SIMULATES THE EFFECT OF COAXIAL CABLE IN SERIAL DIGITAL SYSTEMS

The CABLE CLONE has similar attenuation vs frequency characteristics to coax cable over the wide frequency spectrum of the serial digital signal. When installing or testing serial digital equipment it is often necessary to establish the maximum length of cable over which the signal will remain useable, or to ensure there is sufficient margin (headroom) if a certain length of cable is required. Most adaptive equalisers, in deserialisers for example, rely on the attenuation characteristics of the cable to operate correctly.

At present the only way to do this is to insert the actual length of cable into the path. This is time consuming, inconvenient and costly.

The Faraday CABLE CLONE is the solution to the problem.

The Faraday CABLE CLONE emulates the loss and group delay frequency characteristics of a cable to approximately 360 MHz. It is supplied in a metal box fitted with BNC connectors which needs no power supply. It my be carried in the pocket and is always ready for immediate use.

Apart from the smaller space requirements of the cable clone (vs cable) it offers the advantage that comparable measurements become possible since the influence of manufacturing tolerances, customary in the case of coaxial cables, is abolished.
