Developers of wireless products that need to push to the higher communication bands now have access to an affordable VNA for operation up to 6 GHz. The new MegiQ VNA-0460 VNA measures impedances and other S-parameters from 400 MHz up to 6 GHz.
Anritsu Co. introduces CPRI RF measurement capability in its market-leading E series of Site Master™, Spectrum Master™ and Cell Master™ handheld field analyzers that dramatically simplifies and lowers the cost of testing Remote Radio Heads (RRHs) installed atop 4G towers.
Spectrum GmbH has released its first high-speed digitizer product line based on the popular PXIe (PXI Express) modular instrumentation standard. The M4x.44xx series consists of six new products, each packaged in a dual-width 3U module and incorporating a four lane PCI Express Generation 2 interface.
This application note compares the commonly-implemented power measurement test setups for TVAC with a new test method that uses TVAC-qualified LAN power sensors. The paper explains how this new test method provides a simplified test setup, and more accurate and reliable microwave power measurements for TVAC testing of satellite equipment.
Cloud computing, smart phones, and LTE services are causing a large increase in network traffic. Instantaneous traffic rates at internet data centers have reached 1 Tbit/s. Supporting this increased traffic, speed of IT equipment used in high-end services in data centers must be increased. This white paper discusses challenges introduced at these higher data rates and how Vector Network Analyzers can help meet these.
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.
This paper is designed to help network engineers, network planners, and network operations understand how to deploy Precision Time Protocol (PTP, or IEEE 1588). PTP is a next generation, packetbased timing protocol targeted for use in asynchronous network infrastructures based on packet transport technologies.
This field brief will discuss phase-matching cables, S-parameter definitions as they apply to cable characterization and other cable parameters such as Phase Shift and Group Delay. Advanced Time-Domain measurements will also be presented as enhancements to the well-known Distance-to-Fault (DTF) techniques. In addition, diagnostic tools like the Smith Chart will be briefly described.
The oscilloscope is arguably one of the most useful tools ever created for use by electronic engineers. In the more than five decades since the modern analog oscilloscope was created, hundreds of useful documents and thousands of articles have been written about what it is, how it works, how to use it, and application-specific examples of the oscilloscope in action. It is the purpose of this primer to instead describe digital oscilloscopes, which have for practical purposes replaced their analog predecessors in the vast majority of applications.
To amplify weak signals received by the antenna in communication systems, low noise amplifiers (LNAs) are deployed. LNAs are used in various applications such as GPS receivers, wireless data systems, satellite communications, cellular handsets, radio systems, etc.
