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.

Sequencing of waveforms is a technique used to play back multiple test signals fast and flexibly using an arbitrary waveform generator (ARB). Multiple ARB waveforms can be combined to generate all kinds of test signals sequences. Switching from one waveform to the subsequent waveform in the sequence is instantaneous, which enables high-speed operation for production testing. This application note explains how to generate such signal sequences using vector signal generators from Rohde & Schwarz. The examples provided show the required instrument settings and possible fields of application for waveform sequencing.

Verification of baseband data is an important step in the early development phase of LTE/LTE-A-ready products. Comparison values for baseband data (test vectors) from other sources can be very useful in order to verify the correct implementation of the standard. Option K81 for the R&S®SMx200A vector signal generator offers sample data for LTE at the bit level. The reference data enables users to test their own implementation of the specification. The LTE bit stream verification program shown here uses data generated by this option and offers a (bitwise) comparison with bit streams generated for an LTE downlink signal. Therefore it demonstrates, how easy the option R&S SMx-K81 can be integrated into the simulation and design process during the development of LTE/LTE-A handsets or base stations.

Multiple antenna systems, known as MIMO systems, form an essential part of today’s wireless communications standards. The multi-antenna technology efficiently boosts the data throughput without requiring additional bandwidth or transmit power and has thus become a key technology. Rohde & Schwarz offers compact and versatile MIMO test solutions with realtime fading including simulation of channel correlations.This application note explains how to set up Rohde & Schwarz signal generators for 2x2, 4x2 and 2x4 MIMO tests with a focus on signal routing, synchronization of the generators, and leveling. Please note that there is a successor application note available: 1GP97. It explains how to use the R&S®SMW200A vector signal generator for testing higher order MIMO systems such as 3x3 and 4x4.
