Module, the centre frequency of the working frequency range in its low pass road is 2.412GHz, and the centre frequency of the working frequency range of middle passage is
2.437GHz, the centre frequency of the working frequency range of high channel is 2.462GHz.If when it is implemented, it can control above-mentioned dry plate wireless
Module carries out the transmitting of wireless signal on basic, normal, high three passages respectively, while controls the golden machine of test on the same channel
The reception of wireless signal is carried out, thus respectively obtains the system loss value of basic, normal, high three passages；Refer to subsequently carrying out radio frequency
When target is tested, any passage can be selected and taken place frequently surely with the centre frequency of the passage and penetrate wireless signal, and use measured in advance
Selected passage on system loss value carry out RF index calculating (when such as with low channel emission wireless signal, then using low
System loss value corresponding to passage calculates RF index), it is hereby achieved that the RF index result of respective channel.
Further, after step S31, can also include：Whether the actual emission power that judgement is calculated
In default power interval；If so, then the actual emission power is write into the memory of the module to be measured.
, can also be according to the actual emission power to module to be measured after the actual emission power of module to be measured is calculated
Carry out the calibration of power.Specifically, whether the actual emission power that RF index test equipment judges to be calculated is in default
Power interval, if so, then directly writing the actual emission power into the memory of module to be measured, complete the calibration of power；If
It is no, then readjust module power settings to be measured and control module to be measured to be taken place frequently surely according to the transmission power after adjustment and penetrate wirelessly
Signal, until the actual emission power being calculated falls in default power interval, wherein, the tune of module power settings to be measured
Haveing suffered journey is：As current transmission power is less than normal, then increase module power configuration value to be measured, as current transmission power is bigger than normal, then subtract
Small module power configuration value to be measured.
Calibration test, and calibration test knot are carried out to the signal transmission power of module to be measured by the above-mentioned means, realizing
Fruit is more reliable.
