Automatic test system and method for OOK electric performance modem

Abstract

The invention discloses an automatic test system and method for an OOK electric performance modem. The system comprises a test tool used for fixing a to-be-tested modem and controlling an OOK electric performance test of the modem; and an automatic test gear and a manual test gear are arranged on the test tool, when the automatic test gear is selected, the test tool is electrically connected with a computer through a USB interface, and when the manual test gear is selected, the test tool is directly connected with a DC power supply for charging. According to the automatic test system and method for the OOK electric performance modem disclosed by the invention, the system communicates with a test platform through the USB interface, and the transmission and reception of the OOK modem are controlled by a 485 interface or a 232 interface. The transmitting power of the modem and the receiving threshold of the modem are non-destructively tested in two modes of automatic and manual, thereby both guaranteeing the production quality and guaranteeing the production efficiency.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an automatic test system and method for an OOK electrical performance modem. Background technique [0002] With the advent of the 3G and 4G era, the optimization and adjustment of the wireless communication network has become more and more frequent. The electric adjustment equipment can effectively enhance the coverage of the cell and reduce the interference to the adjacent cell. It has good real-time performance, high precision, and adjustment It has the advantages of wide range and convenient adjustment. [0003] The ESC equipment at the antenna feeder communicates with the base station through the OOK signal. In the 3GPP protocol, the transmit power of the OOK modulator at the base station and the antenna feeder is specified as 3dBm±2dBm, and the effective receiving power of the OOK demodulator is specified as >-12dBm. The invalid received power is specified as <...

AI Technical Summary

Problems solved by technology

However, since the OOK modulation and demodulation circuit is a module integrated in the system, it is impossible to test this indicator separately

Traditionally, it is necessary to jump wires from the system to test the circuit module, which will cause certain damage to the product. It is not suitable for batch testing, and it is difficult to ensure production quality and efficiency.
