StarLab – antenna characterisation
About
StarLab is the ultimate tool for antenna pattern measurements in laboratories and production environments where space is limited, cost is critical, and the flexibility of a portable system is required.
Description
StarLab uses an Active Switching Unit to switch between near-field passive measurement and over type of measurements. For near-field passive measurements, a Vector Network Analyzer is used as the RF source/ receiver. The Control Unit drives the two positioning motors and the electronic scanning of the probe arrays.
The amplification unit amplifies the signal on transmission and reception channels according to the frequency bands. The Transfer Switching Unit is used to switch between the emission by AUT and the reception by AUT modes. The power and control unit supplies the power and drives the RF units.
