In this course, learn the theories behind RF test measurements and how they can be used practically in field applications. See demonstrations of how a handheld instrument can solve real world problems.
Lesson 1 - FieldFox Overview
Get to know the FieldFox handheld RF and microwave analyzer, the main instrument used in this course. Learn its basic features and capabilities, and how to use it to perform basic RF measurements like power, frequency, and spectrum analysis.
Lesson 2 - Introduction and Distance-to-Fault Measurements
Learn how to use the FieldFox to perform distance-to-fault (DTF) measurements. DTF measurements can be used to identify and locate cable faults in RF systems.
Lesson 3 - Network Analysis and S-Parameters
Understand the concept of S-parameters and how they can be used to analyze RF networks. S-parameters are a set of complex numbers that describe the reflection and transmission characteristics of an RF network.
Lesson 4 - Smith Charts and Calibration
Learn about the Smith chart, a graphical tool that can be used to visualize and analyze S-parameters. The Smith chart is a powerful tool for understanding the behavior of RF networks.
Lesson 5 - Signal Analysis
Explore the basic concepts of signal analysis, such as frequency domain analysis and time domain analysis. Learn how to use the FieldFox to perform signal analysis.
Lesson 6 - Real-Time Spectrum Analysis and Finding Quick Signals
Learn how to use the FieldFox to perform real-time spectrum analysis, and how to use this technique to quickly find signals in a crowded spectrum.
Lesson 7 - Pulse Analysis and Time Domain
Learn about pulse analysis, a technique for analyzing signals in the time domain. This technique can be used to measure the rise time, fall time, and amplitude of a signal.
Lesson 8 - Channel Scanning
Learn how to use the FieldFox to perform channel scanning, a technique for quickly measuring the power of all the channels in a given frequency range.
Lesson 9 - Field Testing and Signal Hunting
Learn how to use the FieldFox to troubleshoot RF systems in the field. This lesson covers techniques for finding and identifying signal sources, and for determining the cause of RF problems.
Lesson 10 - Extended Range Transmission Analysis
Learn about ERTA, a technique for measuring the attenuation of an RF signal over a long distance. This technique can be used to characterize the performance of RF links.
Lesson 11 - FieldFox Testing Conclusions
Covers the key concepts and techniques covered in the course. It also provides some additional resources for further learning.
Signal Analysis Solutions
Communication networks are moving from voice and data communications to full-blown connected application ecosystems. Technological innovations will support the consolidation of communication systems under one 5G roof to meet end-user application needs. This includes data, voice, video, Internet of Things (IoT), and crucial communications. The 5G connected application ecosystem will provide much higher throughput, ultra-low latency, dramatically increased network capacity, reliability, and secure services.
Techniques for Precise Cable and Antenna Measurements
This application note introduces the practical aspects of cable and antenna testing, interpreting measurement results, and instrument operation. It looks at calibration options such as CalReady and QuickCal using a Keysight FieldFox handheld analyzer configured as a cable and antenna analyzer. Measurement examples show techniques for measuring insertion loss, measuring return loss, and locating faults in a transmission system.
Techniques for Advanced Cable Testing
When the purpose of the transmission line is to interconnect devices and distribute signals, the physical geometries of the conductors and dielectric properties of the supporting material will be uniform across the length of the line. When a change occurs in these characteristics, such as point of contact between two different lines or damage along the line, these discontinuities may result in signal reflection and higher line attenuation.
