vswr monitorDescription
The NMVW series features an advanced digital VSWR monitor, designed for reliable, long term GSM/CDMA site transmitter RF monitoring. The device provides alarms for the malfunctions found on the RF path like antenna, connectors or cable damages. Through directional couplers and microprocessor control the device provides “state of the art” accuracy and functional versatility. Using an intelligent algorithm base on data interpolation, the device avoids false alarms, and provides a better way to minimize GSM/CDMA coverage malfunctions of the network. The control channel can be used for sending the alarms from the site to the supervising center.
