Radio network analysers cover the full band

Analysers are suitable for use in different networks, irrespective of the technology employed, as well as for broadband applications in the frequency range from 80MHz to 4GHz.

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 and Schwarz has developed the new TSML-x series of radio network analysers in addition to its TSMU universal radio network analyser.

The compact, high-performance R and S TSML analysers are suitable for use in different networks irrespective of the technology employed as well as for broadband applications in the frequency range from 80MHz to 4GHz.

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 all requirements.

In many cases, test mobile phones are used to optimise network coverage.

These are, however, subject to limitations with respect to measurement speed and accuracy.

The new radio network analysers from Rohde and Schwarz offer far better performance in these areas.

Moreover, the R and S TSML-x family of analysers are capable of scanning several networks in parallel, as 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 and S TSML-x analysers and read results comes with a description and a demo application.

This enables the use of customised software, opening up additional applications and providing maximum flexibility.

The instruments can of course also be run using existing R and S Romes software.

The R and S TSML-CW analyser 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 80MHz to 4GHz ensures high flexibility.

Whether broadband, TV bands, WiMAX, Tetra, GSM (all bands) or WCDMA (bands I to IX) - the R and S TSML CW covers all desired bands and technologies.

Featuring a measurement rate of 20 channels per second (GSM) or a resolution of 10cm at 180km/h (GSM R), the R and S TSML-CW is also impressive in terms of speed.

The R and S TSML-G GSM network scanner from Rohde and 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 per second including demodulation and decoding.

This makes the R and S TSML G an ideal solution for the fast optimisation 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 and S TSML-C and R and S TSML-W PN scanners measure the basic RF parameters of CDMA2000 (R and S TSML-C) and WCDMA networks (R and S TSML W).

The user can thus automatically analyse the RF power, timing and quality parameters of all PN codes of the signal.

The R and S TSML-C frequency range covers all CDMA2000 bands; plus, it offers a high measurement rate of 5Hz.

The RF receiver used in the R and 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 and S TSML-W is 10Hz.

Both analysers perform parallel measurements on six carriers and can therefore be used for benchmark applications.

Moreover, both analysers are equipped with 512 rake receivers.

To analyse intersystem handover, for example, users can combine an R and S TSML-W and an R and S TSML-G.

The R and S Romes software enables online analysis of handovers within 3G networks and between 2G and 3G networks, as required.

Each analyser in the R and S TSML-x family is extremely lightweight (1.5kg) and highly compact.

They can also be integrated into a 19in rack.

Their low power consumption (8W) makes them ideal for mobile use.

An IEEE1394 (FireWire) interface enables high-speed data transfer to the PC.

The analysers also feature a Vicom user interface, via which customised software solutions can be implemented.
