Reliable network coverage is a key requirement for the successful implementation of new technologies and applications. To support network operators in meeting this requirement, Rohde & Schwarz developed the new Radio Network Analyzers R&S TSML-x in addition to its universal Radio Network Analyzer R&S TSMU. The compact, high-performance R&S TSML analyzers are suitable for use in different networks irrespective of the technology employed as well as for broadband applications in the frequency range from 80 MHz up to 4 GHz. Whether you need to carry out power measurements in GSM, WCDMA or TETRA networks, perform GSM network scans or PN scans in CDMA2000 or WCDMA networks, or rather conduct handover analyses the four cascadable instruments offer maximum flexibility to suit whatever requirement you may have.
In many cases, test mobile phones are used to optimize network coverage. These are, however, subject to limitations with respect to measurement speed and accuracy. The new radio network analyzers from Rohde & Schwarz offer far better performance in these areas. Moreover, analyzers of the R&S TSML-x family are capable of scanning several networks in parallel, since they are not limited to a specific SIM card or the characteristics of a specific mobile phone. The interface via which users can control their R&S TSML-x analyzers and read results comes with a description and a demo application. This enables the use of customized software, opening up additional applications and providing maximum flexibility. The instruments can of course also be run with the R&S ROMES software established on the market.
The R&S TSML-CW analyzer for RF power measurements performs radio-network-independent CW and RF level measurements on modulated and unmodulated carriers triggered by time or distance pulses. The wide frequency range of 80 MHz to 4 GHz ensures high flexibility. Whether broadband, TV bands, WiMAX, TETRA, GSM (all bands) or WCDMA (bands I to IX) the R&S TSML CW covers all desired bands and technologies. Featuring a measurement rate of 20 channels/s (GSM) or a resolution of 10 cm at 180 km/h (GSM R), the R&S TSML-CW is also impressive in terms of speed.
The R&S TSML-G GSM network scanner from Rohde & Schwarz decodes system information such as CI, MNC, LAC, MCC and BSIC for all GSM bands. The instrument features very high speed, offering a measurement rate of 80 channels/s including demodulation and decoding. This makes the R&S TSML G an ideal solution for the fast optimization of GSM, GPRS and EDGE networks. Roaming problems or interferences as may occur with various network operators are easily detected. In addition, a monitoring function is available for the GSM bands.
The R&S TSML-C and R&S TSML-W PN scanners measure the basic RF parameters of CDMA2000 (R&S TSML-C) and WCDMA networks (R&S TSML W). The user can thus automatically analyze the RF power, timing and quality parameters of all PN codes of the signal. The R&S TSML-C frequency range covers all CDMA2000 bands; plus, it offers a high measurement rate of 5 Hz. The RF receiver used in the R&S TSML-W makes further receivers for different regions superfluous, as it covers all WCDMA frequency bands (I to IX). The measurement rate of the R&S TSML-W is 10 Hz. Both analyzers perform parallel measurements on six carriers and can therefore be used for benchmark applications. Moreover, both analyzers are equipped with 512 rake receivers.
To analyze intersystem handover, for example, you can combine an R&S TSML-W and an R&S TSML-G. The R&S ROMES software enables online analysis of handovers within 3G networks and between 2G and 3G networks, as required.
All analyzers of the R&S TSML-x family are extremely lightweight (1.5 kg) and highly compact. They can also be integrated into a 19-inch rack. Their low power consumption (8 W) makes them ideal for mobile use. An IEEE 1394 (FireWire) interface enables high-speed data transfer to the PC. The analyzers also feature a VICOM user interface, via which customized software solutions can be implemented.
The Radio Network Analyzers R&S TSML-CW, R&S TSML-G, R&S TSML-C and R&S TSML-W are now available from Rohde & Schwarz.
