Abstract
The invention provides a clamping tool for an antenna test and a test method. The clamping tool comprises a seat body, a pressing device and at least two electric performance detection main boards and at least two sets of fixing devices. The design of the clamping tool enables tests for limit samples and samples to be tested to be performed synchronously. A threshold value obtained through testing the limit samples under a same state can be used for determining whether the sample to be tested is qualified or not. The clamping tool and the test method reduce the test and determination errors which are caused by fluctuation in stability of the test clamping tool to the maximum, and improve detection precision.

Background technology
At present, antenna production firm, when product export is checked, all can use the case detection of electrical property full procuratorial organ to produce
The electrical property of product.Specifically, survey according to element designs antennas such as the profile of product, line form, performances
Examination fixture, fixture is connected on test instrunment, is then placed on test fixture by product to be measured, and fixture is solid
Surely, after living product to be measured, test can be started.Before test, first a limit product is tested, with it
Test parameter is as test gate limit value.During test, test instrunment is connected with controlling computer, setup control computer
In threshold value, compare test result and threshold value to judge the whether the most satisfied requirement of dispatching from the factory of institute's survey properties of product.
Yet with machining accuracy, assembling tolerance, use the factors such as abrasion that the stability of test fixture can be caused to decline,
There is fluctuation in test data.As it is shown in figure 1, threshold range determined by limit sample test first is arrow
Shown in scope, product test result falls at A to A ' be then judged to certified products in interval, falling is outside interval
Defective work.After test fixture stability declines, test limits sample again, it is found that limit sample
Test value changes so that real threshold range becomes the interval of B to B '.But owing to threshold value sets
Will not often change after Ding, still can be judged as in A to B interval if the test result of testing sample falls
Certified products, falling then can be judged as defective work in A ' to B ' interval, the most real district
Between have been changed to actual should being judged as defective work of the interval product of B to B ', such A to B and close
Lattice product, product interval for A ' to B ' is actual should be judged as defective work for certified products.If so still
Using the threshold value that records at first as criterion, it may appear that test result judges inaccurate, waste is caused to be closed
Lattice product and the risk of outflow defective work.
Summary of the invention
The technical problem to be solved is: cause waste to be closed owing to antenna measurement fixture stability declines
