B-30 BOP-1K 031912B.115 STATus:OPERation[:EVENt] QUERY STAT:OPER?Syntax: Short Form: STAT:OPER[:EVEN]? Long Form: STATus:OPERation[:EVENt]?Return Value: Description: Indicates changes in conditions monitored by Operational Event Register (see Table B-3).Returns the value of the Operation Event register. The Operation Event register is a read-only registerwhich holds (latches) all events that occur. Reading the Operation Event register clears it. (See exam-ple, Figure B-10.)B.116 STATus:PRESet COMMAND STAT:PRESSyntax: Short Form: STAT:PRES Long Form: STATus:PRESetDescription: Disables reporting of all status events. This command sets the Operation Enabled Register (TableB-3) to 8193 and the Questionable Register to 255. (See example, Figure B-10.)B.117 STATus:QUEStionable[:EVENt]? QUERY STAT:QUES?Syntax: Short Form: STAT:QUES[EVEN]? Long Form: STATus:QUEStionable[EVENT]?Return Value: actual register valueDescription: Indicates the latched condition of the Questionable Event register. Returns the value of theQuestionable Event register (see Table B-4). The Questionable Event register is a read-only registerwhich holds (latches) all events. Only bits 13 and 12 are latched in the Status Questionable Event reg-ister. Bits 0 and 1 of the Status Questionable Condition Register are not latched in the power supply.Reading the Questionable Event register clears it. (See example, Figure B-10.)B.118 STATus:QUEStionable:CONDition? QUERY STAT:QUES:COND?Syntax: Short Form: STAT:QUES:COND? Long Form: STATus:QUEStionable:CONDition?Return Value: actual register valueDescription: Returns the value of the Questionable Condition Register (see Table B-4). The QuestionableCondition Register contains unlatched real-time information about questionable conditions of thepower supply. Bit set to 1 = condition (active, true); bit reset to 0 = condition (inactive, false). Bits 1 or0 may be both be set, indicating the power supply is settling after a voltage change. (See example,Figure B-10.)B.119 STATus:QUEStionable:ENABle COMMAND STAT:QUES:ENABSyntax: Short Form: STAT:QUES:ENAB Long Form: STATus:QUESionable:ENABle Description: Programs Questionable Condition Enable Register (see Table B-4).The Questionable ConditionEnable Register determines which conditions are allowed to set the Questionable Condition Register;it is a mask for enabling specific bits in the Questionable Event register that can cause the question-able summary bit (bit 3) of the Status Byte register to be set. The questionable summary bit is the log-ical OR of all the enabled bits in the Questionable Event register. Bit set to 1 = function enabled(active, true); bit reset to 0 = function disabled (inactive, false) . (See example, Figure B-10.)TABLE B-4.
