:QUEStionable:ENABle?

STATus:QUEStionable:ENABle? returns a decimal-weighted number representing the bits enabled in the Questionable Data/Signal Register’s enable register signifying which bits will set QUE in the Status Byte.

:QUEStionable[:EVENt]?

STATus:QUEStionable[:EVENt]? returns a decimal-weighted number representing the bits set in the Questionable Data/Signal Register’s event register. This command clears all bits in the event register when executed.
