Operation Event Register:
Bit B0, Calibrating (Cal)
Set bit indicates that the instrument is calibrating (PTR), or cali-
bration is complete (NTR).
Bit B1, Settling (Set)
Set bit indicates that the instrument is waiting for signals to settle
(PTR), or the settling period has expired (NTR).
Bits B2, B3 and B4
Not used.
Bit B5, Waiting for Trigger (Trig)
Set bit indicates that the instrument is waiting in the trig-
ger layer (PTR) of the trigger model, or that it has left the trigger layer (NTR).
Bit B6, Waiting for Arm (Arm)
Set bit indicates that the instrument is waiting in an arm
layer of the trigger model (PTR), or operation has proceeded from the arm layers into the trigger
layer (NTR).
Bits B7 and B8
Not used.
Bit B9, Calculating (Calc)
Set bit indicates that the instrument is performing a math calcu-
lation (PTR) or the calculation is complete (NTR).
Bit B10, Idle
Set bit indicates that the instrument is in the idle state (PTR), or has left the idle
state to perform an operation (NTR).
Bits B11 through B15
Not used.
