B.62 STATus:OPERation:ENABLe COMMAND STAT:OPER:ENAB
Syntax: Short Form: STAT:OPER:ENAB <int_value> 0 to 1313 (1 + 32 + 256 + 1024)
Long Form: STATus:OPERation:ENABle <int_value> 0 to 1313 (1 + 32 + 256 + 1024)
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-6.)
FIGURE B-6. USING STATUS COMMANDS AND QUERIES
B.63 STATus:OPERation: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-6.)
B.64 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. 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 example, Figure B-
6.)
NOTE: The power supply is assumed to be operating in CV (constant voltage) mode.
OUTP ON Output enabled.
VOLT 3;CURR 1E-2 Power supply programmed to 3V, 0.01A.
STAT:OPER:ENAB 1056 Mask enabled for CC, WTG and bits.
STAT:OPER:ENAB? Returns 1056 (32 + 1024) (CC, WTG bits set).
STAT:QUES:ENAB 3 Mask enabled for OV and OC bits (1 + 2).
STAT:QUES:ENAB? Returns 3 (1 + 2) indicating OV and OC bits are enabled.
STAT:PRES Operation Condition Enable and Questionable Condition Enable registers
are preset.
INIT:CONT ON Continuous triggers enabled.
STAT:OPER:COND? Power supply returns 288 (256 + 32) to indicate that power
supply is constant voltage mode and Wait For Trigger is true.
--- MOMENTARILY SHORT POWER SUPPLY OUTPUT ---
STAT:OPER? Returns 1312, e.g., indicating that since the last reading of the
Operation Event Register the power supply has entered
Constant Current mode, the Wait Trigger was set.
STAT:OPER? Returns 0 indicating no changes since previous reading of the
Operation Event register.
STAT:QUES? Returns 0 (no questionable conditions occurred since previous
reading
--- OVERTEMPERATURE CONDITION OCCURS
STAT:QUES? Returns 8 (overtemperature condition tripped since the last
STAT:QUES? query).
STAT:QUES:COND? Returns 8, (Power supply still in overtemperature condition).
STAT:QUES? Returns 0, (Power supply no longer in overtemperature
condition).
STAT:QUES:COND? Returns 8, (Power supply still in overtemperature condition).
SYST:ERR? Power supply returns 0,“No error” message.
