In existing antenna industry, each tame practitioner can carry out relevant international standard, as ANSI, CISPER, EN etc., at electromagnetic compatibility (Electromagnetic Compatibility, EMC) measure the decay of normalization place (normalized site attenuation, NSA) value in the breadboard radiation anechoic chamber.
In the measurement operation of general normalization place pad value, all be phase place mid point and the marginal position of determining emitting antenna earlier in the mode of manually-operated weight, then employ minimum four amount examination personnel again and carry out range observation, to determine the predetermined space distance of receiving antenna and emitting antenna, and after the predetermined space distance of having determined receiving antenna and emitting antenna, receiving antenna can be set in view of the above.
Yet, determine definite mode of the phase place mid point and the marginal position of emitting antenna by the manually-operated weight, not only be easy to generate error, and easily emitting antenna itself impacted, and then make the precision deficiency of the follow-up normalization place pad value of measuring.In addition, minimum needs are employed the mode that four amount examination personnel can carry out range observation the beginning, except directly the electromagnetic compatibility laboratory being caused the too much human cost, also indirectly other predetermined experiment schedules of carrying out of electromagnetic compatibility laboratory have been caused influence.
Therefore, need to provide a kind of measurement operation that tool improves existing normalization place pad value of measuring really.
The utility model content
In view of the many disadvantages of prior art, fundamental purpose of the present utility model is to provide a kind of can measure the phase place mid point of emitting antenna and the measurement tool of marginal position exactly.
Another purpose of the present utility model is to provide a kind of measurement tool that too much human cost can be measured the predetermined space distance of receiving antenna and emitting antenna that need not drop into.
Reach other purposes in order to achieve the above object, the utility model provides a kind of measurement tool, is applied on the antenna assembly for the user, and this measurement tool comprises: first support bar; Second support bar is with the setting interlaced with each other of first support bar; And fixture, be arranged at an end of this first support bar, in order to should measure the tool fixed configurations on this antenna assembly.
In an example of the present utility model, also be provided with ruler spare on the other end of this first support bar, this ruler spare can be tape measure.And this first support bar and/or second support bar have the structure that can stretch freely with adjustment length.
In other words, the utility model provides a kind of measurement tool, is applied to comprise on the antenna assembly:
First support bar;
Second support bar is with the setting interlaced with each other of this first support bar; And
Fixture is arranged at an end of this first support bar, and should measure the tool fixed configurations on this antenna assembly.
In the described measurement tool of utility model, preferably, also comprise ruler spare, be arranged on this first support bar and the relative other end of an end that this fixture is set.
In the described measurement tool of utility model, preferably, this ruler spare is a tape measure.
In the described measurement tool of utility model, preferably, this second support bar is crisscross arranged with its geometric center point and this first support bar.
In the described measurement tool of utility model, preferably, the stagger angle of this first support bar and second support bar is 90 °.
In the described measurement tool of utility model, preferably, this fixture comprise collar unit and the locking unit, this collar unit is sheathed on this antenna assembly, and should the locking unit with this collar unit fixed configurations on this antenna assembly.
In the described measurement tool of utility model, preferably, this fixture is anchor clamps.
In the described measurement tool of utility model, preferably, this antenna assembly is an emitting antenna.
In the described measurement tool of utility model, preferably, this first support bar and/or this second support bar have the structure that can stretch freely with adjustment length.
Therefore, by first support bar, second support bar, and the mutual collocation of fixture, measurement tool of the present utility model is available for users to measure exactly the phase place mid point and the marginal position of emitting antenna, and behind the phase place mid point of measuring emitting antenna and marginal position, the utility model more can be by ruler spare easily, measure the predetermined space distance of receiving antenna and emitting antenna apace, so than prior art, the utility model not only is available for users to measure exactly normalization place pad value, also need not drop into too much human cost and operate.

Embodiment
Below by specific concrete example embodiment of the present utility model is described, those of ordinary skill in the art can understand other advantages of the present utility model and effect easily by the content that this instructions disclosed.Certainly, the utility model also can be implemented or be used by other different concrete examples.
See also Fig. 1 and Fig. 2, wherein, Fig. 1 is the structural drawing that illustrates measurement tool of the present utility model, and Fig. 2 illustrates the structure of measurement tool of the present utility model and uses synoptic diagram.
As shown in Figures 1 and 2, measuring tool 1 for example is on the antenna assembly of emitting antenna 2 for can be applicable to, and measurement tool 1 comprises first support bar 10, second support bar 11, fixture 12 and ruler spare 13.
During actual enforcement, the user can be sheathed on collar unit 120 earlier on the upright antenna holder 22 of emitting antenna 2, then adjust the length of first support bar 10 and second support bar 11, and adjust to measure the liftoff height of tool 1, can be to make first support bar 10 and second support bar 11 corresponding to the drop shadow spread of the side direction antenna holder 20 and the antenna lobe 21 of emitting antenna 2.And after adjustment was finished, the user can lock by the 121 pairs of collar unit 120 in locking unit, and then order measurement tool 1 can be fixed in emitting antenna 2.At this moment, the user can measure the phase place mid point and the marginal position of emitting antenna 2 exactly by first support bar 10 and second support bar 11, to replace traditional weight.And behind the phase place mid point of measuring emitting antenna 2 and marginal position, the user also can directly operate ruler spare 13 with a people power, and then measure the predetermined space distance of receiving antenna (not shown) and emitting antenna 2 quickly and easily, for example measure 30 meters predetermined space point by ruler spare 13, and with the set-point of this predetermined space point as receiving antenna, thereby carry out the process of measurement of follow-up normalization place pad value, and then accurately measure normalization place pad value.
What deserves to be mentioned is that according to different actual demands, the utility model optionally is not provided with aforesaid ruler spare 13.Consider the anchor clamps that fixture 12 also can be designed to be correlated with in order to tackle different costs.
In sum, because measurement tool of the present utility model comprises first support bar that can arrange in pairs or groups alternately, second support bar and fixture, so be available for users to measure exactly the phase place mid point and the marginal position of emitting antenna, and behind the phase place mid point of measuring emitting antenna and marginal position, measurement tool of the present utility model also can be by ruler spare for the user easily, measure the predetermined space distance of receiving antenna and emitting antenna apace, so than prior art, the utility model not only is available for users to accurately measure normalization place pad value, and does not need the too much human cost of input to operate.
