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 Queues
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.
