measuring signals and analyzing Profibus network communication. It is powered by battery and provides graphic display, which can quickly obtain results when working in independent mode. You can also choose to analyze the Profibus PA network. In addition, PROFIBUS tester 5 supports exporting test results for advanced analysis. In the can FD network, the signal reflection in the communication cable can be effectively eliminated only by ensuring the continuity of the cable impedance. Therefore, in the process of designing the network topology, a 120 Ω terminal resistance will be connected at the end of the can FD bus to suppress the reflection.
The resistance value of the terminal resistance must be within the range of 118 Ω ~ 132 Ω specified in ISO 11898 standard. Too large or too small resistance will have adverse effects on can FD communication. If the resistance value is too small, the signal amplitude will be too small, thus affecting the signal identification and the communication will be extremely unstable; If the resistance value is too large, the signal amplitude will be too large, and the signal overshoot will occur
