STATus Commands
STATus:QUEStionable[:EVENt]?
Queries the event register for the Questionable Status group. This is a read-only register, which stores (latches) all
events that are passed by the Operation NTR and PTR filter. Reading the Questionable Status Event register clears it.
Parameter Typical Return
(none) <bit value>
Read questionable status event register: STAT:QUES?
l *RST has no effect on this register.
l The value returned is the binary-weighted sum of all bits set in the register.
STATus:QUEStionable:CONDition?
Queries the condition register for the Questionable Status group. This is a read-only register, which holds the live
(unlatched) operational status of the instrument. Reading the Questionable Status Condition register does not clear it.
Parameter Typical Return
(none) <bit value>
Read questionable status condition register: STAT:QUES:COND?
l The condition register bits reflect the current condition. If a condition goes away, the corresponding bit is cleared.
l *RST clears this register, other than those bits where the condition still exists after *RST.
l The value returned is the binary-weighted sum of all bits set in the register.
STATus:QUEStionable:ENABle <value>
STATus:QUEStionable:ENABle?
Sets and queries bits in the enable register for the Questionable Status group. The enable register is a mask for
enabling specific bits from the Operation Event register to set the QUES (questionable summary) bit of the Status Byte
register. STATus:PRESet clears all bits in the enable register.
Parameter Typical Return
A decimal value that corresponds to the binary-
weighted sum of the bits in the register.
<bit value>
Enable bit 2 and 4 in the questionable enable register: STAT:QUES:ENAB 24
l *CLS does not clear the enable register, but does clear the event register.
