F9 Systems CalBlade
The CalBlade backplane calibration fixture isdesigned to permit accurate and convenient impedance and transmission measurements of a HM-Zd backplane. The CalBlade is used to calibratethe logic card connector interface to the backplane rather than to the usual far-end of the coaxial measurement cables. Very accurate impedance, skew and propagation delay measurements are possible since parasitic fixturing effects are removed.
