1. Impedance & Bandwidth Measurements of '2-strip anode test plate'
gap – 9.6 mm
trace width - 6 mm

2. Simulation
Inputs: signal line geometry
glass dielectric
glass thickness
find ~45 Ohms

3. scope screenshots 10/9/09 0 ohm termination open line input
reflections
0 ohm termination
open line

4. 41 ohm termination

5. 50 ohm termination – best matching,
close to simulation

6. 57 ohm termination

7. 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
