:SYSTem:ERRor[:NEXT]?
Query
:SYSTem:ERRor[:NEXT]?
Parameters None
Parameter Suffix None
Description Read and clear one error from the instrument’s error queue.
A record of up to 30 command syntax or hardware errors can be stored in
the error queue. Errors are retrieved in first-in-first-out (FIFO) order. The
first error returned is the first error that was stored. Errors are cleared as
you read them.
If more than 30 errors have occurred, the last error stored in the queue
(the most recent error) is replaced with “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”.
The error queue is cleared by the *CLS command, when the power is
cycled, or when the firmware is re-started.
The error queue is not cleared by a reset (*RST) command.
The error messages have the following format (the error string may contain
up to 255 characters):
error number,”Description”, e.g.
-113,”Undefined header”.
