Mini Compact Range

The Mini-Compact Range and chamber assembly has been designed to enable cost effective millimetre and microwave antenna testing, with a quiet zone diameter up to 0.5 m. The system provides a compact, accessible test tool for small antenna designs. It is particularly well suited for high frequency antenna measurements and production testing. A complete system (RF, VNA, controller, camera, ventilation, PC, etc.) can be powered up with a single touch.

The basic configuration allows for full 3-D patterns to be collected using standard Vector Network Analysers. The chamber provides a modest level of shielding and easy access to the DUT positioner and compact range feed area. The smaller models (CR-M8, CR-M12) are portable, and mounted on a caster assembly for convenient transportation between different production or test sites.

A compact range feed polarization rotator enables the transmit polarization to be changed during a single test or in between tests. Linked axis motion of the transmit rotator and roll axis allows for automatic acquisition of E & H plane patterns in a single test. A squint (elevation) axis allows E&H plane patterns through the peak of the beam in case electrical and mechanical boresight do not coincide. The AL-4160 series controller supports the control of up to four (4) axes, and allows for simultaneous motion if required.

The data acquisition and analysis workstation comes equipped with MVG software, allowing for a versatile and powerful data acquisition and analysis tool for microwave antenna measurements. Upon request, the compact range reflector and positioner system without the installation of a compact anechoic chamber can be procured by customers with existing anechoic chambers.
