Calculations on a cable, one or two wires with otional shield.

The cable is simulated with a number of seperate RLC sections

C | Capacity between wires for one meter cable |

Cshield | Capacity between one wire and shield |

L | Inductance for one meter cable |

Rcable | DC resistance for one meter of wire |

Rshield | DC resistance for one meter of shield |

Length | Total length of cable |

Rs | Source impedance |

Rl | Load impedance |

Curve plot | Show a curveplot of frequence responce |

Waveforms | Try cable with different waveforms |

Input/output | Use a complex source/load network |

-3 dB Freq | This is calculated form RCL and ignoring any transmission line effects |

Cable Zo | Impedance of cable at specified frequence |

Signal velocity | Speed of signal at specified frequence, shown in absolute speed and percent of c |

Gain | Gain of cable (Will be below 1) |

Phase | Phase of output signal |

Signal in B | Crosstalk to B wire |

Phase of B | Phase of signal in B wire |

Signal in gnd | Signal in gnd connection |

Freq | Calculate cable parameters and transmission fr this frequence |

Volt (RMS) | Analyze with this voltage |

dBm | Specify signal as dB with reference at 1mW over 600 ohm |

RMS voltage | RMS voltage and dB level (Ref: 1mW over 600 ohm) |

Peak-peak voltage | Above value multiplied by sqrt(8) |

Slew rate | The maximum slew rate of the voltage |

Source cable i/Source cable current | Maximum current going into the cable to charge/discharge the cable capacity |

Source load current | Maximum current used to supply the load |

Noise floor | Comparing the signal to "Johnson" noise |

Limit | Used when calculating cutoff frequence, usual 3 dB |

Freq n | Analyze at these frequences, write DC to do a DC analyse |

Sections | How many section to do the calculations on, more sections give better result but are slower |

Zo | Impedance of cable |

C | Capacitance of cable |

R | DC resistance of cable |
