Gekko - Portable Phased Array System

 

 

Gekko is the first portable phased array system that brings cutting-edge technology like matrix array control and real-time custom Total Focussing Methods (TFM) into the field, packed in a rugged, compact housing.

 

 

 

 

The powerful hardware is used to full capacity by highly elaborated software modules. In particular, the latest CIVA software features are natively implemented for beam steering and measurement analysis. By this way, smart arrays and 3D imaging can be supported for maximum adaptability to the most demanding testing tasks.

 

 

In order to give full profit of its capabilities to a large variety of users, the Gekko is designed as an “all-level operators” instrument. Supervisors and engineers will find the full panel of programming tools and set-up parameter tables they are used to in matrix array or TFM control. At the same time, level-1 operators will be supported in their testing tasks by easy to follow step-by-step interfaces, application and calibration wizards, automatic probe detection and reporting tools, which will speed up the operation and simultaneously reduce the error risk.

 

 

As a portable system, the Gekko is fully adapted to tough field conditions. Battery operated, equipped with a touch screen and water & dust resistant the instrument is supporting up to 4 hours of work in the field with a set of two batteries. Hot swap of batteries is possible.
