APPLICATIONS
Avionics
  • Antennas and Airport Beacons, situated atop towers and buildings, antennas and airport beacons serve as guiding lights for pilots, with systems like the Instrument Landing System (ILS) operating within the frequency range of 108.10 to 111.95 MHz, providing precision guidance during adverse weather conditions.
  • Broad spectrum of equipment operating within frequencies ranging from 75 MHz to 336 MHz such as Localizers, Glide Paths, Surveillance Radars, and Markers, each playing a unique role in navigation, surveillance, and communication within the airport environment.
  • In Civil aviation, communication systems operate within to 137 MHz, facilitating seamless interaction between air traffic controllers and pilots.
  • Military aviation relies on the UHF frequency band, spanning from 225 to 400 MHz, to meet its operational needs.
Railroad Braking Systems
  • Real-time Monitoring and Feedback: Railroad braking systems require precise control to ensure trains stop safely and efficiently. Anritsu’s Inline Peak Power Sensors can be integrated into the braking system to provide real-time monitoring of power levels. By continuously measuring the peak power, these sensors offer instant feedback on the braking system’s performance, allowing for immediate adjustments if any anomalies are detected.
  • Enhanced Safety: Safety is the foremost concern in railroad operations. The MA24103A and MA24105A sensors enhance safety by ensuring that the braking system operates within the optimal power range. By preventing power surges or drops that could lead to brake failure, these sensors play a crucial role in maintaining the integrity of the braking mechanism, thereby reducing the risk of accidents.
  • Predictive Maintenance: Integrating Anritsu’s power sensors into the braking system allows for predictive maintenance. The sensors can detect slight deviations from the norm, indicating potential wear and tear or impending failure of components. This early warning system enables maintenance teams to address issues before they escalate, reducing downtime and maintenance costs.
  • Performance Optimization: The efficiency of braking systems directly impacts fuel consumption and overall train performance. Anritsu’s sensors help in fine-tuning the braking system by providing detailed power measurements.
  • Compliance with Regulations: Railroad systems are subject to stringent safety and performance regulations. The accurate and reliable data provided by the MA24103A and MA24105A sensors can help railroad operators meet these regulatory requirements. Detailed records of braking performance can be maintained, demonstrating compliance, and aiding in the certification processes.
Broadcast Networks and LMR Systems
  • Transmitter Power Monitoring: This sensor can continuously monitor the power output of base station transmitters, ensuring that they operate within specified power levels. This monitoring helps maintain signal quality and network reliability.
  • Antenna Reflection Measurement: This information helps in optimizing antenna performance and minimizing signal loss due to reflections, ensuring efficient signal propagation.
R&D and Manufacturing
  • Testing high power devices such as Power Amplifiers
  • General purpose measurement of through and reflected power
