Cobalt is AESA’s high precision balunless
measurement system for LAN cables.
Its unique single-ended way of measuring
makes full dynamic range available and
works over the full frequency range (>4
GHz), avoiding additional losses due to
balun.
A high-tech switching with at least two
million cycles secures stable, repeatable
and highly accurate measurements. Easy
to operate, the highly modular Cobalt is
now a well-known partner for LAN cable
measurements.
Aesa has added a technical innovation
with a recently developed feature:
patchcord adapters that allow using the
benefits of a balunless system combined
with the ability of patchcord testing.
Single ended and mixed mode
parameters are accessible to deliver more
information about the patchcord.
The new adapters use an easy interface
and can be mounted or removed in a few
seconds from the Cobalt cable interface.
The measurement can be performed
automatically from both sides according to
customer specification or standard values.
If requested, many additional parameters
can easily be taken into account, for
example insertion loss, TCL or in pair
skew.
As AESA is an ISO 17025 certified
company, the highest accuracy can be
expected for patchcord testing. Including
de-embedding method allows removal
of the adapters mathematically and
provides the opportunity to use any other
connector if required.
Cable manufacturers produce not
only wires, but also stranded, flexible,
sector-shaped and insulated conductors,
among others.
Measuring them requires additional
skills and constraints, otherwise results
are not repeatable or even incorrect.
Using integrated equipment allows
mastering of the uncertainties related to
the connecting device, then ensuring the
overall measurement, on the line or in the
laboratory.
The ResTest family (linear resistance
bridges) now consists of four integrated
pieces of equipment developed in this
perspective.
