Questionable Status Group
These two register groups record signals that indicate abnormal operation. The bits in this register may
indicate problems with acquired data. The group consists of a Condition, PTR/NTR, Event, and Enable
register. The outputs of the Questionable Status group are logically OR-ed into the QUEStionable
summary bit (3) of the Status Byte register. See
