Separate tests: Testing the signal edges

Abbreviations for these separate tests in the "Device xx" window:
• Rising edge CAN_H
• Falling edge CAN_H
• Rising edge CAN_L
• Falling edge CAN_L
Each device on SafetyBUS p is tested to ensure the signals it is sending
have the correct edges. The rise and fall time of the signals on CAN_H and
CAN_L are measured.
Fig. 5-11: Rise/fall time
The measured time is shown in the detailed display of the result from
these separate tests.
Example for "Rising edge CAN_H":
