TEST & MEASUREMENT APPLICATION NOTES AND WHITE PAPERS

• RF Amplifier Output Voltage, Current, Power, And Impedance Relationship

  How much output voltage, current, and power can you expect from your amplifier? In rare cases, this can be answered by applying Ohm’s law, assuming that the net power or power delivered to the load is the rated power output of the amplifier. In most cases, practical issues such as VSWR and forward power concerns must be considered before applying Ohm’s law. This application note addresses this issue and discusses an approach to be used that applies actual test data when calculating output parameters.

• Battery Simulation With DC Power Supplies

  This application note guides users in creating custom battery models for R&S^® NGM200 and R&S^® NGU201 power supplies, enabling gradual battery discharge via QuickArb and data logging, with recorded data adaptable for battery simulation using a provided developer tool.

• Characterizing Parasitic Components In Power Converters

  With the rise of wide-bandgap semiconductors like GaN and SiC, characterizing parasitic components in power converters is crucial for maintaining efficiency and preventing performance issues.

• Noise Figure: What Is It And Why Does It Matter?

  Noise figure is a key parameter that quantifies receiver performance by measuring how low a power a signal receiver can detect. This white paper covers the basic principles of noise figure, how to make sense of its specifications, how it is measured, and why this parameter is important in high-performance applications.

• Combining On-Wafer VNA And Spectrum Analyzer Measurements

  This app note describes how S-parameters and spectrum analysis can be monitored simultaneously from 70 kHz to 110 GHz using the VectorStar ME7838A, the Spectrum Master MS2760A, and the Anritsu MN25110A W1 coaxial precision directional coupler.
