Error Messages
In general, whenever the Model 3162B 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 a
0,"No error" message.
If more than 30 errors have occurred, the last error stored in the queue is
replaced with -350, “Queue Overflow”. No additional errors are stored until you
remove errors from the queue. If no errors have occurred when you read the
error queue, the generator responds with 0,"No error".
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?
Errors have the following format (the error string may contain up to 80
characters):
-102,"Syntax error"
A complete listing of the errors that can be detected by the generator is given
below.
-100,"Command error". When the generator cannot detect more specific errors,
this is the generic syntax error used.
-101,"Invalid Character". A syntactic element contains a character, which is
invalid for that type.
-102,"Syntax error". Invalid syntax found in the command string.
-103,"Invalid separator". An invalid separator was found in the command string.
A comma may have been used instead of a colon or a semicolon. In some
cases where the generator cannot detect a specific separator, it may return
error -100 instead of this error.
