Abstract

An antenna far field testing system comprises a master control computer, a network switch, a network trigger box, a network analyzer, and a rotary table controller; wherein, the master control computer is connected with the network switch; and the network switch is respectively connected to the network trigger box, the network analyzer, and the rotary table controller. The utility model integrates rotary table control, instrument operation and control, numerical processing and analysis, computer software programming, and so on into a complete organism, so as to form a set of far field testing system with a high technical level at home so far. The antenna far field testing system can realize synchronous control and acquisition of data measurement and rotary table angle information, can enable a drawn tested antenna pattern to be more accurate, and can enable parameter analysis for the tested antenna to be more accurate and reliable. In addition, a far field environment test of the antenna far field testing system can truly reflect performance parameters of the tested antenna in practical use.

Description

A kind of antenna far field test macro
Technical field
The utility model belongs to the antenna measurement technical field, especially a kind of antenna far field test macro.
Background technology
Antenna is the electronic information essential important component, all be unable to do without antenna to the phased-array radar with thousands of radiating elements greatly to mobile phone for a short time, and the antenna measurement technology has become one of core technology of development electronic information.In the face of of a great variety, enormous amount radio-frequency antenna; Antenna measurement Equipment Market potentiality are inestimable; It is many to be engaged in antenna measurement technical research producer abroad; More famous have companies such as U.S. MIT and Agilent, they all have the Antenna testing system product of oneself, but also do not have a tame specialty to do the Antenna testing system product at home at present.External antenna measurement series products price is very expensive, and maintenance cost is than higher, and the product composition has certain limitation, needs the special messenger to instruct training during use.
The utility model content
The purpose of the utility model is to overcome the shortcoming of above-mentioned prior art, and a kind of antenna far field test macro is provided, and this test macro is based on the Antenna testing system of radio frequency integrated vector network analyzer.This systematic survey project has comprised parameters such as antenna radiation pattern, half-power beam width, gain, direction coefficient, magnitude-phase characteristics.
The purpose of the utility model solves through following technical scheme:
This antenna far field test macro comprises main control computer, the network switch, network-triggered box, network analyzer and turntable controller; Said main control computer connects the network switch; The said network switch is connected to said network-triggered box, network analyzer and turntable controller respectively.
The above-mentioned network switch through netting twine interface and netting twine respectively with network-triggered box, network analyzer and turntable controller.
The above-mentioned network switch is connected with said main control computer through netting twine.
Above-mentioned turntable controller is connected with turntable.
The utlity model has following beneficial effect:
The utility model comprehensively is a complete organism with many aspects such as turntable control, instrumentation and control, numerical value processing and analysis, computer software programmings, is that an at present domestic cover technical merit is than higher far field test macro.This system can make DATA REASONING and turntable angle information realize the synchro control collection, and the tested antenna radiation pattern of drafting is more accurate, and is more accurately reliable to the parameter analysis of tested antenna.Its far field environmental testing has reflected the performance parameter of tested antenna in practical application really.
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.
