Embodiment
The Wireless LAN product is before formal batch process, all can carry out small-scale trial production (pilotrun) earlier, and utilize spectrum analyzer (spectrum analyser) and power meter (power meter) the trial production product to be carried out the test analysis of the frequency (f) of certain number of times to response (Output response) relation of power output, till the characteristics of output power of finding out this test products really, what stored in the buffer this moment is still without the component value of crossing the Wi-Fi product of adjusting.Figure 2 shows that the response relation figure of the frequency of trial production product to power output, by finding among the figure that P1~P8 is the breakover point of power output, f1~f8 is the pairing frequency of P1~P8.Since a little frequencies (f1~f8) measured power output is unsettled, so the phenomenon of breakover point just occurs.In addition, aforesaid frequency is to the response of power output, it should be a continuous function, so when we the extreme value of part (breakover point position) when ideal value is approached, its neighbor also can be forced into towards ideal value simultaneously, whole continuous function is fallen in the permissible range, thus the present invention be by: (1) will be still without crossing in the component value write registers of adjusting; (2) under pairing each frequency of aforementioned power output breakover point, adjustment component value to the deviation of its power output and power output ideal value is to drop within the permissible range of tested product specification (spec.); (3) with the component value of adjusted Wi-Fi product again in the write registers; Thereby solve described known problem.
Fig. 3 is for the method flow diagram of Wi-Fi product adjustment power output of the present invention, to clearly demonstrate method of adjustment of the present invention; At first, will be without crossing in the component value write registers of adjusting (step 301); To the response relation figure of power output, find out power output breakover point (step 302) from the frequency of trial production product; Carry out power output frequency response test (step 303); Judge whether its output power value drops on the permissible range interior (step 304) of product specification; If, and finish operation (step 306) then with adjusted component value (step 305) in the write registers again; If not, then, adjust the buffer component value (step 307) of respective frequencies according to exporting it to the pairing frequency of breakover point; Get back to step 303 then and carry out the power output response test, step 304 judges whether its output power value drops in the permissible range of product specification, constantly repeat this circulation till its power output is satisfied the criteria, just with adjusted component value (step 305) in the write registers again, and finish operation (step 306).
When the frequency of trial production product is shown in Fig. 4 A the time to the response relation of power output, we are P1 as can be seen, P3, the power output of P7 is higher than desirable output power value (solid line IL among the figure), P2, P4, P5, P6, the power output of P8 is lower than desirable output power value, but because of P1, the power output of P7 is arranged between power output higher limit (figure dotted line HL) and the ideal value, the power output of P5 is arranged between power output lower limit (figure dotted line LL) and the ideal value, therefore, P1, P5 and P7 can not need adjust but P3 need adjust the component value of respective frequencies, power output is dropped between power output higher limit and the ideal value, same, P2, P4, P6 and P8 also need adjust the component value of respective frequencies, power output is risen between power output lower limit and the ideal value, thus, the output power value of Wi-Fi product can be up to specification, shown in Fig. 4 B.
What this should be specifically noted that be: (1) is owing among the response relation figure of frequency to power output that is done in the trial production stage, the power output that the breakover point place records is unstable, the side can turnover occur at this place, therefore, the main way of the present invention is just taken out the buffer value at breakover point place, and adjusts test in its power output meets the error permissible range of standard output power of tested product specification (802.11b) according to as above method; (2) in this trial production stage: the data of gained are to test gained with optimal sample (golden sample), and its product performance is that the product performance of producing in batches with institute of the present invention desire is identical.Method of adjustment of the present invention and old method are compared as follows shown in the table one:
