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.
Benchmark Simulations Of Waveguide Components
There is a driving need for more accurate and compact waveguide components at higher frequencies, while maintaining cost-effective solutions. This application note presents a handful of benchmark simulations of waveguide components performed with FEKO.
Making EMI Compliance Measurements
Electrical or electronic equipment that uses the public power grid or has potential for electromagnetic emissions must pass EMC (electromagnetic compatibility) requirements. These requirements fall into four broad types of testing: radiated and conducted emissions testing, and radiated and conducted immunity testing. Conducted emissions testing focuses on signals present on the AC mains that are generated by the equipment under test (EUT). This application note introduces the basics of EMI compliance measurements, as well as the measurement process and regulations.
Basic Bulk Current Injection Testing
Bulk current injection (BCI) testing is a conducted susceptibility procedure that uses an injection current probe. This paper provides an example of BCI testing, covering all steps, including gathering the required equipment, pre-calibration procedures, injection testing procedures, and safety precautions.
Noise And Noise Figure: Improving And Simplifying Measurements
As noise and noise figure measurements have become increasingly complex, signal analyzers have evolved to support easy-to-use measurement applications that help reduce complexity while instilling confidence that the results are accurate. This application note presents a number of ideas to help improve noise figure and noise figure measurements using a compact system based on a Keysight X-Series signal analyzer, an internal or external preamplifier, and an external noise source.
