  • Step 1 – Coverage Test Drive

SAM-CV 1000 - Test Drive

SAM-CV 1000 RF Measurement

RF Measurement

During a test drive SAM-CV 1000 collects the RF measurements from one or more RF input as well as the GPS data for the current position. With one SAM-CV 1000  the network operator is able to get the coverage for several DVB-T/-T2 channels or for several DVB-T2 PLPs with just one single test drive.

All relevant RF parameter measurements of all processed DVB-T/-T2 RF channels and/or all DVB-T2 PLPs along with simultaneously aggregated geographical coordinates and further meta data are stored into XML based data files.

  • Step 2 – Coverage Data Analysis

SAM-CV 1000 Map Display

Map Display

The recorded data can be evaluated and displayed in a map by using Google Earth ™. For every measurement point a place mark gets painted onto the map, whose color indicates whether the particular RF parameter value is OK or close to the configured WARNING or ERROR thresholds. Threshold profiles for various purposes, e.g. in-door/out-door reception, can be defined and can then be applied to the data evaluation in the map window with a single mouse click.

Green place marks mean the particular RF parameter is “well within the thresholds”. Green going toward yellow means the particular RF parameter comes close to the warning threshold, but is still OK. Yellow going toward red means the particular RF parameter crossed the warning threshold and comes closer to the error threshold, but still didn’t cross it. Red means that the particular RF parameter crossed the error threshold.

This visualization makes it very simple to evaluate the recorded RF parameters visually over the complete region.
