APPLICATIONS

Convenient operating procedures, high sensitivity, excellent repeatability and exceptional performance enable the MS2721B to simplify measurements on wireless systems for easy verification of system compliance. Typical applications include:

• Transmitter Spectrum Analysis - occupied bandwidth, channel power, adjacent channel power ratio and modulation
• Received Signal Analysis - location and identification of in-band interference and out-of-band spurious signals and spectral masks
• Signal Strength Mapping - to determine the most suitable location for antennas, base stations and repeaters
• Field analysis of 3G signals – fast sweep speed, field-swappable battery, smart measurements and daylight-viewable display make the MS2721B an ideal choice for the challenge of rugged environments
• Broadcast measurement AM & FM analog and IBOC proofing measurements
• Interference mitigation in many diverse situations including wireless patient telemetry in hospitals
