B.23 STATus:QUEStionable:ENABle Command STAT:QUES:ENAB
Syntax: Short Form: STAT:QUES:ENAB <int_value> Long Form: STATus:QUESionable:ENABle <int_value>
Function: Programs Questionable Condition Enable Register.
Description: Programs Questionable Condition Enable Register (see Table B-3).The Questionable Condition
Enable 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-2.)
B.24 STATus:QUEStionable:ENABle? QUERY STAT:QUES:ENAB?
Syntax: Short Form: STAT:QUES:ENAB? Long Form: STATus:QUESionable:ENABle?
Return Value: <int_value> actual register value
Description: Reads Questionable Condition Enable Register (see Table B-3). Power supply returns value of
Questionable Condition Enable Register, indicating which conditions are being monitored. Bit set to 1
= function enabled (active, true); bit reset to 0 = function disabled (inactive, false). Related Com-
mands: STAT:QUES?. (See example, Figure B-2.)
NOTE:The power supply is assumed to be operating in cV (constant voltage) mode.
STAT:OPER:ENAB 1545Mask enabled for OL, RE, OT and VE bits.
STAT:OPER:ENAB? Returns 1545 (32 + 1024) (OL, RE, OT and VE bits set).
STAT:PRES Operation Condition and Questionable Condition registers are
reset.
INIT:CONT ON Continuous triggers enabled.
STAT:OPER:COND? Power supply returns 768 (256 + 512) to indicate that power
supply is constant voltage mode and relays are closed.
STAT:OPER? Returns 1536, e.g., (1024 + 512) indicating that since the last reading
of the Operation Event Register the power supply has entered
Constant Current mode, the relays are still closed
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 3 (overcurrent protection tripped since the last
STAT:QUES? query).
STAT:QUES:COND? Returns 3, (Power supply still in overcurrent protection state).
STAT:QUES? Returns 0, (Register cleared by previous STAT:QUES?).
STAT:QUES:COND? Returns 3, (Power supply still in overtemperature state).
--- Overtemperature condition cleared.
STAT:QUES:COND? Returns 0.
SYST:ERR? Power supply returns 0,“No error” message.
