Unique measurement from Aesa

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. Aesa Cortaillod – Switzerland Website : www.aesa-cortaillod.com

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. 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. 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 HEADING TO INTERWIRE?
