Abstract

The invention discloses a reliability test device and method, belonging to the technical field of radio frequency communication. The device has a plurality of radio frequency signal output ports, and a phase-locked loop circuit, a variable gain amplifier, a power amplifier and a gain compensation circuit are integrated in the device. While meeting the different requirements for frequency and power of different device pairs, it ensures the consistency of the signal of each RF output port. The power detection circuit in the device can monitor the RF output power of the test device in real time, and the monitoring results are displayed by LED lights. In the reliability test project that needs to add radio frequency signals, the test platform built by the reliability test device proposed in the present invention is simple. It only needs to provide a DC power supply to output multiple radio frequency signals, and at the same time, it can detect the working state of the test device. Therefore, it has the advantages of low cost and high test efficiency.

Description

technical field [0001] The invention belongs to the field of radio frequency communication, and in particular relates to a reliability test device and method. Background technique [0002] Reliability refers to the ability or possibility of a component, product, or system to perform its function without failure within a certain period of time and under certain conditions. Reliability testing is an activity carried out to ensure that a product maintains functional reliability in all environments of intended use, transportation, and storage during its specified lifespan. It is to expose the product to natural or artificial environmental conditions to undergo its action to evaluate the performance of the product under the environmental conditions of actual use, transportation and storage, and to analyze and study the degree of influence of environmental factors and its mechanism of action. [0003] Reliability test items mainly include: high temperature, low temperature, tempe...
