Features & Benefits

  • Comprehensive 8VSB confidence monitoring for ATSC broadcast networks. Includes monitoring of the symbol distribution waterfall chart and MER, BER and SNR measurements for continuous monitoring of signal quality
  • PSIP conformance and consistency checking, including Closed Caption (EIA608/708) and Regional Ratings Descriptor (RRT), allows broadcasters to determine the system is compliant with FCC regulations
  • Monitoring in accordance with A/78 enables filtering and display only of errors that require immediate attention
    • Transport Stream Off-Air (TOA), Program Off-Air (POA), Component Missing (CM), Quality of Service (QoS), Technically Nonconforming (TNC)
  • DPI monitoring allows analysis and diagnostics of "splice" advertising and other local content

Applications

  • The RFM300 is a powerful solution for monitoring ATSC transmitter sites and off-air monitoring, as well as contribution and distribution monitoring at local and national operation centers and headends

RFM300 Delivers Comprehensive DTV Monitoring

The RFM300 provides a complete solution for real-time DTV monitoring of MPEG transport streams. The comprehensive RF and PSIP confidence-monitoring capability provides a powerful and cost-effective solution for monitoring DTV transmitter sites, along with contribution and distribution feeds at local and national operation centers for FCC compliance.

The RFM300 delivers comprehensive RF 8VSB measurements which include symbol distribution waterfall chart, MER and PSIP analysis (includes an Electronic Program Guide). This can be combined with a single diagnostic option to provide enhanced diagnostic capability that includes detailed service logging, in-depth PCR analysis, triggered recording and template testing. The extended confidence-monitoring probes can be installed throughout the network and powerful diagnostic capability can be added to the key monitoring points where transport streams are manipulated.

When used together with VQNet™, facility and network-wide views allow engineers to sectionalize network problems.


FlexVuPlus™ configurable windows in ATSC mode.


Video and audio content monitoring to ensure QoE is maintained.


A/78 modes classify five distinct levels of importance. 


EPG View 


Advanced Timing Analysis including PTS-PCR for real-time buffer measurements to give indication of encoding and multiplexing errors.
