Questionable Data Summary (bit 3)
This bit is set when an enabled Questionable-Data event has occurred. It is cleared by
reading the Questionable Data Event Register or by clearing relevant bits in the Questionable
Data Enable Register.
Message Available Summary (bit 4)
This bit indicates that the Output Queue contains response data. It is cleared by reading all
data from the output queue or, the output queue being flushed by a Query Error or, by the
*CLS command. This works for IEEE only - the bit is always 0 for RS-232.
This bit is particularly useful for synchronising data transfers from the instrument. The
application programme can poll the bit to detect when a measurement is complete and data is
available. Alternatively, for IEEE, the corresponding enable bit in the Service Request
Enable Register can be set so that a Service Request (SRQ) interrupt will occur.
Standard Event Summary (bit 5)
This bit Indicates that an enabled Standard Event has occurred. It is cleared either by reading
the Standard Event Status Register, by clearing relevant bits in the Standard Event Enable
Register, or by the *CLS common command.
Request for Service/Master Summary Status (bit 6)
The meaning of this bit depends on how the Status Byte Register is read. This works for
IEEE only - the bit is always 0 for RS-232.
RQS
This bit forms part of the IEEE-488.1 Service Request function and is valid only during
Serial Poll. It indicates that the instrument is requesting service. It is set when an enabled bit
in the Status Byte Register becomes set and cleared by a Serial Poll. Assuming no 'new
reason for service' occurs, the bit will be set for one Serial Poll and clear for subsequent
Polls. RQS is also cleared if the reason for service disappears, for instance when a status
register is read.
MSS
When the Status Byte Register is read with *STB? this bit indicates that an enabled bit in the
Status Byte Summary Register is set. The bit is cleared when all summary-messages are
clear.
Operation Summary Message (bit 7)
This bit is set when an enabled Operation event has occurred. It is cleared by reading the
Operation Event Register or by clearing the relevant bits in the Operation Enable Register.
