Reliable RF testing of GSM, GPRS and EDGE mobile phones: RF Test Systems R&S TS8950G / TS 8955G
Since the very beginning of GSM mobile radio, Rohde & Schwarz systems have been the de facto standard for conformance testing. Continuous extensions to the standard, additional frequency bands and shorter design phases pose new and higher demands to which Rohde & Schwarz responds with the RF Test Systems R&S TS8950G / TS 8955G. They support all GSM850 / 900 / 1800 /
1900 frequency bands in the circuit switched, GPRS and EGPRS connection modes and are easily upgraded to WCDMA.

Wide dynamic range for measuring adjacent channel power: Vector Signal Generator R&S SMIQ03HD
WCDMA base station amplifiers must feature excellent spectral purity and low intermodulation distortion to mini-mize interference in adjacent channels. Measuring these characteristics calls
for sources that are able to generate low-noise and low-distortion WCDMA test signals over a wide dynamic range. The R&S SMIQ03HD is designed especially for this purpose.

Fast and efficient - product documentation on CD-ROM:
Electronic publications are now a generally accepted standard for technical documentation. Compared to conventional print media, they offer the user a whole number of decisive advantages: faster location of information through integrated search functions and navigation aids as well as more up-to-date information thanks to simpler distribution. Moreover they are easier to deal with thanks to far less volume and weight. The new CD-ROM for the Univer-sal Radiocommunication Testers R&S CMU200/ 300 aims to combine all these features.

Evolution in power measurement - intelligent sensor technology: Power Meter R&S NRP
Microwave power meters are only as good as their sensors, which is why they were the focus of development for the new Power Meter Series R&S NRP. The sensors offer a dynamic range of up to 90 dB for modulated signals of any RF bandwidth, plus time gating, high measurement speed and low
measurement uncertainty. Whether used for digital mobile radio, wireless LANs, or classic applications:
these sensors set new standards in terms of versatility and accuracy.

Bandwidth and dynamic range for future systems and technologies: Signal Analyzers R&S FSQ
The R&S FSQ is fully in line with the trend towards systems with higher data rates (e.g. wireless LAN) and multicarrier signals. With an analysis bandwidth of 28 MHz, the instrument is well prepared for future technologies and systems, without compromising on dynamic range and easily
meeting the demands of all trans-mission standards. Using only complementary firmware applica-tions,
without hardware addons, the R&S FSQ is easily expanded into a multistandard or multicarrier analyzer.

Excellent dynamic range up to 26 GHz plus low measurement uncertainty: Spectrum Analyzer R&S FSU26
This new analyzer is an addition to the R&S FSU family. Excellent dynamic range and sensitivity plus
unique measurement functionality such as fast ACP in the time domain or channel filters are now also available for microwave applications. New functions that can be retrofitted to the analyzer family as firmware updates mean additional upgrading and improved dynamic range for ACP measurements.

Analyzing broadband FMCW signals at a keystroke: Spectrum Analyzers R3172 / R3182 from Advantest
FMCW signals have become popular for distance measurements in recent years in addition to classic pulsed radar signals. For this special and new measurement application, Advantest has developed an FM demodulation option for its Spectrum Analyzers R3172 and R3182, allowing demodulation of FMCW signals and examination of deviation and linearity.

Low-power transmitters for terrestrial digital TV: UHF Transmitter Family R&S SV7000
Terrestrial digital transmitter networks are currently being set up world-wide, initially with transmitters of the high-power or medium-power class. But there is also a need for low-power transmitters, for example to cover small urban areas and valleys or for closing coverage gaps. The UHF Transmitter Family R&S SV7000 is a compact and economical solution in such cases.

Measurements on MPEG2 and ATM signals - across all layers: MPEG2 / ATM Test Set R&S DVATM
The use of new transmission routes for MPEG2 calls for innovative and intelligent T &M concepts in the field of broadcasting and for telecommu-nication network operators. The new Test Set R&S DVATM provides interfaces for all layers involved as well as test signals and analysis functions. It is the world´s first unit to process both MPEG2 and ATM signals.

New coder for DVB-S/-DSNG and DVB-C standards: TV Test Transmitter R&S SFQ
With a new coder, the TV Test Transmitter R&S SFQ now supports the satellite standard DVB-S/-DSNG (digital satellite news gathering), which meets the growing demand for more transmission capacity. The coder also matches the DVB-S and DVB-C standards. It stands for a considerably extended symbol rate range and enhanced quality. The future-proofness of the universal R&S SFQ modulation platform and the versatile capabilities of the new coder are not at least due to high-efficiency Turbo coding.
