Test, into test interface, while magnetic interference situation in observing interface, and starts under without high-intensity magnetic field disturbed condition test.
Need away from antenna to place instrument vertically after clicking on start button, hear prompt tone " instrument is moved into antenna medium position "
By instrument, radian moves to antenna medium position clockwise or counterclockwise afterwards, waits instrument prompting test to terminate, clicks on and preserve.Together
When click on antenna parameter information, LAC, CID, BCCH, BSIC, RXLeV of current area and multiple neighbor cells can be tested out
Information.Per strip antenna after the completion of test, bottom shoot button can be clicked on the overlay area of every fan antenna is taken pictures, click is swept
Retouch, can scanning antenna back bar code information, while scanning result is attached under this test event.Antenna attitude is tested
The data measured, then control unit is fed back to, compensate the radiating element of antenna.The use of antenna attitude tester is by operation
On the spot, work high above the ground has been manually done personnel, this work there is certain risk and be limited to geographical environment and weather because
Element, in this way antenna tilt correction make to a certain extent network be in unoptimizable state time it is elongated, together
When add network operation cost.
