SCPI Command Descriptions
Error Queue
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 25 messages. Each time the queue is
read an error message is reported, 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 most recent 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?
This command responds with the most recent error message in the error
queue.
:SYSTem:ERRor:NEXT?
This command responds with the oldest error message in the error queue
and removes it from the error queue.
