| Txxxx p1 n1 p2 n2 Z0=impedance [TD=delay] [F=frequency [NL=norm_length]] |
| [rel=rel] [abs=abs] |
| p1 | Positive input port 1 |
| n1 | Negative input port 2 |
| p2 | Positive input port 1 |
| n2 | Negative input port 2 |
| impedance | characteristic impedance |
| delay | Line delay (Seconds) |
| frequency | Alternative means of specifying delay = norm_length/frequency |
| norm_length | See frequency. Default 0.25 if omitted. |
These remaining parameters control the way the line is simulated rather than its electrical characteristics. More accurate results (at the expense of simulation time) can be obtained by using lower values.
| rel | Relative rate of change of derivative for breakpoint |
| abs | Absolute rate of change of derivative for breakpoint |
The above line has an impedance of 50$\Omega$ and a delay of 1$\mu$S.
