STATus

	The STATus subsystem reports the bit values of the Questionable Data/Signal
	Register. It also allows you to unmask the bits you want reported from the Standard
	Event Register and to read the summary bits from the Status Byte Register.
	The Questionable Data/Signal Register group consists of a condition register, and
	event register and an enable register. The commands in the STATus:QUEStionable
	subsystem control and monitor these registers.

Comments	The STATus system contains seven registers, four of which are under IEEE 488.2
	control: the Standard Event Status Register (*ESR?), the Standard Event Enable
	Register (*ESE and *ESE?), the Status Byte Register (*STB?) and the Status Byte
	Enable Register (*SRE and *SRE?). The Operational Status bit (OPR), Request
	Service bit (RQS), Standard Event summary bit (ESB), Message Available bit (MAV)
	and Questionable Data bit (QUE) in the Status Byte Register (bits 7, 6, 5, 4 and 3
	respectively) can be queried with the *STB? command. Use the *ESE? command to
	query the “unmask” value for the Standard Event Status Register (the bits you want
	logically OR'd into the summary bit). Query using decimal weighted bit values.

:PRESet

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.

:QUEStionable:CONDition?

STATus:QUEStionable:CONDition? returns a decimal-weighted number representing the bits set in the Questionable Data condition register.

:QUEStionable:ENABle

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.
