In serial digital applications it is known that a
signal adhering to the amplitude specification
of 800mV + 10% will maintain its integrity if
the attenuation at the Nyquist frequency is
30dB or less. It may then be reconstituted
correctly by, say, the Sony deserialiser.
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 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.
