Description
Technical field
This utility model relates to NFC technical field of radio frequency test, particularly relates to a kind of NFC radio system test system.
Background technology
The radio frequency testing technology of NFC is applied quite varied now, in security protection, the application of the industry such as logistics and retail is the most universal, owing to relevant standard is also in the middle of gradual perfection, each manufacturer is uneven at technological layer, this is accomplished by going into overdrive at measurement direction, present existing NFC test is main by the R&S RTO oscillograph of band option RTO-K11, it is equipped with the PC of FS-K112 application software for XRF analysis and coordinates interpolation R&S audiofrequency spectrometer to be connected with each other work together, R&S vector signal source with option K6 produces signal, although test event is the most comprehensive, but this test mode high cost and testing process is relatively complicated.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of simple and economical and practical NFC radio system test system.
Concrete scheme is as follows: a kind of NFC radio system test system, including: Agilent spectrum analyzer, Agilent E4438C series of digital signals source, computer and NFC device, described Agilent E4438C series of digital signals source and described NFC device wireless connections, described Agilent E4438C series of digital signals source sends a signal to described NFC device, described NFC device and described Agilent spectrum analyzer wireless connections, described NFC device sends a signal to described Agilent spectrum analyzer, described Agilent spectrum analyzer is connected by data wire with described computer.
Optional, described computer is desktop computer, portable computer or personal digital assistant.
Optional, described data wire is LAN mouth data wire, com port data wire or USB data line.
This utility model testing process is simple, and cost more mental retardation obtains more accurate test result compared to existing technology.
Accompanying drawing explanation
Fig. 1 is NFC system testing process and the equipment of embodiment 1；
Fig. 2 is NFC system testing process and the equipment of embodiment 2.
Detailed description of the invention
For further illustrating each embodiment, this utility model is provided with accompanying drawing.These accompanying drawings are a part for this utility model disclosure, and it is mainly in order to illustrate embodiment, and the associated description of description can be coordinated to explain the operation principles of embodiment.Coordinating with reference to these contents, those of ordinary skill in the art will be understood that other possible embodiments and advantage of the present utility model.In conjunction with the drawings and specific embodiments, this utility model is further illustrated.
nullEmbodiment 1: combine Fig. 1，Show flow process and equipment that the present embodiment NFC tests，Test for NFC device mainly includes both sides test，Including NFC active inquiry pattern and passively listen to pattern，Under active inquiry pattern: first use Agilent E4438C series of digital signals source to carry out input signal modulated excitation for NFC active inquiry pattern device，It is then passed through NFC device to export to Agilent spectrum analyzer，Test under the Trace-IQ Mode of Agilent spectrum analyzer，Notebook computer is attached by LAN mouth data wire and Agilent spectrum analyzer and signal is analyzed the waveform of output signal，Analyze the test parameter that postscript picture recording is corresponding，Including subcarrier frequency accuracy、Power measurement、Wave character is measured、Load modulation sensitivity and threshold value test，Provide outcome evaluation，And outcome evaluation and the index producing family's offer are carried out comparison，And export test report.
Flow process under passively listening to pattern is substantially similar with the test under active inquiry pattern, simply derived digital signal is passively listened to pattern device and is polled signal modulation input for NFC, and the parameter for test changes, the test parameter under passively listening to includes load modulation measurement, power receives test and frame delay time test.
Embodiment 2: combine Fig. 2, embodiment 2 is essentially identical with the equipment of embodiment 1 and flow process, difference is: use desktop computer to be attached with Agilent spectrum analyzer by com port RS_232 data wire, compared to the scheme described in embodiment 1, use LAN mouth data line transfer more stable, and use notes instinct to test more easily.
The person skilled of this area should appreciate that, in the middle of the present embodiment, computer is attached by LAN mouth data wire and com port data wire with spectrum analyzer, as an alternative, USB data line also can be used to be attached, any restriction is not done for the data wire type used.
Although specifically showing in conjunction with preferred embodiment and describing this utility model; but those skilled in the art should be understood that; in the spirit and scope of the present utility model limited without departing from appended claims; this utility model can be made a variety of changes in the form and details, be protection domain of the present utility model.
