41 Status Reporting
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 Keysight VISA COM library, the output queue may be read with
the FormattedIO488 object's ReadString, ReadNumber, ReadList, or
ReadIEEEBlock methods.
