Error messages
Error number: -310
-310 System error
One of "system errors" defined for the 4294A occurred.
-311 Memory error
An error was detected in the memory of the 4294A.
-330 Self-test failed
The result of the self-test was a failure. Contact your local Agilent Technologies sales
office or service center, or refer to the service manual.
-350 Queue overflow
The queue contains a certain code, instead of the code that caused this error. This code
indicates that an error has occurred due to insufficient space in the queue but it has not been
recorded.
-400 Query error
A comprehensive Query error occurred for which 4294A could not detect further details of
the error. This code simply indicates the occurrence of a Query error that is defined in
IEEE488.2,11.5.1.1.7 and 6.3.
-410 Query INTERRPUTED
Status that causes an "INTERRUPTED" Query error. (Refer to IEEE488.1,6.3.2.3.) This
error occurs, for example, when, after Query, data byte (DAB) or GET is received before
the response has been sent completely.
-420 Query UNTERMINATED
Status that causes an "UNTERMINATED" Query error. (Refer to IEEE488.2,6.3.2.) This
error occurs, for example, when the 4294A is specified as a talker and an incomplete
program message is received.
-430 Query DEADLOCKED
Status that causes a "DEADLOCKED" Query error. (Refer to IEEE488.2,6.3.1.7.) This
error occurs, for example, when both input and output buffers become full and the 4294A
cannot continue processing.
-440 Query UNTERMINATED after indefinite response
In a certain program message, after a Query that requested an ambiguous response was
executed, another Query was received. (Refer to IEEE488.2,6.5.7.5.7.)
