:ERRor? SYSTem:ERRor? returns the error numbers and corresponding error

messages in the error queue of a switchbox. See Appendix E for a listing of

switchbox error numbers and messages.

Comments • Error Numbers/Messages in the Error Queue: Each error

generated by a switchbox stores an error number and corresponding

error message in the error queue. Each error message can be up to

255 characters long.

• Clearing the Error Queue: An error number/message is removed

from the queue each time the

SYSTem:ERRor? command is sent.

The errors are cleared first-in, first-out. When the queue is empty,

each following

SYSTem:ERRor? command returns 0, "No error".

To clear all error numbers/messages in the queue, execute the

*CLS

command.

• Maximum Error Numbers/Messages in the Error Queue: The

queue holds a maximum of 30 error numbers/messages for each

switchbox. If the queue overflows, the last error number/message in

the queue is replaced by -350, "Too may errors". The least recent

error numbers/messages remain in the queue and the most recent are

discarded.

Example Reading the Error Queue

SYST:ERR? Query the error queue.
