SYSTem:ERRor?
Reads and clears one error from the error queue.
Parameter Typical Return
(none) <+0,"No error">
Reads and clears the first error in error queue: SYST:ERR?
l
The front-panel ERR annunciator turns on when one or more errors are currently stored in the
error queue. Error retrieval is first-in-first-out (FIFO), and errors are cleared as you read them.
When you have read all errors from the error queue, the ERR annunciator turns off.
l
If more have accumulated than the queue can hold, the last error stored in the queue (the most
recent error) is replaced with -350,"Error 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
The error queue is cleared by the *CLS and when power is cycled. It is not cleared by a *RST.
l
Errors have the following format (the error string may contain up to 80 characters).
<
error code >,< error string > For a list of error codes and message strings, see SCPI Error
Messages .
