U4 DRIVE TEST (SENSOR DROP-OUT)

- Use the NGS to monitor only the rear wheel speed while driving at various speeds.

NOTE: Recording the speeds for later plotting will eliminate the need to monitor the NGS while driving.

Does the rear wheel speed signal suddenly drop out and return within one frame (.001 sec) on the NGS?
