Brief description of the drawings
Fig. 1 is that the structure of noiseless emitting and receiving equipment test macro forms block diagram.
Fig. 2 is the structural principle block diagram of noiseless emitting and receiving equipment test macro.
Detailed description of the invention
According to Fig. 1, the structure of noiseless emitting and receiving equipment test macro by launching shielded box, range attenuation part, receive shielded box, test result analysis four major parts form.
According to Fig. 2, the transmitting shielded box in noiseless emitting and receiving equipment test macro and reception shielded box built-in device fixture, coupled antenna, possess mechanical opening device, input/output interface on casing; Two shielded boxes are connected by attenuator, and the deviation of the input of data comparative analysis instrument analytical standard signal and measured signal, shows test results.
System, by transmitting shielded box, reception shielded box, attenuator, test result analysis part, has been set up a complete noiseless test space, can amplify certain distance by requirement simulation by decay part, meets test.
The concrete course of work is: the equipment fixture of the transmitter of access standard audio signal being put into transmitting shielded box, set in advance the operating distance of attenuator, open transmitting work, under shielded box closure state, signal connects audio output interface by modes such as wired grafting or wireless coupling, then by attenuator, space length is carried out to analog attenuation; Simultaneously, tested receiving equipment is put into the equipment fixture that receives shielded box, audio signal after decay is connected to tested receiving equipment by the input interface that receives shielded box, again by audio output interface output audio signal, transfer audio signal to the signal of telecommunication by acoustoelectric signal sensor, finally by data comparative analysis instrument, the working signal of tested receiving equipment and standard input signal are compared to analysis, show result, if in legitimate skew, test result is qualified, and the larger demonstration of deviation is defective.
In order to improve testing efficiency, by the control interface that receives shielded box, selectively connect more than 10 receiving equipment, reach and open primary shielding case by external control, test respectively the object of more than 10 equipment, avoided the damage of the frequent switch of shielded box, also improved testing efficiency.
Equally, transmitting shielded box is 10 above transmitters of alternative connection also, select different emission sources, by the deviation of test result analysis emission source by external control.
This system can be built many covers at detection line simultaneously, and can use simultaneously, and test environment is fixed, emission source is fixed, and has reduced other interference in test process, has ensured the accuracy of test result.
