  • Using External Filters To Maintain Sensitivity In Highly Dynamic Measurement Environments
    Using External Filters To Maintain Sensitivity In Highly Dynamic Measurement Environments

    Analyzing and measuring weak radio signals requires high sensitivity, and often necessitates the presence of strong radio signals. Unfortunately, this constraint leads to over modulation of modern measuring receivers and signal analyzers. It is therefore important to be able to recognize in-band and out-of-band interference, which can be done through the use of modulation effects in the form of harmonics and 2nd order intermodulation products. This application note explains the process of identifying and eliminating in-band and out-of-band interference, as well as how to use external filters in order to maintain high measurement sensitivity.

  • Multi-Tone Testing, Theory And Practice
    Multi-Tone Testing, Theory And Practice

    Multi-tone signals are composed of multiple single sine waves or tones with unique amplitudes, phases, and frequencies. Originally, multi-tone testing was implemented to increase the speed of immunity testing, but it also improves equipment efficiency, higher flexibility, and is fully compliant to standards. Multi-tones are also used in measuring modern audio levels in consumers and professional audio devices, broadband devices, and in internet audio. This application note further discusses multi-tone testing, the theory of the science behind it, and how to put it into practice.

  • SkyBridge Tools Proves To Be Winning Solution For Sports Venue DAS Installation
    SkyBridge Tools Proves To Be Winning Solution For Sports Venue DAS Installation

    As part of a new upgrade for a basketball arena in a large state university, the wireless network was to be improved to provide spectators with more venue coverage and capacity, particularly for high-bandwidth services. In order to meet this challenge, test tools were needed that could simplify the complexity of collecting thousands of traces to verify DAS installations as quickly as possible. The Anritsu Site Master™ handheld cable and antenna analyzers, PIM Master™ portable passive intermodulation analyzer, and the award-winning SkyBridge Tools™ Test Manager were used to reduce project testing time by 70 percent.

  • On-Orbit Satellite RF Measurements
    On-Orbit Satellite RF Measurements

    At the beginning of 2015, around 1200 satellites were fully operational in orbit around the planet, half of which were communication satellites. This number of satellites is expected to expand at a progressive rate within the next years. In order ensure proper performance in the satellite transponders in the payload, on-orbit measurements must be made as a part of maintenance. This application note focuses on satellite post-launch or on-orbit measurements, and monitoring strategies used for satellite functionality checks when running maintenance routines.

  • The Impact Of Return Loss On Base Station Coverage In Mobile Networks
    The Impact Of Return Loss On Base Station Coverage In Mobile Networks

    In many cases of designing and building cellular infrastructure, there are variables that the installers are and are not able to control. Important variables that are controllable are the losses in the cable feed system due to reflections and absorption. This white paper focuses on the system losses due to reflections, which can be measured using a cable and an antenna analyzer such as the Anritsu Site Master.

Mobile Interference Hunting System: MX280007A Mobile Interference Hunting System: MX280007A

Anritsu’s Mobile InterferenceHunter is a quick and reliable way to find multiple emitters, or single emitters even in difficult reception conditions. The ability to work with multiple signal sources, reflections, RF shadows, and multi-path distinguish the Mobile InterferenceHunter from conventional systems that depend solely on directional antennas. The ability to work with signals that are intermittent, bursty, or drift rapidly in frequency separate the Mobile InterferenceHunter from more expensive solutions targeted at a single fixed frequency interferer. The Mobile InterferenceHunter’s post-capture analysis capability allows users to modify search parameters without re-driving the route. This allows re-analysis of the captured data as well as consulting with experts.


  • CATV Leakage location
  • Simplified Spectrum Clearing
  • Locating interference – Even in the presence of uplink signals
  • Finding pulsed or bursty signals

 Key Features:

  • Post-capture analysis
  • Sorts out signal reflections, shadowing, and multi-path
  • Quick setup in any vehicle
  • Much faster than conventional direction finding techniques
