SYSTem

Subsystem Syntax

SYSTem:ERRor?

The SYSTem subsystem returns error numbers and error messages in the error queue of a module and the SCPI compliance year (version).

SYSTem :ERRor? :VERsion?

SYSTem:ERRor? returns the error numbers and corresponding error messages in the error queue. See Appendix C for a listing of the applicable error numbers and messages.

Comments Error Numbers/Messages in the Error Queue: Each error records an error number and corresponding error message in the error queue. Each error message can be up to 255 characters long but typically is much shorter.

Clearing the Error Queue: An error number/message is removed from the queue each time the SYSTem:ERRor? query command is sent. The errors are cleared first-in, first-out. When the queue is empty, each following SYSTem:ERRor? query command returns 0, “No error”. To clear all error numbers/messages in the queue, execute either the *CLS or *RST command.

	Maximum Error Numbers/Messages in the Error Queue: The queue holds a
	maximum of 30 error numbers/messages for each module. If the queue
	overflows, the last error number/message in the queue is replaced by
	-350, “Too many errors”. The least recent error numbers/messages
	remain in the queue and the most recent are discarded.
