3.4 ERROR CODES
The ReFlex Power™ system supports the SCPI 1999.0 status reporting data
structures. These structures are comprised of status registers and status register
enable mask pairs. The following sections describe these pairs.
3.4.1 E RROR /E VENT Q UEUE
The programmable DC power supplies maintain an Error/Event Queue as
defined by SCPI. The queue holds up to ten error events. Read it by
issuing the
SYSTem:ERRor? query, which reads in a First In/First Out
(FIFO) manner. The read operation removes the entry from the queue.
