SCPI COMMANDS-
ERROR QUEUE
MESSAGES AND
COMMANDS As error messages occur, they are placed in the error queue. Each
message will contain a number, a comma (,) and a brief description of the
error. Negative (-) numbers are used for SCPI defined messages while
positive (+) numbers relate specifically to the instrument.
The error queue can hold up to 10 messages. Each time the queue is
read the oldest message is presented and removed from the queue. If
no errors exist the message “0, No error” will be returned. If the queue is
full the message “-350, Queue Overflow” will occupy the last queue
location. It is an indication that at least one, perhaps more error
message(s) were lost.
There are certain error status bits that will set in the STANDARD EVENT
register. These bits provide general error indications. The error queue
will provide more detailed information about the errors.
:SYSTem:ERRor?
:SYSTem:ERRor:NEXT?
This command places the oldest error message in the output queue and
removes it from the error queue.
