A Smith Chart design tool, this package has been updated to help the reader design impedance matching circuits. Version 4.0 contains new features such as double-matching capability, two-element circuit quick match, goodness of match readout, circuit Q matching, and target VSWR profile. This version also boasts improved printer output, new selections and retaining preferences out of screen colours, toolbar access to operations, and input/output improvements. Compatible with Windows 95 (or later) and Windows NT, the 32-bit code operates with video speed. The software can be used to match antennas, circuits and so on; evaluate circuit bandwidth response; examine alternative circuit designs; and perform cross-talk evaluations for ICs. It also includes an IEEE 488 bus interface capability that allows you to collect and transfer measured impedance data quickly from any GPIB-capable network analyzer (NI and Agilent 488 cards supported).
