Tektronix offers video and audio monitoring in a single rack

Test and measurement vendor Tektronix has designed a new rasterizer unit to include video and audio signal monitoring and quality control in a series of one-rack unit devices called the WVR600 series. For broadcasters with limited space and complex monitoring needs, the WVR600 series provides a cost-effective analog and digital signal monitoring solution.

The WVR600 series provides a user-configurable display and full support for traditional waveform display.

The WVR600 series includes support for standard definition SDI (WVR610A) and hybrid SD-SDI/composite (WVR611A) in a compact 1 RU. Each device in the line offers a tiled, high-resolution (1024 x 786) output to external displays and the ability to monitor both analog and digital signals in an all-digital architecture. It includes two optional composite inputs for analog audio, digital AES/EBU audio (including embedded audio files), or both. Waveform, vector, gamut, audio, status and picture monitor displays can be combined with line select, gain and magnification in nearly unlimited combinations.

The WVR600 series also incorporates Tektronix’ new FlexVu display multi-screen viewing feature, enabling users to view four waveforms of a particular signal simultaneously.

The WVR600 series provides a user-configurable display and full support for traditional waveform display. Both overlay and parade (one display after another). Features also include the company's familiar gamut monitoring that includes Arrowhead, Diamond and Split Diamond display configurations. It also includes support for both level and phase relationship, and gain, sweep and magnification controls.

Similar yet different from a standard waveform monitor, a rasterizer displays signals much like a video or computer monitor, whereas a traditional waveform displays are drawn from point-to-point in a vector mode. Rasterizers have the advantage of supporting color, like the WVR600 series does, and are able connect to a variety of external displays for added flexibility. Some rasterizers have standard video rate outputs to allow routing around a facility, while others, like the WVR600 series, use higher resolution computer displays (VGA/SVGA/XGA).

An alarm status screen can be displayed providing up-to-the-moment information on the state of each condition currently being monitored by the instrument. To support unattended monitoring applications, as well as provide documentation for service level agreements, the WVR600 maintains a log of all monitored alarms, time stamped with Vertical Interval Time Code (VITC) or Longitudinal Time Code (LTC) and time of day references.
