9.4.6.5 Questionable Register
This register and the "Operation Register" on page 1110 monitor the overall
instrument condition. They are accessed using :STATus:OPERation and
:STATus:QUEStionable.
This register monitors the instrument’s condition to see if anything questionable has
happened. It detects anything that might cause an error or a bad measurement,
such as a hardware problem, an out-of-calibration situation, or a unusual signal. All
the bits are summary bits from lower-level event registers.
