STAT:OPER:NTR
STAT:OPER:PTR
These commands set or read the value of the Operation NTR (Negative-Transition) and PTR (Positive-Transition) registers.
These registers serve as polarity filters between the Operation Enable and Operation Event registers to cause the following
actions:
•
When a bit in the Operation 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 of the Operation 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.
•
If the same bits in both NTR and PTR registers are set to 1, then any transition of that bit at the Operation
Condition register sets the corresponding bit in the Operation Event register.
•
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.
Note Setting a bit in the value of the PTR or NTR filter can of itself generate positive or negative events in the
corresponding Operation Event register.

NU = (Not used); OC = Overcurrent protection circuit has tripped.
OT = Overtemperature status condition exists; OV = Overvoltage protection circuit has tripped.
RI = Remote inhibit is active; UNR = Power supply output is unregulated.
Note: See "Chapter 4 - Status Reporting" for more explanation of these registers.
STAT:OUES?
This query returns the value of the Questionable Event register. The Event register is a read-only register which holds
(latches) all events that are passed by the Questionable NTR and/or PTR filter. Reading the Questionable Event register
clears it.
