Position to be detected, could be detected accordingly.It should be noted that for a high frequency cable, it is corresponding to be detected
Position can be one, there may also be more, depending on actual application demand.
Step S20 is detected the position to be detected, and obtained detected value and preset standard value are carried out
Comparison, to obtain comparing result.
In the present embodiment, behind the position to be detected on determining targeted high frequency cable, treats test position and carry out accordingly
Detection, to obtain the corresponding detected value in position to be detected, finally compares obtained detected value and preset standard value,
To obtain comparing result.Specifically, at the position to be detected on targeted high frequency cable is determined, the detection of detection device is controlled
Probe is fixed on position to be detected, is then detected with according to obtained detected value.Inspection is previously stored in detection device
It surveys standard value to compare detected value and preset standard value when detection obtains corresponding detected value, specifically carry out big
Small comparison, to determine the magnitude relationship detected between obtained detected value and standard value, and then according to obtained the two it
Between magnitude relationship determine whether the volume performance of targeted high frequency cable qualified.

Detection probe moved on targeted high frequency cable, when completing detection in the first position to be detected, control detection device
Detection probe be moved to next position to be detected and be detected, and so on until completing inspection to all positions to be detected
It surveys.
Step S30 is based on the comparing result, determines the performance of the targeted high frequency cable.
In the present embodiment, the detected value of position to be detected is obtained by detecting, and is compared to obtain corresponding comparison knot
When fruit, the performance of targeted high frequency cable is determined according to obtained comparing result, wherein performance is broadly divided into qualification and does not conform to
Lattice.Specifically, it is the comparison that will be detected obtained detected value and carry out size with preset standard value, with mesh when being compared
Position to be detected, when detected value is less than or equal to standard value, determines targeted high frequency cable only there are one on graticule cable
Performance is qualification；When detected value is more than standard value, determine that the performance of targeted high frequency cable is unqualified.
It should be noted that in the present embodiment, with a kind of absolute magnitude relationship judge high frequency cable performance whether
Qualification, but in actual production and detection process, due to the presence of error so that if current detected value is more than standard
Value, but poor very little between the two, almost within error range, it is also possible to be the cable of qualification, similarly, if currently
Detected value laugh in standard value, but poor very little between the two, corresponding cable is it could also be possible that underproof line at this time
Cable.However in actual production and detection process, due to can not absolute guarantee do not have the influence of extraneous factor, thus
It is inevitable for the appearance of error in actual detection process, in the present embodiment, sentence optionally with absolute size
Disconnected mode determines whether the performance of high frequency cable is qualified.
Further, can also include after the step of performance of targeted high frequency cable is determined：
Step a sends out corresponding prompt message based on the performance of the targeted high frequency cable, and preserves the target
The performance test results of high frequency cable.
Specifically, when being detected, for needing to ensure the institutes such as its length, parameter specification with a batch of high frequency cable
Some data informations are consistent, that is, the high frequency cable produced in the same way, and length must be also consistent.
In the present embodiment, when the performance of targeted high frequency cable is determined, can according to detect judge send out corresponding feedback
Prompt message, while the performance test results of targeted high frequency cable are preserved, wherein performance test results include at least each to be detected
The detected value of position, each position to be detected detected value comparing result and targeted high frequency cable performance whether qualification etc..
Specifically, when being fed back, when the performance of targeted high frequency cable is unqualified, it can send out and represent underproof carry accordingly
Show information or prompt tone, can also show testing result on the display interface of test side (detection device).
In the present embodiment, when the performance to targeted high frequency cable is detected, it is first determined on targeted high frequency cable
Position to be detected, then detected accordingly on position to be detected, so will detect obtained detected value in advance
The standard value set is compared, and is finally based on obtained comparing result and is determined whether the performance of targeted high frequency cable closes
Lattice.By prestoring the corresponding examination criteria value of targeted high frequency cable, after being detected, by detected value and standard value into
Row compares, and finally determines whether the performance of targeted high frequency cable is qualified by magnitude relationship between the two, and for same
The high frequency cable of batch can be detected in the same fashion, be realized in the EMC performance onlines progress to high frequency cable
It when detection, is detected, can online be examined with the EMC performances to high frequency cable of rapid batch by way of near-field detection
It surveys.
Further, it in step S10, determines the position to be detected of targeted high frequency cable, further includes before：
Step b receives and preserves the parameter information of inputted targeted high frequency cable, wherein the parameter information at least wraps
Include preset standard value and number of positions to be detected.
When being detected, due to it needs to be determined that position to be detected on targeted high frequency cable and ginseng when being compared
Value (standard value) is examined, therefore before being detected, it is thus necessary to determine that the quantity of position to be detected and inspection on targeted high frequency cable
Standard value is surveyed, and then can be quickly and accurately detected.
In the present embodiment, before being detected, receives and preserve the parameter corresponding to inputted targeted high frequency cable
Information, wherein parameter information include at least preset examination criteria value and number of positions to be detected.Specifically, it is detected it
Before, for a batch of high frequency cable, in certain allowable range of error, corresponding examination criteria value is consistent,
In order to enable examination criteria value is more accurate, typically by randomly choosing several high frequency cables, conventional far field is utilized
The method of test (anechoic chamber, test) is tested, with the corresponding examination criteria value of determination.For to be detected on high frequency cable
The quantity of position is also when carry out standard determines with determining, is mainly determined according to actual demand required to be checked
The quantity that location is set.
It should be pointed out that the quantity of position to be detected can only be determined by the method for remote testing, and for be detected
Specific location of the position on high frequency cable can not determine, tester is needed voluntarily to be sought when testing
Look for determination.Equally, " the step a " in " the step b " in the present embodiment and previous embodiment be without any contact, is used only for pair
The name of different step.
Further, after receiving and saving the relevant parameter information of inputted targeted high frequency cable, step S10
Include in detail：
The signal value of each position on targeted high frequency cable is detected, and obtains the maximum of signal value in a detection cycle
Point sets the corresponding position of the maximum point to position to be detected.
In actual detection process, when test position difference, obtained testing result has prodigious difference and not
Together, it detects for convenience and comparison judges, in the present embodiment, there is different methods of determination for the determination of position to be detected,
In specifically test process, the determination of position to be detected, the wherein determination of specific location can be carried out by spectrum analyzer
It is to be primarily due to by the way of wave crest detection, when being shown on spectrum analyzer, can quickly and accurately determine wave
The position of wave crest/trough of shape, that is, extreme point position, and for going out the other positions except wave crest/trough, although can be with
It obtains corresponding signal value well, but is can have prodigious trouble in physical location determination, and then in the present embodiment,
Preferably equally minimum position can also be used as position to be detected as position to be detected using maximum position.
It is each on targeted high frequency cable by detecting when determining the position to be detected of targeted high frequency cable in the present embodiment
The signal value of a position, then the highest place of selection signal value is as position to be detected, wherein position to be detected is not true
Place on real position refers specifically to signal peak place, and in actual transmission process, the highest place of signal is not
Only one, it is only necessary to select one of position as position to be detected, referring in particular to Fig. 4, as shown in figure 4, one
When the high frequency cable of measured length carries out high-speed digital signal transmission, the signal peak of a certain transmitted waveform there are multiple, than
Such as, there are tetra- positions A1, A2, A3, A4 in the highest position of signal, that is, this four positions can be used as position to be detected, by
It is generally similar in the testing result of each position, thus only need to select one of position as position to be detected i.e.
Can, while when determining position to be detected, determining the examination criteria value of position to be detected, specifically examination criteria value can be
The value of electrical signals of " wave crest " position, wherein value of electrical signals can be voltage signal values or current signal value, concrete foundation load
The characteristic properties of equipment, wherein when load equipment need to export be voltage signal when, the examination criteria value of setting will be electricity
Press signal value；When load equipment need export be current signal when, the examination criteria value of setting will be current signal value.
In addition, when there are multiple positions to be detected, it is commonly referred to as the wave that spectrum analyzer repeated detection is detected
The type of shape is different.As shown in figure 5, when the position to be detected of required detection there are two when, corresponding location to be checked
Respectively B1, B2, B3, B4 and C1, C2, C3, C4, C5, C6, C7, C8 are set, wherein B1, B2, B3, B4 belongs to first kind waveform
Position to be detected, C1, C2, C3, C4, C5, C6, C7, C8 are the position to be detected of the second class waveform, it is generally the case that different
It is different when the location of " wave crest " of the harmonic wave of type, and then corresponding position on high frequency cable is also different
's.It should be pointed out that in actual detection process, it is only necessary to select one of those " wave crest " point institute on high frequency cable
Corresponding position is used as band test position, does not need to be detected all " wave crest " positions in same rahmonic.
Further, it is the refinement flow diagram of step S20 in Fig. 2 with reference to Fig. 6, Fig. 6.
Step S201 is detected each position to be detected, to obtain corresponding detected value；
Step S202 obtains preset examination criteria value group, and judges that each detected value is marked with corresponding detection respectively
Size between quasi- value, to obtain the corresponding comparing result in each position to be detected.
In the present embodiment, at the position to be detected on targeted high frequency cable is determined, can treat test position into
The detected value examination criteria value corresponding with preset examination criteria value group that detection obtains, is then compared by row detection,
To determine magnitude relationship between the two.Specifically, when being detected, (electric by detecting the value of electrical signals of position to be detected
Press signal value or current signal value), the value of electrical signals for then obtaining detection and corresponding standard value of electrical signals (examination criteria
Value) it is compared, wherein by taking the value of electrical signals detected is voltage signal values as an example, if the current voltage being detected
Value is V1, and standard voltage value (examination criteria value) is V0, and in the process being compared, there is only two kinds of passes between V1 and V0
System, one of which are that V1 is less than or equal to V0, and the testing result of position to be detected is qualification at this time, and another kind is that V1 is more than V0, this
When at this time position to be detected testing result be it is unqualified.
Since the quantity for the position to be detected during atual detection, being detected can be multiple, therefore in determination
When whether the EMC performances of targeted high frequency cable are qualified, need to be carried out according to the testing result of all positions to be detected synthesis true
Fixed, in particular it is required that when the testing result in all positions to be detected is qualification, just determination detects to obtain high frequency cable
EMC performances be qualified.
Further, it is the refinement flow diagram of step S30 in Fig. 2 with reference to Fig. 7, Fig. 7.
Step S301 determines each position to be detected based on the corresponding comparing result in each position to be detected
Testing result.
Step S302 determines the property of the targeted high frequency cable based on the corresponding testing result in each position to be detected
Can whether qualified.
In the present embodiment, the detected value of each position to be detected is being obtained by detection, and determine by comparison and respectively wait for
Comparing result between the corresponding detected value of test position and corresponding standard detection value, then according to each position to be detected
Corresponding testing result determines whether the EMC performances of targeted high frequency cable are qualified.Specifically, it is examined in the performance of high frequency cable
When survey, need to ensure all signals can normal transmission, when determining the testing result of each position to be detected, by being examined
The type of the harmonic wave of survey is different so that obtained testing result is also not necessarily identical, that is, the detection knot for the position to be detected having
Fruit is and qualified, and the testing result for the position to be detected having is unqualified, however when actual performance judges, it needs to own
The testing result of position to be detected be qualified.
Specifically, when whether the testing result for determining each position to be detected qualified, value of electrical signals that detection is obtained with
Corresponding standard value of electrical signals (examination criteria value) carries out the comparison of size, and obtained telecommunications is detected when position to be detected is corresponding
Number value be less than or equal to standard value of electrical signals when, determine this position to be detected testing result be qualification, when position pair to be detected
When the value of electrical signals that the detection answered obtains is more than standard value of electrical signals, determine that the testing result of this position to be detected is unqualified.
Obviously when being detected, judge whether it is qualified only need by monitoring to detected value be compared with examination criteria value, root
It is determined according to magnitude relationship between the two, but for the performance detection of targeted high frequency cable, then needs according to institute
The testing result for the position to be detected having is determined, and specifically method of determination is：When the testing result of all positions to be detected
When being qualification, the EMC performances of target cable are qualification；When being waited in all positions to be detected there are testing result is underproof
When test position, the EMC performances of target cable are unqualified.Namely only when the testing result of all positions to be detected is equal
When qualified, the performance of this high frequency cable is only qualification.
It should be noted that in the present embodiment, to the performance of high frequency cable judge only to have done whether qualified judgement,
But during the use of actual high frequency cable, (whether signified performance refers to not only qualified to different performance herein, also
To qualified with one grade classification of underproof high frequency cable progress) the equipment that is suitble to of high frequency cable would also vary from,
Therefore when being detected, in addition to that whether other than qualification, can also be carried out to high frequency cable etc. in the performance for judging high frequency cable
Grade divides, that is, high frequency cable performance other than whether qualified, the grade height of performance is can also be, below with only
It is illustrated for one position to be detected, wherein detected value indicates that examination criteria value is indicated with V0, is specifically divided with V1
Situation can be as shown in table 1：
Table 1
| V1-V0 | (- ∞)~-5 | - 5~-2 | - 2~0 | 0 | 0~2 | 2~(+∞) |
| Grade | T3 | T2 | T1 | T0 | T4 | T5 |
It is detected treating test position, when obtaining detected value, by carrying out pair detected value and examination criteria value
Than the two optionally being carried out mathematic interpolation in the present embodiment, to obtain result of calculation, as shown in table 1, for different
Result of calculation is corresponding with different class informations, and specifically class information includes：T3 be excellent, T2 be good, T1 be qualified, T0 is
In, T4 be unqualified and T5 be it is abnormal, it is certain due to that can exist in the production of high frequency cable and performance testing process

In the present embodiment, preferably using " wave crest the detection method " (power namely by detecting the electric signal at wave crest --- electricity
Pressure signal or current signal size) come determine detected high frequency cable performance quality, therefore, although in a high frequency
One kind position to be detected on cable only there are one, but actual position to be detected have it is multiple, specifically as shown in figure 4, waveform
" wave crest " position have 4, respectively A1, A2, A3, A4, but belong to same class, that is, performances are carried out in this 4 positions
When detection judges, in certain allowable range of error, testing result is the same.At this time by mobile detection probe in high frequency
It is moved on cable, by finding signal strength highest or minimum position, you can find corresponding position to be detected.
Likewise, working as testing result of the detected high frequency cable needs according to multiple types transmitted waveform, to determine
When the performance quality of the high frequency cable of detection, it is assumed that currently need the detection using two different transmitted waveforms to be sentenced
Disconnected, the position distribution for the position to be detected on high frequency cable detected at this time is as shown in figure 5, in particular it is required that be detected
Position be divided into two classes, a kind of position to be detected is B1, B2, B3, B4, another kind of position to be detected is C1, C2, C3, C4,
C5, C6, C7, C8, when being detected based on first kind transmitted waveform, by the position of mobile detection probe, in detection probe
When being moved to any one position in B1, B2, B3, B4, you can complete to detect as position to be detected, and work as and need to be based on second
When class transmitted waveform is detected, again by the position of mobile detection probe, when its be moved to C1, C2, C3, C4, C5,
In C6, C7, C8 when any one position, you can complete to detect as position to be detected.And then the performance quality in carrying out most
Really timing, is judged based on two class testing results.
It should be noted that needing sentencing for the performance quality based on a variety of different transmitted waveforms progress high frequency cables when existing
When disconnected, complete to detect by repeatedly moving detection probe.Further, the movement of detection probe can pass through mechanical device
