BIT 4882 030507 B-5
Description: Sets Operation Enable Register. The Operation Enable Register is a mask for enabling specific bits
in the Operation Event Register which will cause the operation summary bit (bit 7) of the Status Byte
register to be set Bit set to 1 = function enabled (active, true); bit reset to 0 = function disabled (inac-
tive, false). The operation summary bit is the logical OR of all the enabled bits in the Operation Event
register. (See example, Figure B-2.)
B.18 STATus:OPEReration:ENABle? QUERY STAT:OPER:ENAB?
Syntax: Short Form: STAT:OPER:ENAB? Long Form: STATus:OPERation:ENABle?
Return Value: <int_value> 0 to 1313 (1 + 32 + 256 + 1024).
Description: Reads Operation Enable Register (see Table B-2). Returns value of Operation Enable Register bits.
Bit set to 1 = function enabled (active, true); bit reset to 0 = function disabled (inactive, false). (See
example, Figure B-2.)
B.19 STATus:OPERation[:EVENt] QUERY STAT:OPER?
Syntax: Short Form: STAT:OPER[:EVEN]? Long Form: STATus:OPERation[:EVENt]?
Return Value: <int_value> 0 to 1313 (1 + 32 + 256 + 1024).
Description: Indicates changes in conditions monitored by Operational Event Register (see Table B-2).
Returns the value of the Operation Event register. The Operation Event register is a read-only register
which holds (latches) all events that occur. Reading the Operation Event register clears it. (See exam-
ple, Figure B-2.)
B.20 STATus:PRESet COMMAND STAT:PRES
Syntax: Short Form: STAT:PRES Long Form: STATus:PRESet
Description: Disables reporting of all status events. This command sets all bits of the Operation Condition
(Table B-2) and Questionable Condition Registers to 0, preventing all status events from being
reported. (See example, Figure B-2.)
B.21 STATus:QUEStionable[:EVENt]? QUERY STAT:QUES?
Syntax: Short Form: STAT:QUES[EVEN]? Long Form: STATus:QUEStionable[EVENT]?
Return Value: <int_value> actual register value
Description: Indicates questionable events that occurred since previous STAT:QUES? query. Returns the
value of the Questionable Event register (see Table B-3). The Questionable Event register is a
read-only register which holds (latches) all events. Reading the Questionable Event register clears it.
(See example, Figure B-2.)
B.22 STATus:QUEStionable:CONDition? QUERY STAT:QUES:COND?
Syntax: Short Form: STAT:QUES:COND? Long Form: STATus:QUEStionable:CONDition?
Return Value: <int_value> actual register value
Description: Returns the value of the Questionable Condition Register (see Table B-3). The Questionable
Condition Register contains unlatched real-time information about questionable conditions of the
power supply. Bit set to 1 = condition (active, true); bit reset to 0 = condition (inactive, false). (See
example, Figure B-2.)
