Powerful confidence monitoring capability and deep diagnostic measurements are both combined into a single integrated solution. This enables cable operators to deliver superior QoS levels with reduced operational expenditure. Deployed at key network nodes, the Tektronix QAM-400A provides an intuitive and simplified presentation of video quality and diagnostic information. This supports the delivery of superior Quality of Service (QoS) levels in an increasingly complex broadcast environment. When used together with VQNet, facility and network-wide views allow engineers to sectionalize network problems.
The Tektronix QAM400A provides a complete solution for real-time transmission monitoring of MPEG Transport Streams over RF and ASI interfaces. Powerful confidence monitoring capability and deep diagnostic measurements are both combined into a single integrated solution. The confidence monitoring capability uniquely simplifies DTV monitoring with the FlexVu summary displays, which include video thumbnail and Electronic Program Guide (EPG) views. This empowers operational staff with the simplest information necessary to ensure their service is delivering above their defined thresholds for superior QoS.
The deep diagnostic option provides engineers with intelligent hierarchical views of network information, media, and data to support rapidly identifying the root cause of underlying service problems. This diagnostic monitoring option provides more in-depth analysis of the MPEG Transport Stream including recording capability and a comprehensive range of TS testing including TR 101 290, A/65, A/78, SCTE-142 compliance testing.
The Tektronix QAM 400A provides a single Transport Stream processor platform packaged in a 1 RU rackmount chassis to provide monitoring of a Transport Stream at data rates up to 155 Mb/s. The QAM interface allows the Tek QAM400-A to receive RF inputs and display key RF monitoring parameters including MER, BER, and Constellation displays before demodulating the signal to provide measurements on the health of the Transport Stream.
The channel polling capability for the Tektronix QAM400A probe combined with the RF interface allows up to 200 RF channels to be monitored in a repeating cyclic measurement process. Control and configuration of the polling is undertaken using flexible XML scripting. This polling ability makes a single Tektronix QAM400A probe a broader tool, monitoring large numbers of network points in a time-sampled measurement mode.
The remote user interface provides a highly simplified presentation of video quality and diagnostic information for operations and engineering teams. For a fully integrated monitoring solution, network management platforms are supported with a full set of APIs to support wider distributed network intelligence. This also includes video walls that can display up to the full transmitted resolution of the video stream for network operation centers.
Flexible and Upgradeable
The Tektronix QAM400A provides a highly scalable and field-upgradeable monitoring solution to tailor capital expenditure with operational growth. The extended confidence monitoring probes can be installed throughout the network and powerful diagnostic capability (Option DIAG) can be added to the key monitoring points where Transport Streams are manipulated.
- Triggered recording to be captured and rapidly analyzed in greater depth using powerful offline analysis tools such as the Tektronix MPEG Test System Stand-alone Software
- PSI/SI/PSIP/ARIB SI analysis and repetition rate graphing allows broadcasters to determine that the system information is present and correct in the Transport Stream
- Exception monitoring with simple automated template generation from reference streams. Template testing checks a number of key parameters to ensure that the Transport Stream has been constructed as the broadcaster intended. These parameters include the Transport Stream ID and Network ID, the number of programs in the multiplex, that each program has all of its components (Video, Audio, Data, Teletext, Subtitles), and Conditional Access (CA) status
- Bit rate testing determines whether PIDs, programs, services, or user-defined groups of PIDs are within user-definable limits to ensure correct multiplex operation. Tektronix-proprietary PID variability test gives indication of PID bit rate variation to assess effects of statistical multiplexing
- In-depth PCR analysis with graphical results views enable timing and jitter measurements to be made to ensure correct operation of the network
