This graphics-intensive program is a valuable
transmission-line calculator for both advanced and
beginning users. Based on the venerable and highly
intuitive Smith chart, it provides high-accuracy
computations without recourse to paper, compass or
straightedge.
Here are the highlights of this program:
- Uses the full graphics capabilities of
the Windows ® operating system for network entry,
analysis controls and displayed results. Most notable are
the extensive zooming and panning capabilities of the
chart display.
- Allows real-time interaction with the
analysis computation in a seamless, intuitive manner with
changes in component values and operating frequency
immediately displayed.
- Analyzes networks composed of
transmission lines, stubs and lumped components (L's, C's
and R's) in both series-connected and shunt-connected
configurations.
- Program setups, including network
configurations, are stored offline for immediate
retrieval in an open, text-based format.
- Analysis results are displayed over
impedance or admittance coordinates or over
readily-apprehended overlays of both.
- Numeric readout of any point on the
chart in terms of impedance, admittance, complex
reflection coefficient, VSWR and return loss is available
at any time with a mouse click.
- In addition to displaying the results
of sweeping the operating frequency, those results are
also available in tabular form for input to other
analysis and synthesis programs.
- As an aid to designing
impedance-matching networks, a constant-VSWR circle and
constant-Q curves may be displayed.
