Abstract
A cable loss simulator for a serial digital signal source adapts a constant resistance, bridged-T passive network to simulate the frequency-loss characteristics of a reference coaxial cable. The cable loss simulator is selectively coupled into the output path of the serial digital signal source to simulate the serial digital signal after transmission through the reference coaxial cable. The cable loss simulator has a resistive input section for impedance matching with the serial digital signal source and a bridged-T section with multiple breakpoints to simulate the frequency-loss characteristic of the reference coaxial cable.
