Large antenna measurement system, support active, passive antenna measurement, with 2.61 ° probe sampling density, measurement more accurate, especially suitable for base station antenna and large antenna measurements of DUT (diameter less than 3 m).

 

  • Basic parameter:

                                     Probe number:   127+1

                                     Measurement Frequency range: 400MHz-6GHz

                                     Typical dynamic range: 50dB-70dB

                                     Max size of DUT: 3.0m

                                     Max weight of DUT: 120Kg

                                     Reflection level of quiet zone :

                                     0.4GHz-0.6GHz<-35dB    0.6GHz-1GHz<-40dB     1GHz-6GHz<-45dB

                                     Optional chamber Shielding efficiency: >100dB

                                     Optional anechoic chamber size: 12m*10m*10m

                                     Probe array diameter (inner diameter) :4m

                                     Quiet zone diameter(0.4GHz-6GHz): 3.0m

                                     Multi-axis  Turntable:Horizontal rotation axis、Horizontal translation axis、Pitch axis、Oversampling axis(Optional DUT telescopic shaft).

 

  • System advantage :

                                           Faster measurement:It allows real-time viewing of  passive directivity diagram as well as sensitivity. In addition, the symmetrical distribution

                                           of probes is applied. Thus, the object can be 3D measured completely as long as a 180-degree rotation is performed horizontally under normal

                                           circumstances.

                                            Powerful function:It supports the passive measurement within the frequency range between 400MHz and 6GHz. It can support the

                                            measurement of large antenna, especially suitable for BTS antenna measurement.
