Second power of the second pilot signal of 1023MHz is -15dBm, the second power of the second pilot signal of 1024MHz be -
Second power of the second pilot signal of 18dBm, 1025MHz is -20dBm.
In step 303, based on the first power and the second power on above-mentioned each detection frequency point, monitoring module can determine
The practical index of each detection frequency point.Optionally, monitoring module can be determined according to the difference of the second power and the first power and be detected
The practical index of frequency point.
Such as each detection frequency point on bandwidth of operation：The practical index for detecting frequency point 1010MHz is -3dB, detects frequency point
The practical index of 1011MHz is -2.8dB, and the practical index of detection frequency point 1012MHz is -2.7dB, detection frequency point 1013MHz's
Practical index is -2.6dB, and the practical index of detection frequency point 1014MHz is -2.5dB, the practical index of detection frequency point 1015MHz
Practical index for -2.5dB, detection frequency point 1016MHz is -2.6dB, and the practical index of detection frequency point 1017MHz is -2.7dB,

The practical index of 1020MHz is -3dB.That is pass through leading for the filter on each detection frequency point on above-mentioned bandwidth of operation
The power of frequency signal is all decayed within 3dB.
Such as each detection frequency point in inoperative bandwidth：The practical index for detecting frequency point 1005MHz be -20dB,
The practical index of 1006MHz is -17dB, the practical index of 1007MHz is -15dB, the practical index of 1008MHz be -12dB,
The practical index of 1009MHz is -10dB, the practical index of 1021MHz is -10dB, the practical index of 1022MHz be -12dB,
The practical index of 1023MHz is -15dB, the practical index of 1024MHz is -18dB, the practical index of 1025MHz is -20dB.
That is the power in above-mentioned inoperative bandwidth on each detection frequency point by the pilot signal of the filter all decays and decays
Value is all at 10dB or more (including 10dB).
In a kind of optional embodiment, the detection frequency point on the bandwidth of operation that monitoring module determines filter and non-work
Before making the detection frequency point in bandwidth, it may be determined that the standard index of each detection frequency point, such as each inspection on bandwidth of operation
The standard index of frequency measurement point is that the standard index of each detection frequency point on -3dB, such as inoperative bandwidth is -15dB.Step
In 303, if the practical index of each detection frequency point and the difference of standard index on bandwidth of operation meet preset range, inoperative band
The practical index of each detection frequency point on width and the difference of standard index exceed preset range, then monitoring module can be to adjustable die
Block sends adjust instruction, which is used to indicate adjustable module and adjusts filter according to adjust instruction.
Optionally, which can be variable diodes, resistance, capacitance etc., and specifically, monitoring module can be adjusted
The voltage of the whole variable diodes, the voltage by changing variable diodes adjust filter.
Due in system monitoring module can by directly influencing the index of filter to the adjustment that adjustable module carries out,
Before step 301, i.e., before monitoring module sends test command to the signal generator, in a kind of optional embodiment,
Monitoring module can give one initial voltage of adjustable module, in a kind of optional embodiment.Monitoring module can be according to filtering
The standard index of device determines the initial voltage of adjustable module, and sends initialization directive to adjustable module according to the initial voltage,
Wherein, initialization directive is for adjusting the voltage of adjustable module to initial voltage.Since the initial voltage is according to filter
Standard index be calculated, i.e., the standard index of each detection frequency point on the bandwidth of operation of the example above is -3dB, than
If the standard index of each detection frequency point in inoperative bandwidth is -15dB, so the initial voltage obtained can be substantially close to
In the target voltage adjusted, in this way, the number of adjustable module voltage adjustment can be saved.
In a kind of optional embodiment, which includes an adjustable submodule, this is adjustable submodule can be with
It is varactor, if the difference of the standard index of practical index and detection frequency point is beyond in preset range, such as bandwidth of operation
The practical index of each detection frequency point and the difference of standard index meet preset range, each detection frequency point in inoperative bandwidth
Practical index and the difference of standard index exceed preset range.The monitoring module generates the first adjustment and instructs and be sent to adjustable submodule
Block.The first adjustment instruction is used to indicate adjustable submodule and adjusts the filter, such as the first adjustment according to the first adjustment instruction
Instruction is that the voltage of adjustable submodule is turned up 50 milliamperes.
Monitoring module continues the first power that pointing signal generator generates on each detection frequency point leads for the first of 0dBm
Frequency signal after filtered device processing, obtains the third pilot signal with third power on each detection frequency point.Monitoring module
The practical index of each detection frequency point is determined according to the difference of third power and the first power, if each detection frequency on bandwidth of operation
The practical index and the difference of standard index of point meet preset range, the practical index of each detection frequency point in inoperative bandwidth and
The difference of standard index also complies with preset range, then preserves the voltage of adjustable module, terminates flow.This means that filter and adjustment
Good adjustable module can reach necessary requirement, can come into operation.
If the practical index of each detection frequency point and the difference of standard index on bandwidth of operation meet preset range, inoperative
The practical index of each detection frequency point in bandwidth and the difference of standard index still exceed preset range, but are above preset range
Numerical value it is smaller, then monitoring module can generate second adjustment and instruct and be sent to the adjustable module, second adjustment instruction
