C.29 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 C-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 C-5.)
C.30 STATus:QUEStionable:ENABle COMMAND
STAT:QUES:ENAB
Syntax: Short Form: STAT:QUES:ENAB <int_value> Long Form: STATus:QUESionable:ENABle <int_value>
Description: Programs Questionable Condition Enable Register (see Table C-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 C-5.)
C.31 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 C-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-

C.32 STATus:QUEStionable:INSTrument? QUERY
STAT:QUES:INST?
Syntax: Short Form: STAT:QUES:INST? Long Form: STATus:QUESionable:INSTrument?
Return Value: <int_value> actual register value
Description: Reads Questionable Instrument Register 0 (see Table C-4). Unit returns value of Instrument Regis-
ter 0 (inst register). The bits of this register are set when at leat one bit in the specified channel’s ISUM
register was set previously and the specific enable bit was also set. When this register is read, bits 1 -
