Embodiment one
Fig. 2 is a kind of flow chart for EMC quasi-peak values method of testing that the embodiment of the present invention one is provided.This method can be by
EMC quasi-peak values test device is performed, and the device can realize by the mode of software and/or hardware.As shown in Fig. 2 the party
Method specifically includes following steps：
Step 110, scanning obtain the full rate section of antenna radiation signal when preset height and turntable are in predetermined angle
In the corresponding initial spike of each Frequency point.
Wherein, EMC (electromagnetic compatibility) be to electronic product in terms of electromagnetic field EMI (Electromagnetic
Interference, electromagnetic interference) and EMS (Electro Magnetic Susceptibility, electromagnetism interference) ability
Comprehensive Assessment, is one of most important index of Quality of electronic products.What the embodiment of the present invention was mainly tested is electronic product to week
The electromagnetic interference capability in collarette border.
The test of electromagnetic compatibility is made up of test site and test equipment.Exemplary, test site can be standard EMC
Screened room (semi-anechoic chamber) (3 meters of fields or 10 meters of fields), or open area test site (3 meters of fields or 10 meters of fields).Exemplary, test
Equipment may include：Turntable, antenna, receiver, standard testing table, controller, computer and auxiliary software etc..
When carrying out EMC tests, equipment under test is positioned over testboard center, the test benchmark point and equipment under test of antenna
The horizontal range of imaginary radiation center (generally geometric center) be set to 3 meters, for receiving the radiation that equipment under test is sent
Signal is simultaneously sent in receiver by cable.Before testing, Test Engineer needs to switch on power, and adjusts test equipment
Working condition and the shield door for closing semi-anechoic chamber.
After the completion of the preparation of early stage, test can be proceeded by.Start test software getting Test Engineer
Instruction after, test software will start peak value scan pattern.By controller antenna can be arranged on preset height for 1 meter, 2
The position of rice, 3 meters and 4 meters.Specifically, when antenna is located at 1 meter of height, 360 degree of turntable forward or reverse；When antenna is located at 2
During meter Gao Du, turntable is inverted or positive three-sixth turn on the basis of the above-mentioned anglec of rotation.It should be noted that in order to ensure turntable
Normal rotation, after turntable positive three-sixth turn for the first time, anti-three-sixth turn is needed during secondary rotation.By that analogy, antenna is worked as
When being located at above-mentioned 4 preset heights respectively, turntable needs to rotate 4 times by different directions.After the completion of said process, it can get
Each Frequency point is when above-mentioned 4 different antennaes height and turntable are in above-mentioned 4 different angles in radiation signal full frequency band
Peak value simultaneously forms oscillogram.Then the maximum peak of each Frequency point can be got from the corresponding different peak values of each Frequency point
Value is used as initial spike.It is preferred that, the scope of full frequency band is 30M~1G hertz.
Step 120, target frequency point confirmed in each Frequency point according to initial spike.
Wherein, target frequency point is that peak value exceedes or close to the dispute point of default threshold value.Due to target frequency point
Amount of radiation may or already exceed default standard, have the risk caused harm to user, it is therefore desirable to target frequency point
Peak value verified.
Exemplary, the acquisition of target frequency point can be obtained by the way that initial spike is made comparisons with default threshold peak
The Frequency point that initial spike is more than threshold peak is used as target frequency point.Wherein, default threshold peak is the peak that regulation is limited
Value or the peak value set by intra-company.For example, at 300M hertz, if the peak value (amount of radiation) set by regulation be less than
46dB, and when currently the peak value of a certain Frequency point is 47dB, then the current Frequency point is target frequency point.Or present frequency point
When peak value is 45dB, now present peak value can be 45dB there is also the possibility of amount of radiation over range, therefore also by the Frequency point
Frequency point be used as target frequency point.Above-mentioned target frequency point, which is set, to be advantageous in that：On the basis of default threshold peak,
Satisfactory Frequency point in radiation signal each Frequency point can be excluded, and by the target of amount of radiation exceeded (or may be exceeded)
Frequency point is screened, and data basis is provided for the test of next step quasi-peak value.In the test of next step quasi-peak value, due to being not required to
All Frequency points are tested, can make it that the test of quasi-peak value is more targeted, while reaching the effect for reducing amount of calculation.
Step 130, the initial spike for keeping target frequency point, scanning confirm the corresponding object height of initial spike and target
Angle.
For same frequency point, the amount of radiation received by receiver in real-time change, the height of antenna and turntable
Influence of the angle to amount of radiation is all larger, therefore, in order to obtain an accurate Frequency point, it is necessary to obtain the first of target frequency point
All initial spikes are simultaneously always maintained at by beginning peak value.Now, in order that obtaining target frequency point can completely show, it can pass through to obtain and survey
The instruction of engineer's regulating frequency scope is tried, the frequency range of receiver is reduced, so operation can also increase frequency and show
Resolution ratio.If for example, target frequency point appears in 32M hertz, then by the way that frequency range is narrowed down into 30M~34M hertz
When, targetedly frequency can be tested again for the point of 32M hertz and its surrounding is with the size for judging its quasi-peak value
It is no to meet standard, while the accuracy of test can also be improved.
Due to occurring during the initial spike, the height and position of antenna is not necessarily in the integer height as described in step 110
Degree, meanwhile, the anglec of rotation of turntable is also not necessarily 0 degree or 360 degree.Accordingly, it would be desirable on the basis of the initial spike is kept,
There is the object height and angle on target corresponding to the Frequency point of the initial spike in acquisition.Wherein, it is determined that during object height,
Turntable can be fixed at an arbitrary position, and it is determined that during angle on target, then needing the position of antenna being maintained at object height.Pass through
The determination of object height and angle on target can solve the mistake caused in the prior art due to the test in antenna integer height
Difference.
Step 140, combining target height quasi- peak corresponding with angle on target acquisition precise frequency point and precise frequency point
Value.
It is determined that after object height and angle on target, receiver can be labeled to object height and angle on target.So
After the instruction for triggering receiver " Peak functions " by obtaining Test Engineer afterwards, it can get in object height and target angle
Precise frequency point under degree, and the corresponding quasi-peak value of precise frequency point can be shown by receiver.
It should be noted that if target frequency point more than one, needs to test each target frequency point, and
It is determined that the corresponding object height of each target frequency point and angle on target, can be by undesirable target frequency after test
Rate point is handled, to lift the security of product.

The corresponding initial spike of Frequency point, when there is the initial spike by scanning confirmation, object height and turntable where antenna
The angle on target at place, and object height and angle on target are combined can get precise frequency point, for precise frequency
Point obtains the corresponding quasi-peak value of point.Solve and only carry out EMC tests in the case where antenna is located at integer height and position in the prior art
Caused error so that the test result of EMC quasi-peak values is more accurate, the reliability of lifting quasi-peak value test.

Content described in above-described embodiment allows target frequency point completely to show, it is necessary to which the frequency range of receiver is reduced.Together
When need by the peak holding of each target frequency point in initial spike.Then turntable is fixed at an arbitrary position, and controls antenna
Risen to from 1 meter 4 meters (or dropping to 1 meter from 4 meters).In the process, when there is current goal Frequency point initial spike in record
The elevation information of antenna is object height.Above-mentioned setting is advantageous in that, there may be for test and radiates exceeded current mesh
When marking Frequency point, because the scanning range of antenna is standard when this scope is except being integer including antenna height from 1 meter to 4 meters
Quasi-peak value when peak value can also test antenna height for non-integer, solves and only quasi-peak value is entered when antenna is located at integer height
The present situation of row test, improves power of the test.After the object height of antenna is got, controllable antenna is maintained at above-mentioned target position
Put to carry out the test of next step.
Step 240, in object height, scanning obtains turntable and rotated a circle, the corresponding mesh of initial spike of target frequency point
Mark angle.
Wherein, angle on target is in test process, the turntable during initial spike that peak value is current goal Frequency point occur
Angle.It should be noted that, it is necessary to the position of antenna is set into object height, while controlling turntable in test process
Rotate a circle, target angle information can be got in rotary course.The setting of angle on target can be avoided only at 0 degree or 360 degree
The situation of Shi Jinhang quasi-peak values test, improves the accuracy of test.
Step 250, combining target height quasi- peak corresponding with angle on target acquisition precise frequency point and precise frequency point
Value.
Step 260, quasi-peak value is verified, and show quasi-peak value.
, it is necessary to which receiver is adjusted to spectrum analysis pattern by Test Engineer before being verified to quasi-peak value.Wherein, it is right
The mode that quasi-peak value is verified can be by the way of described in above-mentioned steps 230 and step 240, and here is omitted.It is logical
