Mobile Spherical Near-Field Multi-Probe Testing System

CT-24M Spherical Near-Field Multi-Probe Testing System is a mobile OTA (Over-the-Air) and antenna testing anechoic chamber equipped with 24 probes. Designed and built in accordance with the sampling requirements specified in CTIA (Cellular Telecommunications and Internet Association) standards, it supports a frequency range of 600MHz-8GHz (upgradeable to 12GHz). Featuring a compact footprint and flexible mobility, the system can be quickly set up and put into operation. It is equipped with the latest self-developed algorithms and software by Sai sheng Technology, supporting comprehensive antenna parameter testing as well as OTA testing for all common mobile communication and wireless broadband standards, such as 2G, 3G, 4G, 5G, WIFI, and BT. Additionally, it supports non-signaling active testing. With stable and fast testing performance, the system is an optimal wireless testing solution for antenna and complete device development in fields like mobile communications, the Internet of Things (IoT), and laptops.
