Anritsu MA25100A RF power indicator

One of the most common ways to damage an instrument is by exposing the front end of the equipment to too much RF power, in most cases rendering the instrument useless. The MA25100A will provide an indication to the user if excessive power is present so that they can determine if an attenuator needs to be inserted before connecting to the RF cable in question.

Mate the product to the connector and it will indicate the presence of high-level RF. The yellow LED will light up if RF is >17 dBm (50 mW) or the red LED will light up if RF is >27 dBm (500 mW).

The device comes with a 7/16″ DIN (m) connector. It can withstand RF power levels up to 50 dBm (100 W) from a 50 Ω source and operates over the frequency range from 400 to 4000 MHz. The product has a very high VSWR and should not be used as a 50 Ω termination.

The 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.
