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.
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.
How To Analyze Passive Low Frequency Components With A Rohde & Schwarz Oscilloscope
This white paper presents a technique for easily and quickly analyzing low frequency response on an oscilloscope with the R&S®RTx-K36 frequency response analysis (Bode plot) option, which uses the oscilloscope’s built-in waveform generator to create stimulus signals ranging from 10 Hz to 25 MHz.
How To Test USB Power Delivery Over Type-C
USB Type-C compliance test standards are more complex due to higher data transmission speeds and more power. Successful testing requires accurate and compliant test instruments, software, and fixtures.
Ensuring Test Site Compliance for Radiated Emissions With Normalized Site Attenuation
This application note provides a synopsis of Normalized Site Attenuation (NSA) and Reference Site Method measurements which indicate a challenging but important aspect of radiated emissions measurements on an OATS, SAC, or FAR.
