DAB/DAB+ Advanced Monitoring Probe
EdgeProbe Advanced DAB/DAB+
The ideal tool for accurate & cost-effective monitoring of the quality actually delivered to all points of DAB/DAB+ networks.
Applications
- 24/7 Monitoring and Maintenance of the SFN networks: TX transmission and SFN Overlapping Reception Areas
- Generation of Service Availability reports for Service Level Agreements
- Plan and improve the network configuration by identifying global trends
Benefits
- Standalone, easy to use and configure, fast deployment, SNMP compatible
- Reduce TX sites maintenance cost by anticipating and identifying issues
- Increase customer satisfaction by detecting & preventing network degradations before your customers do
- Remotely accessible, compatible with low bandwidth control networks (GPRS/3G/4G)
- Low power consumption 25W
Combined with a Network Monitoring System or not, the EdgeProbe Advanced provides a powerful broadcast network alert & diagnosis tool allowing Digital Radio network operators to monitor global trends and anticipate potential failures.
EdgeProbe Advanced is able to monitor DAB/DAB+ signals at transmitter outputs as well as in the reception areas, through its RF inputs (up to 4 in 1RU).
DAB/DAB+ monitoring through the RF inputs (up to 4 in 1RU)
Signal Level, MER, SNR, FIC BER, MSC BER (Pre/Post, per sub-channel)
Compatible Band III VHF (168 to 240 MHz)
Channel RF Spectrum and Constellation display
RF Shoulder Upper/Lower measurement
Mode I, II support; automatic detection
Local analog audio output: via front panel controls
SFN monitoring at TX or Reception area
On TX site:
- RF signal time synchronization; detects up to +/- 1.2 seconds time drift
In Reception area (SFN overlapping area):
- Channel Impulse Response (Echoes), with advanced Echo Pattern mode: better echo in error identification even if the main (stongest) echo suffers changes; no time shift if the main echo disappears
- TII detection (Main/Sub ID)
DAB Transport monitoring
Ensemble Service Plan: check ensemble structure and alarm Service ID presence
Service information (SI)
32 GB of internal storage (up to 4 in 1RU)
Alarm logs & RF parameter trends up to 4 months
CSV format files. Available for download via web GUI or FTP connection (automation scripts)
Internal GNSS receiver (HW option)
Generates an internal 1PPS reference signal for SFN synchronization measurements – which is independent from the modulator’s reference signal
GPS & GLONASS support
Dual Power Supply (HW option)
One additional Power Supply can be installed on the equipment in order to ensure the power redundancy
