Detailed Product Description

Specifications

 

Adopt planar & cylindrical near-field measurement to measure the antenna, in order to obtain the antenna's performance parameter 
 

 

Working principle:
It adopts two test Ports of Vector Network Analyzer as the Input and output terminal of the
Near-Field measurement, Under the control of the host computer, meanwhile, through the
test probe on the scanner, output terminal transmits signals in a certain scanning mode
under the control of the driving device. At the same time, another port of tester collects test
data by using the antenna matrix and transfer the data to the master computer, then the
data processing system will analysis, diagnosis the Near-field characteristics of the
antenna matrix , and calculate the Far-field parameters. When perform cylindrical near-field measurement, the test antenna is mounted on the positioner, Under the control of the host computer, coordinate the positioner's rotating positioning, probe's scanning, and amplitude & phase data collection of the instruments. And then adopt cylindrical near-field data processing system to analysis, diagnosis the Near-field characteristics of the antenna matrix, and calculate the Far-field parameters .

 

System requires:
Working Frequency: 0.8~5GHz
Size of test antenna: 3.0m×0.35m
Effective scanning range: 4.5m×4.5m
Error of sidelobe measurement: <±1dB(-15dB,in sidelobe electric level)
Error of gain measurement: ≤ ± 0.5dB
Positioning accuracy: <±0.2mm
