Rotor Speed
Part 1 – Record simulated 6000 Hz rotor speed data and verify data is within 2% of
sent frequency.
Part 2 – Record simulated 7 Hz rotor speed data and verify data is within 2% of sent
frequency.
Example report message(s):
08:03:52 PASSED Rotor Speed 6000 Hz (Expected 4 patterns > 5880.0 Hz <
6120.0 Hz) Results = 5998.0 Hz, 6026.4 Hz, 6026.4 Hz, 6026.4 Hz
08:04:03 PASSED Rotor Speed 7 Hz (Expected 4 patterns > 6.9 Hz < 7.1 Hz)
Results = 7.0 Hz, 7.0 Hz, 7.0 Hz, 7.0 Hz
