specific Embodiment approach 1

[0021] Specific implementation mode 1. Combination figure 1 Describe this specific embodiment, a system for testing the anti-jamming capability of ISM frequency band wireless communication products, which includes No. 1 adjustable attenuator 2, combiner 3, No. 2 adjustable attenuator 4, signal source 5 and receiver error Code characteristic testing equipment 7, the ISM frequency band wireless communication product to be tested includes a transmitter 1 and a receiver 6, the signal transmitting end of the transmitter 1 is connected to the signal receiving end of the No. 1 adjustable attenuator 2, and the No. 1 adjustable attenuator 2 The attenuated signal output end of the attenuation signal is connected with the first attenuation signal input end of the combiner 3; the signal transmitting end of the signal source 5 is connected with the signal receiving end of the second adjustable attenuator 4, and the attenuation signal of the second adjustable attenuator 4 The output end is ...

specific Embodiment approach 2

[0023] Specific embodiment two, based on the test method of the system of a kind of test ISM frequency band wireless communication product anti-jamming ability described in this specific embodiment one, it is realized by the following steps:

[0024] Step 1. Power up the transmitter 1, receiver 6, signal source 5 and receiver bit error characteristic test equipment 7 after debugging, and the transmitter 1 transmits the signal to the calibrated No. 1 adjustable attenuator 2. No. 2 adjustable attenuator 2 is attenuated and then input to combiner 3; the signal source 5 is used to transmit the system signals as described in Table 1 respectively, and the reference attenuation value of No. 2 adjustable attenuator 4 after calibration is adjusted. The code characteristic test equipment 7 observes the bit error situation of the receiver 6, and when the preset bit error rate range is reached, the adjustment of the No. 2 adjustable attenuator 4 is stopped, and the power sum of the useful ...

Abstract

The invention provides a system and method for testing antijamming capability of wireless communication products operating at ISM (Industry, Science and Medical) frequency range, which relates to the method and the method for testing antijamming capability of wireless communication products and solves the problem that the antijamming capability of wireless communication products operating at ISM frequency range can not be tested. The system works as follows: signals transmitted by a transmitter are input into a receiver after passing through a first adjustable attenuator and a first combiner;signals transmitted by a signal source are input into the receiver after passing through a second adjustable attenuator and a second combiner. The method comprises the steps of: simulating signals ofcommon radio communication systems near and in communication product working frequency bands through a signal source; and observing error code conditions of a receiver to be tested by adopting receiver error coder characteristic testing equipment to obtain a desired signal power and an interference signal power of each system and further realize quantitative analysis on the antijamming capabilityof the wireless communication products operating at ISM frequency range. The invention is applicable to testing the antijamming capability of the wireless communication products operating at ISM frequency range.

Description

technical field [0001] The invention relates to a system and a testing method for testing the anti-interference ability of wireless communication products. Background technique [0002] In order to reduce the mutual interference between different radio communication systems, the International Telecommunication Union has allocated corresponding frequency bands for each wireless communication system, and stipulated the power range of the transmitter and the spectrum template of the transmitted signal. However, the ISM frequency band is an exception. Since there is no authorization restriction, this frequency band is used by many short-distance communication products, so the mutual interference between these products and the interference of other frequency band radio communications to these products have become problems that cannot be ignored. The meaning of the mentioned ISM frequency band is the same in all countries, namely: 2.4GHz frequency band. [0003] A wireless commun...
