Equipment Introduction

We introduced the American Keysight E7515B 5G Communication Tester at the end of 2019. It can be used for RF testing of NR, NR CA, LTE (QPSK, 16QAM, 64QAM, 256QAM modulation), and LTE CA. It can also assist customers in conducting physical layer verification, conformance testing, and throughput testing.

The 5G Communication Laboratory possesses 1 set of NR testing system, 2 sets of LTE testing systems, and 2 sets of WCDMA testing systems. It is capable of conducting large-scale automated testing, which significantly saves time and costs while maintaining outstanding accuracy and high efficiency.

In today's era where quality dictates market success, JJR will adhere to a high-end strategic positioning, continuously improve laboratory capabilities, and expand our service network. Through continuous improvement and constant transcendence, we are committed to becoming an excellent and impartial organization in the testing field. We strive to provide guarantees for the product quality and safety of various enterprises, and escort our customers' products as they enter the market and participate in global competition.
