86 Digitizer Command Reference
STATus:PRESet command affects only the enable register by setting all enable
register bits to 0. It does not affect either the "status byte" or the "standard event
status". PRESet does not clear any of the event registers.
STATus:QUEStionable:CONDition? returns a decimal-weighted number
representing the bits set in the Questionable Data condition register.
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.
STATus:QUEStionable:ENABle <unmask> enables (unmasks) bits in the
Questionable Data/Signal Register's enable register to be reported to the summary bit
(setting Status Byte Register bit 3 true). The event register bits are not reported in
the Status Bytes Register unless specifically enabled.
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 (bit 3) in the Status Byte.
