• Fading applications with convience: Universal Protocol Tester R&S ® CRTU-G

  The Universal Protocol Tester R&S ® CRTU-G [1 ] covers various markets,from development through to conformance test and type approval. Its outstanding hardware concept also satisfies users who place the highest of demands on flexibility and configurability.In combination with the Baseband Fading Simulator R&S ® ABFS [2 ], the generation of fading applications becomes child ’s play without the need for any additional equipment such as RF combiners.

• Expanding WCDMA receiver tests: Universal Radio Communication Tester R&S ® CMU 200

  Mobile user equipment for applications with high data rates such as video transmission or Internet browsing is equipped with complex receivers.The R&S ®-K 65 to -K69 (3GPP FDD) WCDMA software packages for the R&S ® CMU 200 [*] provide new measurement components for receiver tests that help to examine these sophisticated receivers in UMTS mobile phones and to assess their quality.This article covers the BER measurement with asymmetric data rates in the DUT transmitter and receiver, explains UMTS-specific blind transport format detection (BTFD) tests and presents measurements that the DUT itself carries out (UE measurement reports).

• Solutions not only for (E)GPRS mobile radio development: Universal Radio Communication Tester R&S ® CMU 200

  Modern mobile radio systems have become so complex that even development departments have difficulty keeping track of all system details. A mobile radio tester is therefore expected not only to provide universal and highly accurate test technology but also to support development engineers in their challenging tasks.

• Measurements on cdma2000 base stations: Application note and software free of charge

  The cdma2000 standard is being used in more and more countries, particularly in Asia. For base station measurements, the 3GPP2 C.S0010 standard ("Recommended Minimum Performance Standards for cdma2000 Spread Spectrum Base Stations") specifies a total of 15 transmitter and 14 receiver measurements.These are subdivided into various test scenarios (e.g.different fading profiles). The tests require signal generators and analyzers with various options plus a variety of settings, which are extensive in some cases. [...]

• Test of HSDPA base stations: Analyzers R&S ® FSP /FSU /FSQ

  The new R&S ®FS-K 74 application firmware expands the test functionality of the Spectrum Analyzers R&S ®FSP and R&S ®FSU and the Signal Analyzer R&S ®FSQ to include code domain analysis of HSDPA signals for WCDMA 3GPP FDD - at the highest speed currently available on the market.

• Test of TD-SCDMA base stations: Analyzers R&S ® FSP /FSU /FSQ

  The new R&S ® FS-K76 application firmware enhances the test functionality of the Spectrum Analyzers R&S ® FSP and R&S ® FSU and the Signal Analyzer R&S ®FSQ. For the first time worldwide, R&S ® FS-K 76 now makes it possible to perform TD-SCDMA code domain measurements with a spectrum analyzer. TD-SCDMA (time division synchronized code division multiple access) is a new standard mainly endorsed by China. R&S ® FS-K 76 enables the peak code domain power and modulation accuracy of TD-SCDMA signals to be measured in the same manner as for WCDMA and cdma2000 signals.

• Easy replacement of HP 856x and HP 859x spectrum analyzers in T&M systems: Analyzers R&S ® FSP /FSU /FSQ

  Anyone who has ever developed a certified T & M system knows the problem: What can be done once the instruments get older and spare parts are no longer available? With older controllers, a modern, PC-based solution is usually the answer. But when it comes to T &M instruments, e.g.the HP 856x or HP 859x family of spectrum analyzers, there are no successors with a compatible remote control command set. Yet without these, you cannot avoid expensive modifications and renewed certification of the control programs. A solution is found in the Rohde &Schwarz spectrum and signal analyzers of the R&S ® FSP, R&S ® FSU and R&S ® FSQ families (FIG), which provide an expanded command set compatible with the HP 856x and HP 859x.
