RF calibration test shielding box and control method thereof

Abstract

The invention relates to a radio frequency calibration testing shielded box and a control method of the radio frequency calibration testing shielded box. The radio frequency calibration testing shielded box comprises a box body, a to-be-tested equipment inlet and outlet mechanism, a probe lifting mechanism, a connecting mechanism and s control module. The to-be-tested equipment inlet and outlet mechanism is arranged in the box body and capable of being horizontally popped out and drawn back from one side face of the box body when carrying to-be-tested equipment. The probe lifting mechanism is arranged in the box body and is matched with the to-be-tested equipment inlet and outlet mechanism in work. The connecting mechanism is arranged in the box body and is connected with the to-be-tested equipment when the to-be-tested equipment inlet and outlet mechanism is drawn back in place. The control module is arranged in the box body and is in connection communication with an external computer so as to control matching work between the to-be-tested equipment inlet and outlet mechanism and the probe lifting mechanism. A probe on the probe lifting mechanism is connected with an external radio frequency alignment testing device through a radio frequency wire. The connecting mechanism is provided with a power connector and a network cable connector so as to power on the to-be-tested equipment and connect the to-be-tested equipment and the external computer through a network cable. Due to the fact that the radio frequency calibration testing shielded box and the to-be-tested equipment are integrated together through a connecting clamp to achieve uniform control and automatic motion, the radio frequency calibration testing shielded box and the control method of the radio frequency calibration testing shielded box reduce movements of production personnel and labor cost.

Description

technical field [0001] The invention relates to a radio frequency calibration test technology for wireless products, more specifically, to a radio frequency calibration test shielding box and a control method thereof. Background technique [0002] At present, when manufacturers of wireless products perform radio frequency (RF) calibration tests on wireless routers, the main combination mode of production test equipment used is: RF calibration tester (IQflex) + computer + pneumatic shielding box + device under test connection fixture. The topology diagram of the RF calibration test system is as follows: figure 1 As shown, the device under test 400 is placed in the shielding box 100, connected to the IQflex300 through the radio frequency line and connected to the network port of the computer 200 through the twisted pair to accept the test; the shielding box 100 is connected to the computer 200 through the serial line to receive the test control signal. The equipment that pro...

AI Technical Summary

Problems solved by technology

[0005] 1. In the whole test process, except that the test is completed by the computer, the pick-and-place and switch of the tested equipment are almost all done manually by the production staff. The production efficiency is low, the labor cost is high, and automation cannot be realized;

[0006] 2. The pneumatic shielding box itself is bulky, and the movement mode of opening and closing up and down makes the space occupied during the movement larger, resulting in a waste of production space;

[0007] 3. The control part of the pneumatic shielding box is old, the drive circuit is not perfect, the stability is poor, and new functions cannot be expanded;

[0008] 4. The software function of the control part of the pneumatic shielding box is less, and the robustness and scalability of the software are poor
