STATus :OPERation:ENABle?

•Bit 8 is the only bit used in the condition register (by the System Instrument), therefore, it is the only bit which needs to be unmasked in the event register. Specifying the "bit weight" for the event unmasks the bit. The bit weight is 256 and can be specified in decimal, hexadecimal (# H), Octal (# Q) or binary (# B).

•When the summary bit is sent, it sets bit 7 in the Status Byte register.

Example Unmasking bit 8 in the Event Register
	STAT:OPER:ENAB 256	unmask bit 8
:OPERation:ENABle?
	STATus:OPER:ENABle? returns which bits in the event register (standard
	operation status group) are unmasked.
Comments	• Bit 8 in the condition register is used by the system instrument
	(Command Module) to indicate when an interrupt set up by the
	DIAG:INTerrupt commands has been acknowledged.
	• Bit 8 in the event register generally is the only bit which will be unmasked.
	If this bit is unmasked when STAT:OPER:ENAB? is sent, 256 is
	returned.
	• Reading the event register mask does not change the mask setting
	(STAT:OPER:ENAB < event> ).
	• Related Commands: STAT:OPER:ENABle
Example Reading the Event Register Mask
	STAT:OPER:ENAB?	query register mask
	enter statement
:OPERation[:EVENt]?
	STATus:OPER:EVENt? returns which bits in the event register (standard
	operation status group) are set. The event register indicates when there has
	been a positive transition in the condition register.
Comments	• Bit 8 in the condition register is used by the system instrument
	(Command Module) to indicate when an interrupt set up by the
	DIAG:INTerrupt commands has been acknowledged.

• Bit 8 in the event register generally is the only bit which is used. If this bit is set when STAT:OPER:EVEN? is sent, 256 is returned.

• Reading the event register clears the contents of the register. If the event

register is to be used to generate a service request (SRQ), you should clear the register before enabling the SRQ (*SRE). This prevents an SRQ from occurring due to a previous event.
