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.
