Indoor anechoic chamber the size of the quiet zone should cover the antenna maximum size; the test distance should satisfy D = 2D2 / λ.

Install separate anti-static grounding, lightning protection cannot be accessed, the grounding resistance <3 ohms.

Equipment required 50Hz single-phase 220-volt AC power supply, power> 10KW.

Gain Repeatability: ± 0.5 dB

3dB beam width repeatability: BW of ± 5%

The first side lobe about accuracy: ± 0.8dB;

Than before Repeatability: ± 1.0dB

Inclination measurement repeatability accuracy: ± 0.3 °

XPD rate Repeatability: ± 1dB

Automatic Test Time (8-port antenna 80 TD frequency): ≤45 minutes

By each subsystem centralized computer control system, simple operation, friendly interface!

Due to the external electromagnetic environment, space reflection, weather, time constraints, to be based on the design scene.

Due to complex environmental conditions, measurement accuracy, and repeatability performance utilization is relatively weak, but less investment.
