Si9000 Transmission Line Field Solver
The Polar Instruments Si9000 Transmission Line Field Solver incorporates
fast and accurate frequency-dependent PCB transmission line modelling. The
Si9000 provides for both lossless and frequency-dependent modelling and
extracts full transmission line parameters for a wide range of PCB
transmission lines. The Si9000 uses advanced field solving methods to
calculate PCB trace impedance for most single-ended and differential
circuit designs. Based on Boundary Element analysis, the Field Solver is
able to provide rapid modelling for a wide range of microstrip, stripline
and coplanar structures.
Lossless calculations
The Field Solver provides for rapid calculation of single PCB trace
impedance values against significant PCB parameters (e.g. trace height an
