3GPP FDD and LTE Multicell and Multi-UE Scenarios with the R&S SMU200A Signal Generator

This application note describes how to set up 3GPP FDD and LTE multicell and multi-UE scenarios with the R&S®SMU200A with a focus on routing and leveling of the baseband signals. Furthermore, it describes in detail how to determine the correct AWGN settings, i.e. how to calculate the required signal-to-noise ratio for the various scenarios.

Head to Head: NI PXIe-5665 Versus Traditional Boxed Instruments

This paper discusses the setup details for the demo shown in this video Head to Head: NI 5665 vs. Traditional Boxed Instruments. The demo compares the performance and speed of the NI PXIe-5665 with the Agilent PXA. Rather than comparing the datasheet specifications of both instruments, this video compares the two instruments while performing real- world test scenarios.

Wideband 400W Pulsed Power GaN HEMT Amplifiers

RFMD has developed 400W pulsed output power GaN HEMT amplifiers operating over 2.9GHz to 3.5GHz band or 17% bandwidth. Under pulsed RF drive with 10% duty cycle and 100us pulse width, the amplifier delivers output power in the range of 401W to 446W over the band, with drain efficiency of 48% to 55% when biased at drain voltage of 65V.

Strategies for Signals Intelligence from Antennas to Analysis

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.

Calibration Basics and Best Practices

Individuals who view calibration as a necessary evil are not taking into account the bigger picture. Calibration is essential to improving a company's bottom line, by minimizing risk to product defects and recalls, and enhancing a reputation for consistent quality.

Noise Figure Measurement without a Noise Source on a Vector Network Analyzer

This application note describes the noise figure measurement using the R&S Vector Network Analyzers of the ZVA and ZVT series. It explains the concept of measuring noise figure without the need for a characterized noise source. Furthermore, it discusses different measurement applications and the respective setup and implications. Some examples guide through the instrument setups and show measurement results as well.

The Effective Number of Bits (ENOB) of my R&S Digital Oscilloscope

The effective number of bits (ENOB) is a way of quantifying the quality of an analog to digital conversion. A higher ENOB means that voltage levels recorded in an analog to digital conversion are more accurate. In an oscilloscope the ENOB is not just determined by the quality of the analog to digital converter but by the instrument as a whole. This application note explains how to measure the oscilloscope ENOB and shows results for the R&SâRTO for different settings.
