STATus:OPERation:NTR <value>
STATus:OPERation:PTR <value>
STATus:OPERation:NTR?
STATus:OPERation: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 Condition
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.
The Preset value are: NTR = 0; PTR = 32767
STATus:QUEStionable[:EVENt]?
This query returns the value of the Questionable Event register. The
Event register is a read-only register, which stores (latches) all events
that are passed by the Questionable NTR and/or PTR filter. Reading
the Questionable Event register clears it. The bit configuration of the
Questionable status registers is as follows:
Bit Position 15-11 10 9 8-5 4 3 2 1 0

UNR = The output is unregulated
INH = The output is turned off by one of the external J1 inhibit signals
OT = The output is disabled by the over-temperature protection
PF = The output is disabled because AC power has failed
OC = The output is disabled by the over-current protection
OV = The output is disabled by the over-voltage protection
STATus:QUEStionable:CONDition?
This query returns the value of the Questionable Condition register.
That is a read-only register, which holds the real-time (unlatched)
questionable status of the power supply.
