Error Messages
In general, whenever the 2074 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.
-104,"Data type error". The parser recognized a data element
different than allowed.
-108,"Parameter not allowed". More parameters were received than
expected for the header.
-109,"Missing parameter". Too few parameters were received for
the command. One or more parameters that were required for the
command were omitted.
