Abstract
The utility model relates to the field of RF test technology, in particular to a rear environment simulated RF test tool. The RF test tool is characterized by comprising a test box, a product positioning groove, a terminal measuring head, test racks, an absorbing material and a tray, wherein the multiple edges of the test box are composed of the test racks, the internal and external surfaces of the test box are covered by the absorbing material, the tray is mounted in the test box, the product positioning groove is arranged at the top center of the test box, and the terminal measuring head is arranged at one side of the product positioning groove. The rear environment simulated RF test tool has the advantages that 1) the testing performance is highly consistent, a product tested in the environment is not influenced by the outside, and the test tool can be applied to testing different similar products; and 2) the precision can be higher, and due to elimination of interference of external electromagnetic signals, the testing frequency can be within a relatively narrow range, and the voltage standing wave ratio can be about 1.0.
Description
[technical field]
The utility model relates to RF technical field of measurement and test, specifically a kind of RF measurement jig of Reality simulation environment.
[background technology]
RF is the abbreviation of Radio Frequency, and expression can be radiated the electromagnetic frequency in space, and frequency range is between 300KHz～30GHz.RF radio frequency is radio-frequency current, is that a kind of high-frequency ac changes electromagnetic wave, and variation per second is less than the alternating current of 1000 times and is called low-frequency current, is greater than the high-frequency current that is called of 10000 times.In the processing and assembling of antenna, one very crucial technique is that the RF of product is tested at present; But at present RF test be all carry out in unlimited space and to band limits be also larger, be not only subject to the impact of external environment in unlimited space test, but also be subject to the interference of outer signals, can affect to the overall frequency range of product.
[summary of the invention]
The purpose of this utility model is to overcome the interference problem that existing RF test exists, a kind of tool that can Reality simulation environment, carry out RF test under dark room conditions is provided, its test number is comparatively fixing and accurate, has very high reference value for debugging and the judgement of subsequent product.
For achieving the above object, design a kind of RF measurement jig of Reality simulation environment, it is characterized in that: described RF measurement jig forms by testing casing, product orientation groove, terminal measuring head, testing jig, absorbing material and launcher, the object of setting up of test casing is in order to form a simulation darkroom environment, some ribs of this test casing are made up of testing jig, and some inside/outsides surface of described test casing is covered by absorbing material; Absorbing material can effectively stop the interference of external electromagnetic and other signals, can effectively stop like this because outer signals affect the RF causing to be offset, and more can effectively stop outer signals to enter and impact on product antenna performance.In above-mentioned test casing, launcher is installed, is provided with product orientation groove in the center of top of test casing, the other terminal measuring head that is provided with of side of described product orientation groove.
The top of described test casing is provided with grounded antenna, makes to test box house and forms space, airtight darkroom, and the signal testing out is like this more accurate.
The central authorities of described product orientation groove are provided with through hole, the center conllinear of described through hole and launcher.
Described through hole connects the duct to downward-extension, and described duct extends in test casing.
Described terminal measuring head adopts the L font standing upside down, and the crest line of described terminal measuring head is provided with slide rail, embeds the cable of fixing product to be measured on described slide rail.
Compared with prior art, the utlity model has following advantage:
One, test performance high conformity: product is tested in such environment, and consistance can be very little, is not subject to external influence in addition yet; Can try out the test in various similar products.
Two, precision can be better: because got rid of the interference of external electromagnetic signal, therefore the frequency range of test can be placed in narrow scope, and voltage standing wave ratio (VSWR) (VSWR=Voltage Standing Wave Ratio) can meet 1.0 left and right completely.
[brief description of the drawings]
Fig. 1 is the stereographic map of the utility model measurement jig;
Fig. 2 is the vertical view of the utility model measurement jig;
1. product orientation grooves in figure; 2. terminal measuring head; 3. testing jig; 4. absorbing material; 5. launcher.
[embodiment]
In conjunction with the drawings and the specific embodiments the technical solution of the utility model is further elaborated now, the structure of believing this device is clearly for a person skilled in the art.
The RF measurement jig of Reality simulation environment as shown in Figure 1, is made up of test casing, product orientation groove 1, terminal measuring head 2, testing jig 3, absorbing material 4 and launcher 5,
First, test casing is to be built into cube structure by 12 testing jigs 3, and testing jig 3 is as some ribs of square; Then cover above-mentioned square test casing with absorbing material 4, all inside/outsides surface of testing casing is covered by absorbing material 4;
Secondly, launcher 5 is arranged on the bottom surface central authorities of test box house, and object is in order to transmit in the product orientation groove to top.
Then, in the center of top of test casing, product orientation groove 1 is installed, the central authorities of product orientation groove 1 have through hole, the center conllinear of the center of this through hole and launcher 5.And the lower surface of through hole is connected and fixed to a duct to downward-extension, duct is extended in test casing.
Then, at the other terminal measuring head 2 of fixing a handstand L font of side of product orientation groove 1, as shown in Figure 2, on the crest line of described terminal measuring head 2, slide rail is installed, this slide rail is for embedding the cable of fixing product to be measured.
Finally, be provided with grounded antenna at the top of test casing, make to test box house and form space, airtight darkroom.
Its principle of work:
Product to be measured is put into product orientation groove 1, and cable is fixed on above the slide rail of terminal measuring head 2, and the different cables of different product can complete measurement like this.What form at testing jig 3, absorbing material 4 approaches in the same test casing in darkroom, by the launcher 5 of putting into, simulates under a three-dimensional test environment, carries out RF test.
