STATus:OPERation: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 Operation Condition and Operation 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 Operation Condition
register causes that bit in the Operation 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 Operation Condition
register causes that bit in the Operation Event register to be set.
STATus:PRESet sets all bits in the PTR registers and clears all bits in the NTR registers.
Parameter Typical Return
A decimal value that corresponds to the binary-
weighted sum of the bits in the register.
<bit value>
Enable bit 3 and 4 in the NTR register: STAT:OPER:NTR 24
Enable bit 3 and 4 in the PTR register: STAT:OPER:PTR 24
l
If the same bits in both NTR and PTR registers are set to 1, then any transition of that bit at the Operation Condi-
tion register sets the corresponding bit in the Operation Event register.
l
If the same bits in both NTR and PTR registers are set to 0, then no transition of that bit at the Operation Condition
register can set the corresponding bit in the Operation Event register .
l
The value returned is the binary-weighted sum of all bits set in the register.
STATus:PRESet
Presets all Enable, PTR, and NTR registers.
