(6) 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
(7) Channel Balance
Record simulated 1000 Hz ½ reference level data for each channel 1,2,3 and 4 and
verify amplitude all within 3 dB.
Record simulated 1000 Hz 1/10 reference level data for each channel 1,2,3 and 4
and verify amplitude all within 3 dB.
Example report message(s):
