Error Messages

Read the Error/Event Queue

You read the error queue with the :SYS- Tem:ERRor? query.

Example:

SEND→ :SYSTem:ERRor?

READ← –100, “Command Error”

The query returns the error number fol- lowed by the error description.

If more than one error occurred, the query will return the error that occurred first. When you read an error, you will also re- move it from the queue. You can read the next error by repeating the query. When you have read all errors, the queue is

empty, and the :SYSTem:ERRor? query will return:

0, “No error”

When errors occur and you do not read these errors, the Error Queue may over- flow. Then the instrument will overwrite the last error in the queue with:

–350, “Queue overflow”

If more errors occur they will be dis- carded.

		Command Errors
Error	Error Description	Description/Explanation/Examples
Number
0	No error
–100	Command error	This is the generic syntax error for devices that can-
		not detect more specific errors. This code indicates
		only that a Command Error defined in IEEE-488.2,
		11.5.1.1.4 has occurred.
–101	Invalid character	A syntactic element contains a character which is in-
		valid for that type; for example, a header containing
		an ampersand, SETUP&. This error might be used
		in place of errors –114, –121, –141, and perhaps
		some others.
–102	Syntax error	An unrecognized command or data type was encoun-
	Syntax error; unrec-	tered; for example, a string was received when the
	ognized data	counter does not accept strings.
–103	Invalid separator	The parser was expecting a separator and encoun-
		tered an illegal character; for example, the semico-
		lon was omitted after a program message unit,
		∗EMC1:CH1:VOLTS5.
–104	Data type error	The parser recognized a data element different than
		one allowed; for example, numeric or string data
		was expected but block data was encountered.
