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

PF OC OV 
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.
