Price Guide (Inc GST): POA

Tektronix, the market leader in broadcast video test, monitoring and analysis solutions, has further enhanced its family of waveform monitors and rasterizers with critical audio loudness capability.  

Building upon its current loudness measurement capability, Tektronix now offers WFM6000/7000 and WVR6000/7000 Series customers new firmware and software upgrades that adhere to the ITU-R BS.1770-1/1771 specifications.  The upgrades include capabilities such as an Audio Loudness Meter, an Audio Loudness Session Display and the industry’s first audio loudness monitoring of Dolby Digital Plus audio.

There are two new key elements to our Audio Loudness offering:

1.  Audio Loudness Meter which provides indications of loudness levels and will be provided as a free firmware/software upgrade for WFM7k/6k and WVR7k/6k series products equipped with an audio option.

The key features of the Audio Loudness Monitoring are:
  • Measure audio loudness and true peak of combination of discrete audio channels as well as Dolby Digital, Dolby Digital Plus, and Dolby E audio program as per ITU-R BS.1770-1 / 1771 and ATSC A/85 recommendations
