The LTE CA measurement software sends commands through the GPIB line to control the R&S CMW500 tester to aggregate together the two LTE member carriers to transmit a dual channel carrier aggregation signal, and once the signal is processed by radio frequency, it will be passed to the probe array via RF cable.According to a specific algorithm, the LTE CA measurement software controls the probe array combination switching to transmit the dual carrier signals to DUT via two probes in arbitrary combination direction in space to form an ideal channel model. Once the DUT receives the dual carrier signals from different directions, it will carry out frequency conversion, demodulation and other baseband processing to get relevant demodulation parameters. The communication loop is formed by transmitting the link antenna in the mast to the receiving port of the CMW500.Applicable LTE CA OTA Measurement Solution

- RSE（Radiated Spurious Emission）test is an important required test item for Radiated objects such as mobile phones and Bluetooth headphones. Both the 3GPP standard and the FCC's North American standard have strict requirements for this. The problem of radiation dispersion is a complicated and troublesome one in the research and development of mobile phones. In order to help designers to solve the problem of radiation stray, we launched a radiation stray test program for customers.

- A disc single axis turntable that can achieve 360 ° free rotation. The central shaft is connected to the rotating table using large-sized rotary bearings, which have high vertical load-bearing and anti overturning force. The load-bearing guide wheel below the turntable has a load of 1 ton each, and the height of the guide wheel can be adjusted to ensure the level of the turntable when the ground is uneven. When the car enters the turntable, the force is concentrated in the area where it enters, and the guide wheels are densely arranged in the direction where the car enters.
