Output Queue - Agilent Technologies InfiniiVision 5000 Series Programmer's Manual

Output Queue

The output queue stores the oscilloscope- to- controller responses that are
generated by certain instrument commands and queries. The output queue
generates the Message Available summary bit when the output queue
contains one or more bytes. This summary bit sets the MAV bit (bit 4) in
the Status Byte Register.
When using the Agilent VISA COM library, the output queue may be read
with the FormattedIO488 object's ReadString, ReadNumber, ReadList, or
ReadIEEEBlock methods.
