Product Overview

The Ceyear 3681 series cable and antenna analyzer has a frequency range of 300 kHz to 9 GHz and can test parameters including cable loss, VSWR and return loss. It can also identify minor issues through its VSWR or return loss fault location function, thereby eliminating potential faults.

The 3681B features a compact, lightweight design for easy transport and operation in confined spaces. With a 10.1-inch LCD touchscreen, it provides an intuitive interface for enhanced field testing efficiency.

The 3681BU cable and antenna analyzer works based on USB 3.0 bus communications. Compact, efficient and flexible, it is ideal for applications requiring high mobility and portability in test systems, such as communication and RF component testing. It is also applicable in scenarios requiring high automation and test efficiency.

Main Features

• Practical antenna and feeder analysis

The return loss and 1-port cable loss can be tested
The distance to fault (DTF) function is provided
The TDR cable analysis capability can be used to determine the location and nature of the fault (e.g. short circuit or open circuit)

• Supporting embedded calibration

Test efficiency can be improved by implementing one-button calibration without the need for external calibration kits
