TEST & MEASUREMENT APPLICATION NOTES AND WHITE PAPERS

• VCO Measurements With FSPN Phase Noise Analyzer

  This application note provides a short technical introduction to voltage-controlled oscillators and explains the most common and the most important measurements made during the VCO characterization process.

• Field Probe Correction Factors

  To better achieve accurate field level measurements, it is helpful to have an understanding of field probe calibrations, the factors generated, and what’s presented as data during testing. This application note presents how to utilize the factors presented for inclusion into test data, how to generate composite measurements, and why calibrations are performed at selected frequencies.

• Wi-Fi Performance In A House With Two Routers

  Wireless InSite’s Communication System Analyzer provides capabilities for assessing the performance of LTE, WiMAX, 802.11n, and 802.11ac systems. This example investigates WiFi throughput coverage in a house provided by 802.11ac routers operating at 5 GHz using an 80 MHz bandwidth.

• 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.

• What Is Pulse Shaping?

  In this industry briefing,George Bollendorf explains a new approach to fix fidelity issues caused by the transmitting amplifier that matches input pulse signal shape, minimizes droop, overshoot, ringing, and rise and fall times.
