Application Note: Fundamentals Of Interference In Wireless Networks
1/13/2010
As wireless systems proliferate worldwide, the number one enemy of wireless systems designers and service providers is signal interference. Interference hampers coverage and capacity, and limits the effectiveness of both new and existing systems. It is an unavoidable fact that wireless communications systems must coexist in extremely complicated signal environments. This article presents the subject of interference and its degrading effects on the performance of wireless networks. It provides a brief theory of operation of communications receivers and antennae, as well as instructions on how to locate and identify an interfering signal. By Anritsu Company

Application Note: Distance To Fault Measurements For Cable And Antenna Installation And Maintenance
9/12/2005
By Anritsu Company
Distance To Fault (DTF) is a performance verification and failure analysis tool used for antenna and transmission line service and maintenance. It uses the Frequency Domain Reflectometry (FDR) measurement technique. FDR is a transmission line fault isolation method which precisely identifies signal path degradation for coax and waveguide transmission lines... -
Application Note: Cell Master Average Cable Loss Measurement
8/26/2005
Traditionally, measuring the insertion loss of an installed coaxial cable is a one-port reflection measurement since it is virtually impossible to connect both ends of the cable to test equipment...

Application Note: Calculating VNA Measurement Accuracy
7/13/2010
Vector Network Analyzers (VNA) are your primary resource when analyzing and characterizing systems and components for RF and Microwave measurements. They are regarded as accurate measuring instruments, however, quantifying the accuracy performance of a VNA in a specific application can be challenging. VNA specifications are a starting point; but, they are based upon very specific calibration and measurement conditions, which are not applicable for many applications. The Anritsu Exact Uncertainty program is available to help you obtain the uncertainty data that is appropriate for your specific application.

Accurately Characterize Loss and Reflection of Long, Embedded Coaxial Transmission Systems
5/13/2014
This application covers an introduction to typical problems that occur when coaxial transmission systems are permanently installed in an enclosed environment, the benefits of swept frequency measurements over single or multiple CS frequency point measurements (along with a detailed list of what is needed to perform said measurements), step-by-step instruction of the procedure, and more
