFO), and errors are cleared as you read them. The instrument beeps
each time an error is generated (unless disabled by
SYSTem:BEEPer:STATe OFF ).
l
If more than 20 errors have occurred, the most recent error stored in the queue is replaced with -
350,"Queue overflow". No additional errors are stored until you remove errors from the queue. If no
errors have occurred when you read the error queue, the instrument responds with +0,"No error".
l
Errors have the following format (the error string may contain up to 255 characters).
< error code >,< error string >
Where:
< error code > = a positive or negative integer
<
error string
> = a quoted ASCII string up to 255 characters
