Abstract

The present invention provides a device for realizing passive device testing. The device comprises a signal source module for generating one or more paths of source signals for testing which satisfy a preset condition, a combiner module which is connected to the signal source module and is used for combining the source signals for testing when the source signals for testing are in multiple paths, a duplex module which is connected to the combiner module and is used for transmitting one path of source signal for testing or the combined signal to a tested passive device and receives a reflection signal for testing reflected by the tested passive device and a direct connection signal for testing transmitted by the tested passive device, and a receiving module which is connected to the duplex module and is used for selecting receives signal according to an intermodulation test or power capacity test classifications and carrying out measurement and analysis to obtain a test result, wherein the source signals for testing are source signals for the intermodulation test or the source signals for the power capacity test, the direct connection signal for the intermodulation test and the direct connection signal for a power test of the direct connection signal for testing are transmitted through different ports.

Description

technical field [0001] The invention relates to the wireless field, in particular to a device for realizing passive component testing. Background technique [0002] With the increase of mobile communication network capacity, passive devices become more and more important as an important part of the network. The quality of passive device performance directly affects the network quality of the entire mobile distribution system. The performance index of the device becomes very necessary. Among the performance indicators of passive devices, intermodulation indicators and power capacity are two very important technical indicators. [0003] In the existing test scheme, the intermodulation index is tested by passive intermodulation test system or passive intermodulation tester; the power capacity is tested by power capacity test system, or test instruments and passive devices are used to build a test environment carry out testing. At present, there is no testing device that can ...
