Eagleware has a fully equipped RF lab where networks are built and tested regularly. These models make it possible to simulate machined, stripline and microstrip combline and interdigital filters directly without manual user conversion to an equivalent circuit. Rectangular linear and log frequency plots, Smith charts and scaleable polar charts are supported.
Tunable markers provide for accurate readout even with graphical display.
Multiple Windows support such capabilities as placing a tunable filter in one Window and an oscillator circuit in a second Window. HP compatible plotters are also supported. Vector and pixel file formats for export to desktop publishing systems is supported for both DOS and Windows. You tune by tapping cursor keys and watching results update on screen. Optimization is truly amazing.
