Embodiment
Please with reference to Fig. 1, it illustrates the calcspar into Antenna testing system.Antenna testing system 10 is in order to checking multifrequency antenna 20.Antenna testing system 10 comprises proving installation 110, proving installation 120 and computing machine 130.Proving installation 110 and proving installation 120 are electrically connected to computing machine 130, with test multifrequency antenna 20.Wherein, proving installation 110 and proving installation 120 for example be respectively signal generator (Signal Generator, SG) and spectrum analyzer (Spectrum Analyzer, SA).
Please with reference to Fig. 2, it illustrates the synoptic diagram into a kind of frequency meter.Aforementioned frequency meter for example is shown in Figure 2.Frequency meter 30 can comprise stand-by period < Set Equipment wait time >, total test frequency number < Total Test Frequency Number >, predeterminated frequency Freq, standard gain Standard Gain and frequency spectrum level Spectrum Level.Computing machine 130 treats that according to the stand-by period of stand-by period < Set Equipment waittime>setting proving installation 120 the initial setting entering steady state (SS) of this proving installation begins to carry out frequency test again; And the test frequency number that total test frequency number < Total Test Frequency Number>expression multifrequency antenna 20 need be verified.
When multifrequency antenna 20 rotated to test angle, aforementioned computing machine 130 was set each test frequency that needs checking in regular turn according to the predeterminated frequency Freq of frequency meter 30, can accomplish the checking work of all test frequencies after making multifrequency antenna 20 only need revolve to turn around.In addition, aforementioned computing machine 130 is set proving installation 120 according to the frequency spectrum level Spectrum Level of frequency meter 30, to measure wireless signal.Computing machine 130 also obtains the corresponding antenna gain according to the standard of frequency meter 30 gain Standard Gain.
Please with reference to Fig. 3, it illustrates the method for testing into a kind of multifrequency antenna of accordinging to preferred embodiment of the present invention.Method of testing can be applicable to aforementioned Antenna testing system 10, and method of testing comprises the steps: at first shown in step 410 initialization test device 110 or proving installation 120.Proving installation 110 or proving installation 120 for example carry out initialization according to configuration file (Configuration File).
Then shown in step 420, whether the test angle of judging multifrequency antenna 20 is less than default value, and wherein default value for example is 360 degree.When the test angle of judging multifrequency antenna 20 less than default value, then execution in step 430.In step 430, the test frequency that computing machine 130 is set proving installations 110 and proving installation 120 according to frequency meter 30 equals a predeterminated frequency, to obtain multifrequency antenna 20 when this test angle, corresponding to the test result of this predeterminated frequency.In addition, computing machine 130 can also be set the datum of proving installation 120 according to frequency meter 30, so that proving installation 120 outputs test data exactly.
And then shown in step 440, judge whether to need to change test frequency.In step 440 be judge test frequency set point number whether greater than total test frequency number of this frequency meter, to judge whether to need to change test frequency.When set point number is not more than total test frequency number, need promptly to represent the change test frequency, and repeated execution of steps 430.Computing machine 130 and the test frequency of setting proving installation 110 and proving installation 120 according to frequency meter 30 equal another predeterminated frequency, to obtain multifrequency antenna 20 under same test angle, corresponding to the test result of this another predeterminated frequency.In addition, computing machine 130 can also be set the datum of proving installation 120 according to frequency meter 30, so that proving installation 120 outputs test data exactly.
On the contrary, when set point number greater than total test frequency number, i.e. expression need not change test frequency.This computer-chronograph 130 is set the predeterminated frequency in the frequency meter 30 in regular turn and is finished, and computing machine 130 also obtains under the same test angle, the corresponding test result of predeterminated frequency in all and the frequency meter 30.When set point number during greater than total test frequency number, can progressively increase the test angle of multifrequency antenna 20, and repeated execution of steps 420.
When test angle is not less than default value, represent promptly that multifrequency antenna 20 has revolved to turn around to finish.Computing machine 130 stores the corresponding test result of each predeterminated frequency respectively to different log files, and according to drawing antenna patterns illustrated figure in the corresponding test result of the test frequency of first cis-position with sorting.And other test frequency only needs can draw out corresponding antenna field pattern figure according to the log file of correspondence via software for drawing.
Please with reference to Fig. 4, it illustrates the thin portion process flow diagram into abovementioned steps 430.Abovementioned steps 430 comprises the steps: more further at first that shown in step 432 test frequency that computing machine 130 is set proving installations 110 and proving installation 120 according to frequency meter 30 equals predeterminated frequency.Then shown in step 434, computing machine 130 self-test devices 120 read the test data corresponding to this predeterminated frequency.And then shown in step 436, computing machine 130 calculates test result according to test data.Because computing machine 130 is set the different preset frequency to proving installation 110 and proving installation 120 according to frequency meter 30, therefore, computing machine 130 self-test devices 120 read the test data corresponding to different predeterminated frequencies.Computing machine 130 promptly calculates the test result corresponding to different predeterminated frequencies according to the test data corresponding to different predeterminated frequencies.
The method of testing of the multifrequency antenna that the above embodiment of the present invention disclosed; Set each test frequency of the required checking of multifrequency antenna according to frequency meter; Promptly accomplish the checking work of all test frequencies after making multifrequency antenna revolve to turn around, with the proving time of reducing multifrequency antenna significantly.
In sum, though the present invention discloses as above with preferred embodiment, so it is not in order to limit the present invention.Have common knowledge the knowledgeable in the technical field under the present invention, do not breaking away from the spirit and scope of the present invention, when doing various changes and retouching.Therefore, protection scope of the present invention is as the criterion when looking appended the claim scope person of defining.
