RF Power Indicator MA25100A
The MA25100A RF Power Indicator is always on and always ready. Its self-contained battery can last for years with normal use and is field-replaceable. A "self-test" button lights both indicators (red and yellow) if internal circuits and battery are functioning.
- 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
