Kabeldämpfungssimulator mit einem passiven Netzwerk für serielle digitale Signalquellen

摘要

The simulator comprises a constant resistance, bridged-T passive network (28) to simulate the frequency-loss characteristics of a reference coaxial cable. The cable loss simulator (20, Fig. 1) is selectively coupled into the output path of the serial digital signal source (12) to simulate the serial digital signal after transmission through the reference coaxial cable. The cable loss simulator has a resistive input section 22 for impedance matching with the serial digital signal source and a bridged-T section 28 with multiple breakpoints to simulate the frequency-loss characteristic of the reference coaxial cable. <IMAGE>
