Embodiment Construction

[0038] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0039] The present invention aims at the method of testing radio frequency line loss in the prior art which relies on complex testing system, complicated operation, high cost, unfriendly man-machine interface, inaccurate obtained line loss value which brings serious quality problems and cannot adapt to various To solve the problem of product demand, provide a method to test the loss of radio frequency line, such as figure 1 shown, including:

[0040] Step 11: controlling the measuring instrument to transmit the first power signal;

[0041] Step 12: Control the power testing equipment to obtain the second power signal output after the radio frequency line to be tested receives the first power signal;

[0042] Step 13: Analyzing and calculating the first...

Abstract

The present invention provides a method, apparatus and system for measuring RF line loss. The method includes the steps as follows: controlling a measuring instrument to emit a first power signal; controlling a power measuring apparatus to acquire a second power signal outputted by a RF line to be measured after the RF line receives the first power signal; analyzing and calculating the first power signal and the second power signal so as to obtain the line loss of the RF line to be measured. According to the scheme provided by the invention, the power signal of the input RF line and the power signal of the output RF line are directly analyzed and calculated so that the line loss is acquired without experience depending, and the acquired line loss is accurate. A gold machine is needless so that the measuring system is simplified, the cost is reduced, the better human-computer interface is provided, the operation is simple, the user experience is improved, and the requirement for acclimatizing various products is met.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a method, device and system for testing radio frequency line loss. Background technique [0002] At present, the line loss value of the radio frequency line that transmits the radio frequency signal depends on the complex test system in the traditional test, which is costly and requires professional operators. Lead to mobile terminal quality problems. [0003] However, there are currently two commonly used solutions: the first one is to perform line loss compensation on the radio frequency line based on empirical values, which cannot be adapted to a variety of products, and the inaccurate line loss value will cause serious quality problems. The second is to use a gold machine as a reference. The test system is complex, high cost, and requires professional operation. The man-machine interface is not friendly and cannot be adapted to various products. Contents of the inve...
