Operation Event Register:
Bit B0, Calibrating (Cal) — Set bit indicates that the instrument is calibrating (PTR), or cali-
bration is complete (NTR).
Bits B1, 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 calculating a reading
(PTR), or that the calculation is completed (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).
Bit B11, Sequence Test Running (Seq) — Set bit indicates that a Sequence Test is running
(PTR), or that the test has finished (NTR).
Bits B12 through B14 — Not used.
Bit B15 — Always zero.
