Wireless testing in focus at Electronica

At this year's Electronica, Rohde and Schwarz will showcase a wide range of spectrum analysis products, accurate signal generators and network analysers.

Applications such as wireless networks for the Internet via WiMAX, pocket mobile TV and infotainment in the automotive sector are becoming increasingly more attractive for users, and manufacturers and network operators face ever more demanding challenges.

At this year's Electronica, Rohde and Schwarz will showcase a wide range of spectrum analysis products, accurate signal generators and network analysers, plus a complete T and M portfolio for HSDPA and HSUPA.

UMTS long term evolution (LTE), the next generation in mobile radio, is already waiting in the wings - with Rohde and Schwarz again at the forefront of developments.

The electronics company supports LXI, the standard for improved instrument networking in production, by offering a wide range of LXI-compatible instruments.

Moreover, Europe's largest supplier of transmitters provides T and M solutions for DVB-H - which is just one of many examples - and monitoring systems for verifying reliable network operation.

Network operators worldwide are currently upgrading their UMTS networks with high speed downlink packet access (HSDPA).

From 2007, high speed uplink packet access (HSUPA) will improve the performance of data transmission from mobile phones to basestations.

Rohde and Schwarz supports the introduction of HSDPA and HSUPA by providing a complete portfolio of T and M solutions, which allows chipsets, user equipment, basestations and networks to be thoroughly tested before new functions are put into operation.

But HSPA, as the common operation of HSDPA and HSUPA is referred to, is by no means the end of UMTS enhancement.

The planning phase for UMTS LTE, the next generation of mobile radio networks, is now underway.

And Rohde and Schwarz is again a key player.

The WiMAX Forum has selected Rohde and Schwarz as one of the manufacturers of radio conformance test testers (RCTT) in compliance with the IEEE802.16e 2005 mobile WiMAX standard.

Based on validated test cases, the R and S TS8970 test system serves as a reference solution for the certification of WiMAX end products.

It is based on the concept of the market-leading R and S TS8950GW 2G/3G RF conformance test system.

The R and S TS8970 is also suitable for R and D applications and precompliance testing.

The Rohde and Schwarz WiMAX radio conformance test systems are implemented with WiMAX OFDM/OFDMA T and M equipment, including the signal generators of the R and S SMx family - R and S SMU200A, R and S SMATE200A and R and S SMJ100A - plus the R and S FSQ and R and S FSL signal analysers.

The R and S ZVA40 from Rohde and Schwarz is a new high-end network analyser with a frequency range from 10MHz to 40GHz.

Featuring a worldwide unparalleled output power of typically greater than 18dBm, a dynamic range of typically greater than 150dB and high measurement speed of 3.5us per test point, the R and S ZVA40 is the ideal tool for comprehensive measurements in microwave applications.

In R and D, this includes tests on filters, mixers and amplifiers, measurements on wavers for chip manufacturers, plus antenna measurements in radar/satellite applications.

With the R and S FSUP, Rohde and Schwarz offers for the first time an instrument specially designed for characterising RF signal sources and in particular for measuring phase noise.

The R and S FSUP incorporates the company's many years of experience in developing high-quality spectrum analysers and low-noise oscillators and synthesisers.

It is the only instrument in the world that combines a spectrum analyser and a phase noise tester up to 8, 26.5 or 50GHz.

Users will profit from simpler and more flexible test setups at a considerably lower price.

Rohde and Schwarz has expanded the frequency range of its analogue high-end R and S SMA100A vector signal generator.

The instrument can now be used for applications up to 3GHz - and optionally 6GHz - in labs, production and service.

Equipped with the option R and S SMA-K25, the R and S SMA100A can even generate VOR/ILS signals for tests on radio navigation receivers.

The signal generator offers excellent signal quality, short setting times and a compact design.

The R and S ESU from Rohde and Schwarz is a new family of CISPR16-1-1-compliant EMI test receivers that meet all civil and military standards for electromagnetic interference measurements.

A new FFT-based test method considerably speeds up measurements.

The time-domain scan allows users to perform overview measurements more than 100 times faster than with existing EMI test receivers.

The instrument also features comprehensive test functions such as a complete set of parallel detectors including the new CISPR-RMS detector, RF scan, IF analysis and numerous report functions.

The R and S ESU is available in three models with the frequency ranges 20Hz to 8, 26.5 and 40GHz.

The high-end R and S SMU200A vector signal generator and the other members of the R and S SMx family, the R and S SMATE200A and the R and S SMJ100A, meet the Class C specifications defined by the LXI standard.

The signal generators are the second product group from Rohde and Schwarz to offer LXI compatibility.

Also the R and S FSQ, R and S FSU, R and S FSP and R and S FSL spectrum analysers are Class C certified.

The portable R and S FSL spectrum analyser and the R and S SMATE200A vector signal generator will be showcased at the LXI consortium's booth at Electronica.

Rohde and Schwarz equips digital transmitter networks worldwide with TV and audio transmitters and is the leading supplier in this field.

By developing transmitters to meet the different standards and ranges, the company makes a key contribution to full-coverage digital TV transmission.

In this field, the electronics specialist has a unique competitive edge with its many years of experience in mobile radio and expertise in broadcasting.

This year, special focus will be placed on network monitoring to ensure reliable transmission operation.

The extensive scope of products includes the R and S ETX-T monitoring receiver for single frequency network monitoring, the new R and S ETL TV analyser platform as well as audio and TV transmitters for a wide range of standards and output power.

New options complement the successfully established R and S DVM family, providing RF and IP interfaces.

ISDB-T coder rounds out the portfolio of digital TV standards for development and test platforms The successful R and S SFU TV test platform from Rohde and Schwarz generates test signals for all important digital TV standards worldwide.

Equipped with the new ISDB-T coder option, the R and S SFU is the only test transmitter to combine all major standards, DVB-H, T-DMB, ISDB-T, DMB-TH and MediaFlo, on a single platform.

Scenarios with occupied adjacent channels can also be simulated.

Another option provided by Rohde and Schwarz is used for testing digital short-wave transmission (Digital Radio Mondiale).
