Mobile measurement campaigns, driving or on foot, with GPS Positioning

• Real time measurements and display of RF and MPEG data analysis.
• Internal recording of measurement data on the NAVIGATOR DVB-T/H
• Automatic GPS position display and recording on the NAVIGATOR DVB-T/H equipment
• Manual position input capability (in case of no GPS reception or for additional notes)
• Mapping display of the measurement data. Click here to see an example of data display in Google Earth.

RF analysis

• RF parameters:  RF level, Carrier / Noise level
• Modulation parameters: MER, BER, PER
• Transmission parameters:  Cell ID, COFDM Mode, Guard interval, Constellation, Code rate

MPEG-T analysis

• TR 101290:
  • 1st priority: TS Sync Loss,Sync byte error, PAT error and PMT error
  • 2nd priority: Transport error ,CRC error ,PCR error, CAT error and PTS error
  • 3rd priority: NIT error, Unreferenced PID, SI repetition error,  SDT error*, EIT error*, RST error*
• Others:  PID and PMT bit rate*, PCR / Jitter*, FER and MFER.

Expert module* (optional)

The expert option decodes the SI/PSI tables and offers a clear tree representation.
Every time a table is present on a chosen PID, a bar is shown, with a width depending on its duration. Clicking on a bar, you see all the content in the selected table. You can thus double check that a parameter is compliant with the standards, or even find the source of a problem.
The table content can easily be exported as a XML file.

For DVB-H signals, the NAVIGATOR DVB-T/H offers many analysis features such as the burst displays, IP layer analysis and  comparison before and after correction.  DVB-H features are the following:

• MPEG2 layer analysis: Detection of all PIDs, detection of NULL packets, display of the DVB-H burst structure & Measurement of minimum and maximum delay for each DVB-H packet
• MPE Layer analysis:  Transport Packet(s) used, of all MPE/MPE-FEC sections and SI/PSI tables, clear text output of the SI/PSI tables with XML export possibility, display of the Delta-T information.
• IP layer analysis: Time reference of each received IP packet, source and Destination IP addresses and UDP ports

Campaign analysis with Goldeneye

• During a campaign, all the measurements (with their GPS position, if available) are logged and stored on the internal hard drive. The campaign file containing all this data can then be downloaded onto a PC and opened with Goldeneye.
• Goldeneye creates a geographical representation of the campaign with a different color for each level value (or field strength). Clicking on a point, you get information such as the modulation parameters and the speed.
• In the “Superimposed” tab, Goldeneye plots level curves. If the campaign contains data from several multiplexes, the curves can be superimposed for easy comparison.
• All details of each measurement point can be found in the measurement table (GPS position, C/N, MER, BER, PER, FER, MFER…)

Data filtering

You can choose the data you want to display in the geographical representation, filtering by:

• Distance (mean value on X meters).
• Cell ID
• Field strength value

In addition to the measurements, the NAVIGATOR DVB-T/H also logs the channel impulse response in the campaign file.

Clicking on a measurement point, you see the all the peaks that were detected, with their delay and level.

As an option, the Navigator DVB-T/H can record the transport stream while logging all the measurements. In Goldeneye, all the videos contained in the transport stream can thus be replayed with sound. When the video is playing, the cursor moves automatically (either on the geographical representation, or on the curves or even the measurement table), so that you see signal values associated.
With this option, you will qualify consequences of bad signal values directly on the video!

The measurement data can be exported to Google Earth, MapPoint, MapInfo, ATDI …
