Embodiment Construction

[0010] A method for calibrating a multi-port wireless communication tester. During the calibration process, four functional areas of the multi-port wireless communication tester are required. These four functional areas are respectively the first functional area, the second functional area, and the third functional area. functional area and the fourth functional area. The first functional area is MPA RFIO, which is an 8-port input and output channel composed of Port 0 to Port 7, and its function is to perform bidirectional data transmission with the device under test. The second functional area is the MPA STATUS status indicator light, wherein the sending indicator light indicates that the corresponding port is sending data, and the receiving indicator light indicates that the corresponding port is receiving data. The Tx / DL RF OUT interface in the third functional area is the total output port of transmission signals or data downlink signals, and the MPA IN interface in the th...

Abstract

The invention relates to the technical field of tester calibration, and particularly relates to a multi-port wireless communication tester calibration method. The invention adopts the technical schemethat the multi-port wireless communication tester calibration method is characterized by comprising a signal transmitting function calibration step and a signal receiving function calibration step, wherein the signal transmitting function calibration step consists of a Tx / DLRF OUT output port calibration step and a MPA RFIO Port 0-7 output port calibration step; and the signal receiving functioncalibration step consists of an Rx / UL RF IN input port calibration step and a MPA RFIO Port 0-7 input port calibration step. The multi-port wireless communication tester calibration method has the advantages that a multi-port wireless communication tester calibration result can be guaranteed to be more reliable; in the calibrating process, efficiency is higher; and the multi-port wireless communication tester calibration method is more convenient in the process of carrying out the calibration operation.

Description

technical field [0001] The invention relates to the technical field of tester calibration, in particular to a calibration method for a multi-port wireless communication tester. Background technique [0002] The multi-port wireless communication tester needs to go through several strict calibration tests before leaving the factory to ensure its performance. The calibration test of the traditional multi-port wireless communication tester is carried out through other instruments and equipment, and the performance of the entire device is ensured through the overall calibration operation, but the detection efficiency of this method is relatively low, and sometimes it will cause missing detection In some cases, the calibration process may produce missing items, so that the products produced cannot be strictly calibrated. Contents of the invention [0003] The purpose of the present invention is to provide a multi-port wireless communication tester calibration method, which solv...
