TEST AND MEASUREMENT APPLICATION NOTES AND WHITE PAPERS
Application Note: Practical Tips On Measuring Interference By utilizing the ISM (Industrial-Scientific-Medical) frequency bands, the wireless industry has been able to exploit the increasing popularity of unlicensed communication systems. However, their unlicensed nature carries with it the seeds of serious signal interference problems. Such ISM system designs are type-approved but are then installed by unlicensed owners or contractors. These conditions sometimes lead to signal configurations that unintentionally interfere. The objective of this article is to present measurement tips and procedures which will help a field technician measure signal interference in operating communications systems. By Anritsu Company
MHL2.0 Compliance Testing
This application note provides an overview of the MHL technology and also describes the Rohde & Schwarz compliance test solution for the system part of the current MHL2.0 standard version.
Next-Generation (3G/4G) Voice Quality Testing With POLQA
This white paper provides details on the POLQA® (Perceptual Objective Listening Quality Assessment) algorithm. According to the recommendation of International Telecommunications Union, POLQA® is the next generation mobile voice quality testing standard. An example hardware setup for standard independent audio measurements is also included in the white paper. By Rohde & Schwarz
Field Analyzers In EMC Radiated Immunity Testing
In radiated immunity testing, it is common practice to utilize a radio frequency (RF) field probe to measure the electric field at the location of the unit under test (UUT). Most RF field probes are designed to measure the root mean square (RMS) of a continuous wave (CW) electric field over a broad range of frequencies and amplitudes.
Measurements on FM Transmitters for Acceptance, Commissioning and Maintenance
Despite the advent of advanced digital transmission methods, analog broadcasting remains highly important. Until now, measurements on FM transmitters in connection with acceptance testing, commissioning and maintenance required using a variety of T&M instruments.
