Tektronix has added enhancements to its waveform monitor and rasterizer product family which are intended to allow broadcasters, network operators, and content providers to detect and diagnose problems in video and audio quality and detect ancillary data problems.

The instruments offer simultaneous decoding and monitoring of CEA-708 and CEA-608 Closed Captioning data, meeting the latest FCC requirements.

The units now also support Active Format Description (AFD) and CGMS-A / Broadcast Flag data decoding and monitoring. For multi-channel audio, new Dolby E Guard Band monitoring provides user selectable thresholds and an intuitive bar meter display on the audio display so that operators can spot Dolby E audio problems.

Additionally, new black picture and patented frozen picture detection alarms help broadcasters and network operators detect, identify, and diagnose picture quality problems.
