Product Overview
The Ceyear 3681 Feedline Tester covers a frequency range of 300kHz to 9GHz, featuring testing capabilities for cable loss, standing wave ratio, and return loss. It allows for precise fault location using either the Standing Wave Ratio or Return Loss fault location functions to identify minor issues, thereby eliminating potential faults.
The 3681B Antenna Feedline Tester features compact size and lightweight design, making it easy to carry and suitable for use in confined testing spaces. The unit is equipped with a 10.1-inch LCD touch screen, offering simple operation and a user-friendly interface, which enhances the efficiency of field testing for users.
The 3681BU Antenna Feedline Tester utilizes USB 3.0 bus communication, featuring compact size, high efficiency, and flexibility. It is suitable for applications requiring high mobility, portability, and reliability in test systems, such as communication system testing and RF component testing. Additionally, it can be used in scenarios with high demands for system automation and testing efficiency.
