Error Messages
-350,Queue overflow
When the queue overflows, the least recent errors remain in the queue, and the
most recent error is discarded. Reading an error from the head of the queue
removes that error from the queue, and opens a position in the tail of the queue for
a new error, if one is subsequently detected.
When all the errors have been read from the queue, further error queries will
return:
0,No error
The SCPI query
SYSTem:ERRor?
is used to view messages in the SCPI error
queue. The error queue will be cleared when any of the following occur (IEEE
488.2, section 11.4.3.4):
•
upon power up
• upon receipt of a
*CLS
command
•
upon reading the last item from the queue
In the SCPI error queue, the permanent errors are re-reported after the message
0,
No error
is read using the
SYSTem:ERRor?
query and after the
*CLS
command is executed.
