(<NRf>) that is sent with the command. For example, to program the Arm (B6) and Trig (B5)
operation events for positive transitions, send the following command:
:stat:oper:ptr 96
where; Arm (bit B6) = 64
Trig (bit B5) = 32
<NRf> = 96
Effects of positive transitions on the Operation Event Register:
Positive Transition Effect On
Operation Event Operation Event Register
Settling Sets B1 at the start of the settling period.
Trigger Layer Sets B5 when waiting in the Trigger Layer.
Arm Layer Sets B6 when waiting in an Arm Layer.
Idle Sets B10 when entering the idle state.
