TEST & MEASUREMENT APPLICATION NOTES AND WHITE PAPERS

• Power Consumption Analysis With Specialty DC Power Supplies

  Optimizing power consumption is critical for IoT devices running on small, non-rechargeable batteries. Learn how accurate characterization and smart design can extend device lifespans.

• DPX® Acquisition Technology For Spectrum Analyzers Fundamentals

  Signal detection is the first step in characterizing, diagnosing, understanding, and resolving any problem that relates to time-variant signals. Engineers are requiring better tools to help find and interpret complex signal behaviors and interactions. The Tektronix Digital Phosphor technology, or DPX®, can be used in Real-Time Spectrum Analyzers (RSAs) to reveal signal details that are completely missed by conventional spectrum analyzers and vector signal analyzers. This white paper describes the methods behind the DPX Live RF spectrum display, swept DPX, Time-Domain DPX Displays, DPX Density™ measurements, DPX Density™ and Frequency Edge triggers.

• 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.

• 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.

• VSWR Conversion To Reflected Power

  VSWR measures how efficiently RF power is transmitted through a load, with high VSWR indicating poor efficiency. Explore VSWR's relation to return loss, reflection coefficient, and mismatch loss.
