Setup Smith V3.10.pdf

What’s New Smith V3.10May 2010 Smith-Chart New Features: ? Sweep versus frequency or datapoints ? Serial transmission line with loss ? Export datapoint and circle info to ASCII-file for post-processing in spreadsheets or math software S-Plot New Features: ? Linear or logarithmic frequency axis ? cursor readout at gain and return loss graphs. System requirements: Windows XP, Windows Vista, Windows 7 .NET Framework 3.5 Sweeps There are two possibilities to sweep a network: ? Frequency sweep ? Datapoint Sweep Use menu “Extras”, “Sweep” (“Remove Sweep”) or button in toolbox to invoke or clear a sweep. Before doing a sweep design a network starting from one datapoint For datapoint sweep all . datapoints must be input before starting a sweep. Frequency sweep Example: At 400 MHz match 25 ? to 50 ??using a 6 element lowpass. Use a frequency sweep from 300 MH 800 MH fi d h hi f (VSWR) f hi k z to z to n out t e matc ng per ormance or t s networ versus the frequency range from 300 MHz to 800 MHz. ? After invoke of a sweep, edit element values to watch changes of swept points. Datapoint sweep Example: An antenna has different impedances at different frequencies. This datapoints are loaded from S11 fil M h h 1 9 GH 50 ?? i 50 ?? i i li d a - e. atc t e antenna at . z to us ng a transm ss on ne an a parallel capacitor. Use a datapoint sweep to find out the matching performance (VSWR) for this network for all datapoints. ? After invoke of a sweep, edit element values to watch changes of swept points. Serial transmission line with loss Example: An antenna has an impedance of (10-j35) ??at 450 MHz.
