How to reduce network manufacturing test costs

Cellular base stations and remote radio heads are generally tested in a number of different ways. Radio performance is validated using general purpose RF test equipment such as signal generators, spectrum and network analysers, often assembled into a PXI modular test system and programmed to carry out a series of tests on RF functionality using appropriate modulated signals. Performance in the network can be tested by emulating multiple user devices under various operating scenarios.

With the densification of the network and the advent of more small cells, the spotlight is now on base station manufacturing costs and how to reduce them. So how can we make manufacturing test more cost effective?

Needing to test high volumes of its own remote radio head (RRH) products, AceAxis set out to design a tester to meet this challenge. The result is the AceAxis Advanced Radio Tester (ART), which contains all the necessary RF and baseband functionality for fast, repeatable and traceable testing within a single compact box.

A rich set of multiple simultaneous uplink and downlink measurements can be captured, logged and displayed, either on a dedicated PC or as part of a larger ATE system. Supporting software enables rapid deployment and integration into an existing test environment. Fast test times, a small footprint and swift set-up times simplify ramp-up and enhance product throughput.

The ART directly addresses the challenge of reducing manufacturing CAPEX and OPEX costs, incorporating RF functionality that is usually only found in more expensive discrete RF test equipment. In addition, the inclusion of two small form-factor pluggable interfaces (SFP) enables direct optical connection to the RRH.
