STATus:QUEStionable:PTRansition?
Sets and queries the value of the NTR (Negative-Transition) and PTR (Positive-Transition) registers.
These registers serve as a polarity filter between the Questionable Condition and Questionable Event
registers.
When a bit in the NTR register is 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 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.
The STATus:PRESet command sets all bits in the PTR registers and clears all bits in the NTR registers.
Parameter Typical Return
Decimal sum of the bits in the register, default 0. For example, to enable bit 2 (value 4), bit 3 (value 8), and
bit 7 (value 128), use decimal sum 140 (4 + 8 + 128). Default 0. < bit value >
Enable bits 3 and 4 in the questionable PTR register: 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
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
Questionable Condition register can set the corresponding bit in the Questionable Event register.
The value returned is the binary-weighted sum of all bits set in the register.
