Bit B14, Command Warning (Warn) — Set bit indicates that a Signal Oriented Measurement
Command parameter has been ignored (PTR), or a subsequent Signal Oriented Measurement
Command has executed successfully (NTR).
Note: Whenever a questionable event occurs, the ERR annunciator will turn on. The annunciator
will turn off when the questionable event clears.
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 and B3 — Not used.
Bits B4 Measuring (Meas) — Set bit indicates that the instrument is actively measuring (PTR),
or the measurement has finished.
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, B8 and B9 — Not used.
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.
