  • Basic parameter:

                                     Probe number:  63+1/67+1

                                     Measurement Frequency range: 400MHz-6GHz,6GHz-18GHz

                                     Gain(10dBi)System test error(dB):

                                    0.4GHz-0.8GHz ≤±0.7;

                                    0.8GHz-1GHz ≤±0.5;

                                    1GHz-6GHz ≤±0.5;

                                    Gain(10dBi)System repeatability(dB):0.4GHz-6GHz ≤±0.3;

                                     Typical dynamic range:50dB-70dB

                                     Max size of DUT:2.75m

                                     Max weight of DUT: 70Kg

                                     Optional chamber shielding efficiency : ≤-110dB

                                     Optional anechoic chamber size: 5m*5m*5m,

                                                          6m*6m*6m,

                                                         7m*7m*7m

                                     Probe array diameter (inner diameter/waiibg): 3.2m/3.8m、4m/4.6m、5m/5.6m

                                    Multi-axis turntable: five axis turntable or two axis turntable

                                    Angle probe array: 5.3° / 5°

                                    Rotation accuracy:0.01°

 

  •  System advantage:

                                       Faster Measurement: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.

                                      Real-time display:It allows real-time viewing of passive directivity diagram as well as sensitivity.

                                      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.
