STATus:QUEStionable<1|2>:ENABle?
enable register
Sets the value of the
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
A decimal value corresponding to the binary-
weighted sum of the register's bits.
Enable bit 2 and 4 in the questionable enable register #1: STAT:QUES1:ENAB 24
For example, with bit 2 (value 4) and bit 4 (value 16) set, the query returns +20.

These registers serve as a polarity filter between the Questionable Condition and Questionable Event
registers.
When a bit in the NTR register is set to 1, then a 1-to-0 transition of the corresponding bit in the
Questionable Condition register causes that bit in the Questionable Event register to be set.
When a bit in the PTR register is set to 1, then a 0-to-1 transition of the corresponding bit in the
Questionable Condition register causes that bit in the Questionable Event register to be set.
STATus:PRESet sets all bits in the PTR registers and clears all bits in the NTR registers.
Parameter
A decimal value corresponding to the binary-
weighted sum of the register's bits.
Enable bit 3 and 4 in the questionable NTR register #1: STAT:QUES:NTR 24
Enable bit 3 and 4 in the questionable PTR register #1: STAT:QUES:PTR 24
If the same bits in both NTR and PTR registers are set to 1, then any transition of that bit at the
l
Questionable Condition register sets the corresponding bit in the Questionable Event register.
If the same bits in both NTR and PTR registers are set to 0, then no transition of that bit at the Ques-
l
tionable Condition register can set the corresponding bit in the Questionable Event register.
The value returned is the binary-weighted sum of all enabled bits in the register.
