Queues
The output queue is included with this digital storage oscilloscope.
Output Queue: This digital storage oscilloscope store query responses in the
output queue by succeeding the IEEE 488.2 protocol. If the Digital storage
oscilloscope receives a lot of un-read query data simultaneously, the output buffer
of Digital storage oscilloscope will be covered repeatedly; for this moment, the
output buffer will generate errors probably. The computer must read a query
response before it sends the next command (or query) or it loses response to
earlier queries.
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.
