Queues
The output queue is included to power supplies.
Output Queue
: The programmable power supplies store query responses
in the output queue by succeeding the IEEE 488.2 protocol. If the power
supply receives a new command or query message after a message
terminator, the power supply will clear and reset this queue each time.
The computer must read a query response before it sends the next
command (or query) or it loses response to earlier queries.
Error/Event Q ueues
When an error or event occurs, the output queue stores the message. The
output queue stores and reports the messages on a FIFO (first in first out)
state. The
SYSTem:ERRor?
query reads the next item from the output
queue. If output queue overflows, the error message is –350,
“Queue
overflow”
; the queue can’t store or report succeeding messages till it
is read or cleared.
Error Message
Table 8 lists the SCPI error messages for the programmable power
supplies.
