SCPI Error Messages
The instrument returns error messages in accord with the SCPI standard.
Up to 20 errors can be stored in each interface-specific error queue (one each for GPIB, USB, VXI-11, and Tel-
l
net/Sockets.) Errors appear in the error queue of the I/O session that caused the error.
The instrument beeps once each time a command syntax or hardware error is generated. The front-panel ERROR
l
annunciator turns on when one or more errors are in the error queue.
A special global error queue holds all power-on and hardware-related errors (for example, over-temperature).
l
Error retrieval is first-in-first-out (FIFO), and errors are cleared as you read them. Once you have read all interface-
l
specific errors, the errors in the global error queue are retrieved. When you have read all errors from the global
error queue, the ERROR annunciator turns off.
If more than 20 errors have occurred, the last error stored in the queue (the most recent error) is replaced with -
l
350,"Error 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 instrument responds with +0,"No error".
The front panel reports errors from all I/O sessions and the global error queue. To read the error queue from the
l
front panel, press the System button, then the Help softkey. Then select "View remote command error queue" in
the Help menu.
Error conditions are also summarized in the Status Byte Register. See
l
The interface-specific error queues are cleared by power cycles and *CLS. The error queue is not cleared by *RST.
