Query Syntax

:SYSTem:ERRor?

The :SYSTem:ERRor? query outputs the next error number and text from

the error queue. The instrument has an error queue that is 30 errors deep

and operates on a first- in, first- out basis. Repeatedly sending the

:SYSTem:ERRor? query returns the errors in the order that they occurred

until the queue is empty. Any further queries then return zero until

another error occurs.

Return Format

<error number> ::= an integer error code in NR1 format

<error string> ::= quoted ASCII string containing the error message

Error messages are listed in Chapter 34, “Error Messages,” starting on

page 751.
