    DPM-50 RF In Line Digital Power Meter

    DPM-50 has been designed for field engineers and technicians to perform power measurement in wireless network of various standards.

    DPM-50 features high dynamic range, high accuracy and high stability, it works with PC monitoring software and optional handheld monitor to perform real-time in-line monitoring on entire antenna system and saves test data for analysis and evaluation.

    The typical application is to monitor the transmitter and antenna of wireless base station during network installation and maintenance, DPM-50 can fast measure forward power of transmitter, reflected power of antenna and entire system’s VSWR. DPM-50 is the ideal tool for base station and antenna system measurement and troubleshooting.


      Measures 2G/3G wireless network, including GSM900/1800, CDMA800/1900, TD-SCDMA, WCDMA, CDMA2000, WLAN 2.4G & WiMAX or user-defined band
