The monitoring and measurement capabilities of the WVR7200 provide a comprehensive suite of options and configurations to suit a variety of applications. For monitoring applications Tektronix-patented gamut displays simplify colour adjustments for camera balancing and colour correction applications. Get information about the signal at a glance from the audio session and video session displays that assist in ensuring quality control of the image.
Tektronix provides an extensive audio toolset for monitoring analogue, digital AES/EBU and digital embedded within Option AD. Up to 16 channels of embedded audio can be monitored for bar levels, which allows the operator to quickly check audio signal levels. Lissajous, Surround Sound, and correlation meters show the interaction of the audio channels. For Dolby Digital (AC-3), Dolby Digital Plus and Dolby E, Option DPE adds the additional functionality to decode the Dolby stream with a comprehensive Dolby metadata decode and status display. To ensure Dolby E synchronization the guard band meter easily shows the start of the Dolby frame in relation to the video signal with user-defined limits.
Loudness is a critical audio measurement to make for each produced program and throughout the distribution chain. The WVR7200 includes a Loudness meter as part of Option AD or DPE, with short and infinite audio loudness measurements to ITU-R BS.1770-2 standard. Preset configurations are defined to meet ATSC A/85, EBU R128, and ARIB TR-B32 to suit the specific requirements of these standards. For detailed analysis of loudness a graphical plot provides a Loudness Session that can store up to 30 hours of data and can be downloaded for inclusion in documentation using a network connection or USB device.
A variety of ancillary data is now carried within the SDI signal, and the ANC data toolset of the WVR7200 can help monitor and troubleshoot problems within the signal chain. The Aux Data Status display provides a summary of critical ANC data such as closed captioning / subtitling, AFD, and time code. The ANC Data Inspector allows the user to quickly verify the presence of ANC data within the signal and the Datalist display allows inspection of the data line by line, sample by sample.
For measurement of the physical layer the WVR7200 includes high-precision eye and jitter displays that provide automated measurements of amplitude, rise/fall times, overshoot/undershoot, and timing or alignment jitter. The measurement functions of the WVR7200 also include options for AV Delay and Stereoscopic 3D Monitoring, making the WVR7200 an ideal choice for monitoring and measurement applications.
