Grouping of tested cables.
| | Serial number | Test model | Cable characteristic impedance (Ω) | Cable terminal resistance (Ω) | Matching status of signal source and cable |
| | Test one | SYV1 | 50 | 50 | Match | | Test two | SYV4 | 75 | 75 | No impedance matching network, single-ended mismatch | | Test three | SYV4 | 75 | 75 | Connect to 50–75 impedance matching network, matching | | Test four | SYV4 | 75 | 50 | No impedance matching network, double-ended mismatch | | Test five | SYV4 | 75 | 50 | Connect to 50–75 impedance matching network, matching |
