Anritsu MA24103A inline power sensor for LMR networks

Click2Contact

Anritsu has announced the launch of its latest inline power sensor, MA24103A, designed to measure accurate peak and true-RMS average power measurements from 25 MHz to 1 GHz and 2 mW to 150 W.

Several applications demand accurate peak and average power measurements well below the frequency range of 1 GHz. Agencies in public safety, avionics (air traffic control and repair stations), railroads and more must maintain critical communications between the control centres and the vehicles. The slightest error in making measurements or maintaining a communication network in these markets could risk public safety or even have fatal consequences.

The advantage with lower frequencies is that they can propagate a longer distance and maintain communication with fast-moving vehicles. Normally, at lower frequencies the power of the transmitting signal is in the range of watts, which makes the MA24103A more suited to these types of applications. The inline peak power sensor communicates with a PC via USB or with an Anritsu handheld instrument equipped with the High Accuracy Power Meter (Option 19).

LMR network operators can deploy the sensor to measure forward and reverse power in P25, DMR and TETRA networks over a wide temperature range (0 to 55°C), making it suitable for field applications. With lab performance accuracy and low insertion loss the sensor may also be used in broadcast networks, railway signalling networks and avionics — such as civil and military airports for beacon, surveillance radar and marker testing.
