A Touchstone file containing the S-parameters of a n-port system.
Extension of the n-port Touchstone file.
Display type:
SPAR | — | Display TDR and TDT waveforms. |
IMPD | — | Display impedance profile. |
TDWF | — | Display total waveform. |
Excitation source:
STEP | — | Step-like source (default). |
IMPU | — | Gaussian impulse. |
Control key:
Off | — | No display of the source waveform (default). |
On | — | Display the source waveform. |
Number of interpolation points for Fast Fourier Transformation. It must be an integer power of 2. NFTT must be greater than or equal to 256 and less than or equal to 4096. Defaults to 512.
Source beginning time in seconds. Defaults to 0.
Source rise time. For a step-like source, it is the time from 10% of the rise to 90% of the rise. For a Gaussian impulse, it is the time from 50% of the rise to 50% of the rise. The rise time must be greater than or equal to 5 time steps. If the TRISE input is less than 5 time steps, it is changed to 5 time steps. Defaults to 5 time steps.
Driven port number. Defaults to 1.
Output port number. Defaults to 1.
Driven port number. No default.
Output port number. No default.
Driven port number. No default.
Output port number. No default.
Driven port number. No default.
Output port number. No default.
The time step is given by dt = 1/(2fmax) where fmax is the maximum frequency.
