Abstract

An RF (Radio Frequency) line loss calibrating device comprises a computer and control software, a comprehensive test instrument, a testboard, a reference machine and a coaxial RF cable, wherein the computer and control software is connected with the comprehensive test instrument through the coaxial RF cable; and the comprehensive test instrument is connected with the testboard through the coaxial RF cable. The RF line loss calibrating device is characterized in that the reference machine is connected with the comprehensive test instrument through a welding RF cable. By adopting the RF line loss calibrating device, manual record is not needed, the whole process is controlled and completed by a computer, and the operation is convenient and fast; and data stored in a storage area can not be lost.

Description

A kind of radio frequency line loss calibrating installation
Technical field
The utility model relates to the RF calibration field, relates to a kind of radio frequency line loss calibrating installation in particular.
Background technology
Present electronic communication is highly developed, and mobile phone has become the indispensable electronic equipment of people's daily life.For the manufacturer of mobile phone, workmanship and production efficiency are the key factors that must consider, and many producers have all strengthened the link of RF calibration, and introduce the RF calibration system of automation.RF calibration is the most important link during mobile phone is produced.Country is stipulating detailed national standard to communication equipment aspect the radio-frequency (RF) index, so the accuracy of RF calibration has determined whether the radio-frequency performance of mobile phone meets the peremptory norm of country.The utility model has very big raising for the accuracy of the RF calibration of mobile phone production.In the mobile phone production process, RF calibration is made up of the Control Software of comprehensive tester, coaxial radio frequency cable, testboard and computer terminal.Cell base station in the comprehensive tester analog communication network is measured the radiofrequency signal of mobile phone emission, sets up to call out with mobile phone to be connected.The Control Software of computer terminal by the data-interface that comprehensive tester provides, is obtained the radio frequency parameter of its measurement; Data-interface by mobile phone provides writes parameter to mobile phone and controls its state.Coaxial radio frequency cable is used for connecting comprehensive tester and testboard, sets up the individual link of mobile phone and comprehensive tester.Because radiofrequency signal self is intrinsic, exists loss in transmission course.If this part loss does not have suitable method accurately to be measured, then the RF calibration that mobile phone is carried out is irrational, will cause the radio-frequency (RF) index of the mobile phone after the calibration can not satisfy code requirement.
In order to address this problem, the way that often adopts had following two kinds in the past.One: when buying coaxial radio frequency cable, allow manufacturer measure the line loss of coaxial radio frequency cable, and this value nominal thereon.When RF calibration, use line loss numerical value that this producer provides as standard of appraisal.This method is not considered the work on the spot environment, does not consider that actual physical connects situation yet, and experimental verification shows that this method exists than mistake; Two: selected normal mobile phone is as the reference machine, and one section radio frequency line of welding is connected to comprehensive tester on radio frequency testing point.Read with reference to acc power, record on the label, label is pasted on reference on the machine.When needs calculate the radio frequency line loss of certain testboard, only need this is placed on this testboard with reference to machine, read with reference to acc power once more by comprehensive tester, and the numeric ratio on label to be, its difference is line loss.There is inefficient shortcoming in this method, and owing to be recorded on the paper media (label), is difficult for preserving, and therefore this method and unreasonable wastes time and energy, and is unfavorable for producing in batches.
The utility model content
The shortcoming that exists when solving test line loss in the existing RF calibration, the utility model provide a kind of easy to operate, data to be easy to the line loss test of the RF calibration preserving, can not lose.
For this reason, the utility model is taked following technical scheme:
A kind of radio frequency line loss calibrating installation, include computer and Control Software, comprehensive tester, testboard, with reference to machine, coaxial radio frequency cable, described is the normal mobile phone that the data storage area is reserved with the User Defined zone with reference to machine, described normal mobile phone is provided with the described self defined area data write interface of visit, is connected with comprehensive tester by the welding radio frequency line with reference to machine.
Employing the utlity model has following advantage: 1, do not need manual record, process is finished by computer control fully, and is easy to operate and quick; 2, data are kept at the memory block, do not exist to lose phenomenon.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
With reference to Fig. 1, a kind of radio frequency line loss calibrating installation, include computer and Control Software 1, comprehensive tester 2, testboard 3, coaxial radio frequency cable 4, with reference to machine 5, described is the normal mobile phone that the data storage area is reserved with the User Defined zone with reference to machine, described normal mobile phone is provided with the described self defined area data write interface of visit, is connected with comprehensive tester by the welding radio frequency line with reference to machine.
Concrete test process is as follows:
Selected normal mobile phone is as the reference machine, and the User Defined zone is reserved in this data storage area with reference to machine, and the read-write interface of this area data of visit is provided; One section radio frequency line of welding is connected to comprehensive tester on the radio frequency testing point of reference machine, by the Control Software of computer, measures the magnitude of power with reference to machine, and Control Software writes data storage area with reference to machine to this numerical value; When testboard need calculate line loss, only need place the reference machine on this testboard, the Control Software of computer is measured magnitude of power, and this numerical value and with reference to the numeric ratio in the machine data memory block, difference is the line loss of this testboard.

Claims (2)
