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.
