Overview
The dual-channel SWR test module is equipped with two test channels (more test channel can be customized according to the user’s requirements), and can be used to measure the standing wave ratio and return loss and remotely locate the fault. The cable fault can be accurately located by means of DTF SWR and DTF ReturnLoss measurement. Measurement data of the module can be transmitted to the software through the LAN or RS485 interface. The software development interface library and Windows sample programs are provided to facilitate system integration and reduce the difficulties in development of custom software.
