:ERRor?

SYSTem:ERROR? returns the error messages in the error queue. See Appendix B for a listing of possible error numbers and messages.

Comments • The Agilent E1446A places any generated errors into the error queue. The queue

is first-in, first out. With several errors waiting in the queue, the SYSTem:ERRor? returns the oldest unread error message first.

•The error queue can hold 30 error messages. If the Agilent E1446A generates more than 30 messages that are not read, it replaces the last error message in the queue with error -350,"Too many errors". No additional messages are placed into the queue until SYSTem:ERRor? reads some messages or the *CLS (clear status) command clears the queue.

•When the error queue is empty, SYSTem:ERRor? returns +0,"No error".

•Executable when initiated: Yes

•*RST Condition: unaffected

•Power-On Condition: no errors are in the error queue
