Fig. 4 then shows the embodiment functional block diagram of wireless signal measurement system of the present invention.
The wireless signal measurement system of legend has the signal source 401 producing signal, such as previous embodiment institute
Carrying, produced test signal by controlling end device, signal is inputted to treating by the signal input unit 402 of system
Survey device 403, test system 403 export send after treatment be loaded in specific electromagnetic wave frequency range
Wireless signal, is received by the signal receiving unit 404 in system, and is measured wherein signal strength signal intensity, as
Obtained the wireless signal received by signal strength measurement unit 405, such as measure wherein with RSSI table
The signal strength signal intensity shown.
According to embodiment, the invention discloses that the test of embodiment disclosed in book is divided into two benches, first stage
For the balance between test test system and test environment, wherein, signal strength measurement unit 405 is measured former
The signal strength signal intensity of test signal, compares with the signal strength signal intensity of the wireless signal of test system 403 output,
Particularly measure the signal strength signal intensity of same passage (channel), as in figure, the first comparing unit 406 compares
To test signal with after the signal strength values of wireless signal or its equal data, hardware can be carried out according to this
Adjustment unit 407.
If according to when there is no balance from the point of view of signal, such as being compared by a thresholding (being set to the first thresholding)
Relatively, i.e. adjustment test system, the hardware adjustment unit 407 in figure can include various signal line, contact,
Connector and tester table itself, be all probably and affect the unbalanced reason of signal, wherein grid line
Road (RJ-45) should use short-term, and uses tool trip to fix, and these all may affect test result,
Therefore, after adjustment test system, return reception signal and judge signal-balanced step.
Afterwards, confirmed signal-balanced after, then carry out second stage test, the purpose of second stage is logical
Crossing adjustment makes same test system same or like test all can be had to tie at different tester tables
Really, major way is to be tied the signal strength measurement of different platform by signal-conditioning unit (such as attenuator)
Fruit is executed signal and is adjusted so that result reaches unanimity, and it is hereby ensured the test to follow-up test system
Result will not have different results on different tester tables.
As obtained the signal strength signal intensity of the wireless signal of test system 403 output with the second comparing unit 408,
With this comparison sample data 410, the test result that sample data 410 is such as produced by other test systems,
And can be as the sample of adjustment other system after evaluated.If test result has with sample data 410
Certain gap, as assessed with certain threshold (being set to the second thresholding), then system is the most single according to second
The test result of unit 408 adjusts the pad value of signal adjustment unit 409, adjusts test system 403 with this
The wireless signal of output.
In this example, signal adjustment unit 409 is defeated with reception test system 403 for being located at each signal processing apparatus
Go out the attenuator on the signal receiving device of wireless signal, the attenuation of systemic presupposition can be provided with, maybe can lead to
Cross control end and perform adjustment, obtain the balance between different tester table, bag by adjusting signal attenuation
Include forward and compensate (positive compensation) and Contrary compensation (negative compensation),
When signal strength signal intensity is too high, Contrary compensation can be imposed；If signal strength signal intensity is too low, then imposes forward and compensate,
The signal between different platform is allowed to reach unanimity.
Similarly, the wireless signal measurement system disclosed by this example can be tested by test system 403 simultaneously
Output is loaded in the wireless signal of different frequency range, and wireless signal at least includes the letter carried by 2.4GHz frequency range
Number with the signal carried by 5GHz frequency range, by system with the identical or different each frequencies of host computer system processes
The signal of section, remakes out hardware adjustment or the assessment of pad value compensation.
Flow chart shown in Fig. 5 the most then describes the embodiment stream of wireless signal measurement system method for building up
Journey.
Step at the beginning, such as step S501, the measured signal strength signal intensity of system and matching measurement value (as by
The signal of test system output) and source signal value (such as test signal), judge signal by comparison
Whether intensity balances？(step S503), can introduce thresholding especially as criterion, if judging not
Balance (no), it is clear that have the interference that hardware or test environment cause, therefore can perform hardware adjustment,
Such as step S505.Step S501, repeatedly matching measurement value and source will be continued back at through the system of adjustment
Signal value, as the basis of hardware adjustment.
After hardware adjustment completes, step continues such as S507, and system will be sentenced by comparison specific sample signal
Disconnected signal strength signal intensity measured by each tester table is the most consistent？If variant, and difference is excessive through judging
And need to adjust, i.e. step S509, allow the test result between different test environment by adjusting pad value
Reach unanimity, could obtain correctly and in consistent substandard test result.By above-mentioned hardware adjustment (step
Rapid S505) adjust (step S509), to set up another test system, such as step S511 with pad value.
