Impedance & Bandwidth Measurements of '2-strip anode test plate' gap – 9.6 mm trace width - 6 mm
Simulation Inputs: signal line geometry glass dielectric glass thickness find ~45 Ohms
scope screenshots 10/9/09 0 ohm termination open line
41 ohm termination
50 ohm termination – best matching, close to simulation
57 ohm termination
Bandwidth estimation (50 ohms) send in edge – pulser -> t-line -> scope rising time (10-90%) ~ 250 ps pulser -> scope rising time ~160 ps add rising time contributions in quadrature: t2total=t2instrument + t2line ------> tline = 190 ps 3 dB BW ~ 1.8 GHz
