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.
