 STAT:OPER:ENAB
 This command and its query set and read the value of the Operational Enable register.  This register is a mask for enabling
specific bits from the Operation Event register to set the operation summary bit (OPER) of the Status Byte register.  This bit
(bit 7) is the logical OR of all the Operational Event register bits that are enabled by the Status Operation Enable register.
 Command Syntax STATus:OPERation:ENABle <NRf>
 Parameters 0 to 32,767
 Suffix (None)
 Default Value 0
 Examples STAT:OPER:ENAB 1312     STAT:OPER:ENAB 1 
 Query Syntax STATus:OPERation:ENABle?
 Returned Parameters <NR1>      (Register value)
 Related Commands STAT:OPER:EVEN
 STAT:OPER NTR/PTR Commands
 These commands set or read the value of the Operation NTR (Negative-T r ansition) and PTR (Positive-Transition) registers.
These registers serve as polarity filters between the Operation Enable and Operation Event registers to cause the following
actions:
lWhen 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.
lWhen 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.
lIf 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.
lIf 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.
