Overcoming High-speed Interconnect Challenges

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.

Calculating VNA Measurement Accuracy

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.

Synchronization for Next Generation Networks - The PTP Telecom Profile

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.

Advanced VNA Cable Measurements

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.

Oscilloscope Fundamentals

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.

Accurate System Level Design with Low Noise Amplifier's BlackBox Models

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.

5 RF Transmitter Measurements Every Engineer Should Know

RF transmitters are an essential part of modern communications. Designed and assembled from core RF components, RF transmitters have many different forms and applications. We often think of RF transmitters in wireless communications, but the concept applies equally to wired applications such as cable television.

Understanding VNA Calibration

In this guide, the concept of calibration is presented and discussed in detail. Specific topics to be covered include how to configure the VNA for calibration, types of calibration and calibration kits. A minimal amount of calibration mathematics and theory will also be covered.

Using RF Recording Techniques in PXI to Capture and Analyze Interference in the Signal Environment

The airwaves are becoming increasingly crowded as demand for RF spectrum continues to grow. As a result, every type of wireless communication system faces a complex and unpredictable signal environment.
