Four Channel Power Measurement Must-Haves for Your Field Kit
白皮书
Introduction
Modern communications — such as cellular, radar, and navigation signals — have complex modulation formats. These wireless systems depend on digital modulations at very high data rates and other spread-spectrum formats. The transmitted and received power levels of such systems play critical roles in the overall performance and compliance of those systems.
In communication system development and deployment, power level measurements are important for designing, prototyping, manufacturing, testing, installing, maintaining, and troubleshooting. In radar and electronic warfare, power measurements give you valuable information about signals from unknown targets. In cellular communications, where governing agencies enforce strict regulations, power level measurements ensure mobile operators meet standards.
Having power measurement capabilities in your field kit will help you verify and optimize performance specifications while meeting compliance regulations.
This white paper covers four channel power measurements you can make in the field:
- Channel power (CHP)
- Occupied bandwidth (OBW)
- Aadjacent channel power (ACP)
- Spectrum emission mask (SEM)
