Inline power sensor measures accurate peak and true-RMS measurements

Anritsu Company has launched its new inline power sensor MA24103A, which was created to measure accurate Peak and True-RMS average power measurements from 25MHz to 1GHz and 2mW to 150W power range.

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

Lower frequencies have the advantage of propagating a longer distance and maintaining communication with fast-moving vehicles. Normally, at lower frequencies, the power of the transmitting signal is in the range of watts, which makes the device more suited for these types of applications.

This highly accurate sensor communicates with a PC via USB or an Anritsu handheld instrument equipped with the high-accuracy power meter option 19.

Some of the main markets that profit from this low-frequency sensor include:

Broadcast Network and Manufacturers with lab performance accuracy and low insertion loss over a wide temperature range (0C to 55C), making it ideal for field applications.

Evaluating various systems, such as positive train control systems, end-of-train signals, automated train control systems, and FM voice base stations.

In avionics, such as civil and defence airports for beacon testing, surveillance radar testing, localiser, and marker testing.
