STATus:QUEStionable<1|2>[: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/or PTR filter. Reading the
Questionable Status Event register clears it.
Parameter Typical Return
(none) <bit value>
Read questionable status event register #1: STAT:QUES1?
l The value returned is the binary-weighted sum of all bits set in the register. For example, to
enable bit 2 (decimal value = 4), bit 4 (decimal value = 16), the corresponding decimal value would
be 20 (4 + 16).
l *RST has no effect on this register.
STATus:QUEStionable<1|2>: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) <bitvalue>
Read questionable status condition register #1: STAT:QUES1:COND?
l The value returned is the binary-weighted sum of all bits set in the register. For example, to
enable bit 2 (decimal value = 4), bit 4 (decimal value = 16), the corresponding decimal value would
be 20 (4 + 16).
l The condition register bits reflect the current condition. If a condition goes away, the cor-
responding bit is cleared.
l *RST clears this register, other than those bits where the condition still exists after *RST.
STATus:QUEStionable<1|2>:ENABle <value>
STATus:QUEStionable<1|2>:ENABle?
Sets the value of 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 corresponding to the binary-
weighted sum of the register's bits.
<bitvalue>
Enable bit2 and 4 in the questionable enable register #1: STAT:QUES1:ENAB 24
