Smith V4.1
Overview
The software is split in two parts:
Smith-Chart and S-Plot
Smith-Chart
Features:
Matching ladder networks with capacitors, inductors, resistors, transformers, serial transmis-
sion lines and open or shorted stubs
Free settable normalization impedance for the Smith-Chart
Circles and contours for stability, noise figure, gain, VSWR and Q
Edit element values after insertion
Tune element values using sliders (Tuning Cockpit) NEW in V4.0
Sweep versus frequency or datapoints
Serial transmission line with loss
Export datapoint and circle info to ASCII-file for post-processing in spreadsheets or math soft-
ware
Import datapoints from S-parameter files (Touchstone, CITI, EZNEC)
Undo- and Redo-Function
Save and load designs (licensed version only)
Save netlist (licensed version only)
Print Smith-Chart, schematic, datapoints, circles and S-Plot graphs
Copy to clipboard for documentation purposes
Settings for color and line widths for all graphs
S-Plot
