The error queue holds up to 15 error messages. Each time an
error is detected by the 1257, it adds a new error to the error
queue. Each time the SYSTEM:ERROR? query is received, the
oldest (least recent) error message is returned.
The syntax for this command is shown below:
:SYSTem
:ERRor?
The reply to the SYSTEM:ERROR? query uses the format:
<error code> , “<error message>”
where:
<error
code>
This parameter is a numeric
value. This value is “0” if there
are no errors remaining in the
error queue. This value is
negative when an error exists on
the error queue.
<error
message>
This parameter is a string
enclosed in double quotes. The
error message provides some
additional information about the
error.
For example, the reply:
0,”No error”
indicates that no errors remain on the error queue, while the reply:
-102,”Syntax error ; missing @ sign”
indicates that a syntax error was detected in a previous command
to the 1257. The reply:
-350,”Queue
overflow”
is returned to indicate that all 15 places in the queue have been
occupied and that the error queue is full.
