CST PCB STUDIO (CST PCBS) is a specialist tool for signal integrity (SI), power integrity (PI), and electromagnetic compatibility (EMC)analysis on printed circuit boards (PCB). It integrates easily into your design flow by providing powerful import filters for popular EDA tools from Cadence, Mentor Graphics, Zuken, and Altium. Prior to modeling and simulation, the imported layout is automatically checked in order to correct potential geometric errors.

The volume of broadband data transmitted in cable systems has increased tremendously over the last decade. Since 2003, the number of subscribers to broadband data cable services has increased at a compound annual growth rate approaching 14% . The annual growth rate has since slowed, but recent trend information shows double digit growth in premium, so called "wideband" broadband services.

Trying to increase battery life? Trying to be green or increase energy efficiency? If so, then current consumption is most likely one of your key concerns. Today's multi-tasking, battery-powered devices boast powerful processors, incorporate back-lit touch-screen displays, and have amassed multiple radio receivers and transmitters that are sending and receiving data at unprecedented rates.

This application note is designed to help you get insight into solving tough measurement problems in a unique way for both the design and manufacturing environments by explaining how to use simulated satellite signals to quickly and accurately verify GNSS receiver operation. The successful proliferation of GNSS receivers worldwide requires today’s engineers to effectively test GNSS receivers with multi-GNSS signals. A real-time GNSS simulator like the N7609B, with its flexibility, functionality and performance is well suited to address this task. Combined with the power of an EXG/MXG X-Series signal generator, it provides the real-time simulation of GPS, GLONASS and Galileo L1/E1 signals that is so critical to quickly and accurately testing today’s GNSS receivers.

There are several options for the architecture of the transmit signal path. The factors that impact transmit signal elements are introduced, followed by a discussion of the different architectures. Figure 1 shows a direct conversion architecture for an initial point of reference only. Section 6 of 3GPP TS 25.105 describes the transmit signal requirements used throughout this discussion.

The IP Multimedia Subsystem (IMS) dates
from 3GPP release 5 almost a decade ago,
but is now becoming a reality with the rollout
of IMS-based LTE networks. IMS enables
convergence on multiple fronts, including
access types (fixed, mobile), service types,
application control functions and convergence
between telephony and traditional data
delivery. This paper presents a high-level technical
view of the IMS architecture as seen by LTEcapable
User Equipment (UE).

Signals intelligence describes a broad range of applications ranging from communications jamming to identification of interference or pirating signals. While this paper discusses many of the
specific needs for each application, it primarily focuses on the techniques required to analyze intermittent or "bursty" RF signals.
