Receiver tests DVB-T networks on the run

The new R and S TSM-DVB diversity test receiver has been designed for mobile coverage measurements in DVB-T networks.

The new R and S TSM-DVB diversity test receiver has been designed for mobile coverage measurements in DVB-T networks To date, broadcasters have been able to perform stationary measurements but mobile measurements are also necessary - especially in digital networks

To meet this need, this handy instrument from Rohde and Schwarz combines with the R and S Romes coverage measurement software to provide information about transmitter signal quality while operating from a moving vehicle.

In addition, coverage and potential error sources can be clearly displayed on a notebook, quickly and economically.

Network coverage in digital TV networks is normally measured in accordance with the CCIR guidelines.

This entails setting up a 10m-high antenna at a test station, and so involves enormous effort and a lot of personnel.

In addition, digital networks require other coverage measurement methods, especially reception tests while the vehicle is moving.

The R and S TSM-DVB diversity test receiver meets these requirements.

During mobile measurement, it provides quick and reliable measurement values even if the test vehicle reaches speeds up to 100km/h.

The test system supports all DVB-T modes including the hierarchical modes across all bandwidths of 6, 7 and 8MHz.

The test instrument is equipped with two antenna inputs and two demodulation channels.

It runs from a 12V power supply, and so can be connected to a vehicle power system.

A PC or a notebook equipped with an RS232C interface and Windows XP Professional is all that is needed to evaluate measurements.

This means that the data can be gathered during a simple drive and subsequently analysed by specialists.

The R and S TSM-DVB supports measurement parameters such as RF level, modulation error ratio (MER), packet error ratio (PER), bit error ratio (BER) in accordance with Reed-Solomon and C/(N+i) as well as several status indicators (AGC locked, carrier locked, MPEG sync locked etc) or information about the transport signal (DVB-T mode, code rate etc).

The DVB-T diversity test receiver and coverage measurement software are now available from Rohde and Schwarz. Request a free brochure from Rohde and Schwarz ...
