ERROR MESSAGES
Error Messages
In general, whenever the EMS receives an invalid SCPI
command, it automatically generates an error. Errors are stored
in a special error queue and may be retrieved from this buffer
one at a time. Errors are retrieved in first-in-first-out (FIFO)
order. The first error returned is the first error that was stored.
When you have read all errors from the queue, the generator
responds with the message:
0,"No error"
If more than 16 errors have occurred, the last error stored in
the queue is replaced with:
-350,“Queue overflow"
No additional errors are stored until errors are removed from
the queue as described in the following paragraphs.
The error queue is cleared when power has been shut off or
after a *CLS command has been executed. The *RST
command does not clear the error queue. Use the following
command to read the error queue:
SYSTem:ERRor?
All errors have the following format (the error string may
contain up to 80 characters):
<Error Number>, <Error String>
Where:
<Error Number> is a numeric value. This may be
positive or negative
<Error String>
is a descriptive error message,
enclosed in double quotes.
A complete listing of the errors that can be generated by the
EMS is shown in
Table B-1.
