Receiving sensitivity test system and method

Abstract

The invention provides a receiving sensitivity test system and a receiving sensitivity test method. The system comprises a transmission module, an adjustment module, current equipment to be tested anda control module, wherein the transmission module sends test messages to the adjustment module according to a preset working parameter under the control of control equipment; the adjustment module gates a test circuit under the control of the control equipment, and adjusts an attenuation value of the gated test circuit until the quantity of the adjusted test message received by the current equipment to be tested reaches a preset threshold; the current equipment to be tested receives the test messages adjusted by the adjustment module; the control module reads a register value of the transmission module when the quantity of the adjusted test messages received by the current equipment to be tested reaches the preset threshold, and works out receiving sensitivity of the current equipment tobe tested according to the register value and the attenuation value; the test circuit is a connection circuit between the equipment to be tested and the adjustment module; and the current equipment tobe tested is the equipment to be tested connected with the gated test circuit. According to the system and the method provided by the invention, test time is reduced, test efficiency is enhanced, andtest cost is reduced.

Description

technical field [0001] The invention relates to the field of communication testing, in particular to a receiving sensitivity testing system and method. Background technique [0002] With the development of the Internet, receiving sensitivity is a key indicator of the terminal's communication capability, which directly affects the receiving performance of the entire terminal. The quality of communication performance has become an important criterion for judging the quality of radio frequency equipment. [0003] At present, the receiving sensitivity test is through manual testing, and because wireless radio frequency has different frequency bands, modes, rates and channels, special testing equipment is required as a signal source, by changing the output signal power level of the signal source, and providing signal output with different modulation types , and then the device under test receives the signal source, calculates the corresponding packet loss rate, and the power leve...
