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.

TETRA, the TErrestrial Trunked RAdio, is the professional mobile radio standard (PMR) used world wide by governmental safety and security authorities and organizations, as well as by private utilities from energy suppliers through to transport. Rohde & Schwarz provide test instruments idealy suited for both the development and production of TETRA base stations and user equipment, as well as for network planning, network coverage and quality of service, network monitoring and optimization, maintenance, and service. This Application Note shows examples for measurements with R&S instruments covering the entire range of TETRA test requirements.

We have a presentation available on our website that highlights Wireless InSite’s new capabilities. This short slideshow provides a more detailed look at the features the new release has to offer.

Post webinar white paper for attendees

Valpey Fisher has developed a series of products for Sync-E applications that specifically address both Jitter Transfer and Jitter Generation issues. VF products use a “crystal based” internal reference clock and an extremely narrow loop filter to produce the best performance solutions available in the industry today.

This white paper summarizes the technology options for supporting voice and short message service (SMS) in LTE, including circuit switched fallback (CSFB), SMS over SGs, and voice over LTE (VoLTE).

The aim of channel sounding is to characterize a radio channel by decomposing the radio propagation path into its individual multipath components. This application note provided by Neul describes how channel sounding can be performed using the R&S SMBV100A Vector Signal Generator and the R&S FSL Spectrum Analyzer. To illustrate the procedure reference is made to 8 MHz wide white space channels in the UK.

A common function present in most RF and Microwave systems is the electronically controlled variable attenuator. At Valpey Fisher Corporation, improvements to two key areas of the MCM approach have been made resulting in lower attenuation error.

Today, we have continually increasing needs to move, recover, and decode data in smaller bandwidths and shorter time slots with reduced errors. We also want to detect higher resolution information in a physical world of increasing electrical interference.

While Synchronous Optical Networks (SONET) have been widely adopted for use in long-haul applications, Ethernet is preferred in edge routers and access points due to its lower cost.
