Description of drawings
Fig. 1 is that the equipment of the utility model connects block diagram.
Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
Referring to Fig. 1, the antenna far field test macro of the utility model comprises main control computer, the network switch, network-triggered box, network analyzer and turntable controller; Main control computer connects the network switch; The network switch is connected to said network-triggered box, network analyzer and turntable controller respectively.The said network switch through netting twine interface and netting twine respectively with network-triggered box, network analyzer and turntable controller.The network switch also is connected with said main control computer through netting twine.
The principle of work of the utility model is following:
Because only needing before test, to configure maintenance, the transmitting terminal turntable gets final product; In the course of work of test macro; Need carry out synchro control to three processes; The uniform rotation, the signal generating module that are turntable respectively transmit and receiver collection measured signal, guarantee on each angle, to have the data of even number.
In test macro, pass through software configuration data acquisition module on main control computer; Data acquisition module receives the location triggered signal from turntable through turntable controller; Write down the positional information of turntable and the data that network analyzer collects simultaneously, each group positional information is corresponding one by one with the aerial signal that receives when guaranteeing antenna measurement.
Main control computer connects the mode of motion that turntable controller is controlled turntable through network; Turntable sends trigger pulse on the set angle interval location; When data acquisition module receives pulse; Trigger network triggers box long-range simulation signal generator is set, and simulation signal generator is set and accomplished the back and trigger receiver and realize desired location and the test of setting frequency, after the test completion again trigger signal source switch to next frequency; Data acquisition module is realized the buffering of revolving table position and network analyzer test data, and the result is sent to testing software and demonstration.
Contact through trigger pip between signal source, network analyzer and the turntable becomes an organic whole, and test macro can collect the signal value that antenna receives under the signal source setpoint frequency accurately on each stepping point of turntable.
