Use the MA25100A RF Power Indicator to determine if a connector is "live" with RF power that could damage sensitive
measuring equipment from 400 MHz to 4000 MHz.
Mate the MA25100A to the connector in question and it will indicate the presence of high-level
RF: Yellow LED if RF > +17 dBm (50 mW) or Red LED if RF > +27 dBm (500 mW).
The MA25100A can withstand RF power levels up to +50 dBm (100 W) from a 50 Ω source. The MA25100A has a very
high VSWR and should not be used as a 50 Ω termination.
