    • DUTradiation diameter size(m):


  • System Characteristics:

                       Faster Measurement:  It allows real-time viewing of passive directivity pattern. As a symmetrical distribution of the probes is applied, the DUT can be 3D measured completely as long as a 180-degree rotation is performed horizontally under normal circumstances. Measurement functions are automatically performed by the supporting software, and measurement reports can be generated automatically.

                      Powerful function:It supports passive measurement with the frequency range between 400MHz and 6GHz, and supports both active and passive measurement of large antenna, especially suitable for BTS antenna measurement.
