The WVR600 Series Rasterizers broaden the Tektronix line of waveform monitoring products by introducing support for SD-SDI (WVR610A) and hybrid SD-SDI/Composite (WVR611A) applications in a convenient 1 RU form factor. Analog, digital or embedded audio monitoring options can be selected for either instrument.
Powerful Display Flexibility - FlexVu™
To maximize application flexibility, a high-resolution, tiled display design lets users customize presentation of information for each operation they wish to perform. Waveform, vector, gamut, audio (optional), status and picture monitor displays can be combined with line select, gain and magnification in nearly unlimited combinations. These instruments offer a number of exclusive displays that speed and simplify the monitoring and measurement tasks, continuing the Tektronix tradition of measurement leadership.
Unprecedented Display Flexibility
The FlexVu display lets users combine information in ways that have never been available in any video monitoring product. Instead of making users cycle through preset displays to view the information they require, Tektronix has designed an optimal approach that offers complete flexibility.
Furthermore, any time you need a closer look at an individual display, just press the "Full Screen" button for a high-resolution 1024x768 presentation.
A content QA application demonstrates the display flexibility. The instrument is set up to display an RGB paraded waveform in one tile, a view of the white level at 5X gain in another, a view of the black level at 5X gain in a third tile and video session statistics summarizing the overall content quality in the remaining tile. Together this creates an information presentation never before available.
Quality of your content at a glance: Waveform parade, white and black levels and a full set of summary statistics.
After format conversion, problems in the horizontal blanking interval are often the first indication of non-compliant content. For example, by displaying a digitally magnified view of HBLANK, a traditional paraded waveform, a field sweep, and a composite representation of the component signal, all on a single display, these instruments offer an invaluable perspective on this critical part of your content.

Waveform Displays
A complete range of display options lets users choose between parade or overlay presentation of SDI signals in RGB, YPbPr, YRGB or composite formats. Full horizontal timing flexibility is provided with 1Line, 2Line, 1Field and 2Field sweep modes, with or without timing magnification. Both fixed and variable vertical gain are offered, each with the outstanding accuracy and repeatability that comes from a fully digital design.

High-performance composite waveforms are available in the WVR611A. Wide bandwidth and outstanding display quality combine to let users discern even the finest details. A variety of filtering options allows optimized presentation of information.
Vector Displays
Traditional component and composite vectors are offered, with selectable 75% and 100% targets. Each display automatically selects the appropriate graticule based on the input format.
The patented Tektronix Lightning display provides unique insight not available in traditional vector displays - allowing users to visualize both luma and chroma amplitudes, as well as quantify inter-channel timing, without taking the equipment out of service.

Gamut Displays
Monitoring for gamut compliance, traditionally a strength of Tektronix products, is expanded in the WVR610A and WVR611A products. The patented Tektronix Diamond display for monitoring RGB gamut compliance is augmented by the new Split Diamond display. These displays let the operator visualize whether the content is RGB gamut compliant with a single glance. Plus, they are designed to help isolate the out-of-gamut component just as easily.
For SDI component content that is destined for broadcast in composite systems, the unique Tektronix Arrowhead display can be used to monitor composite gamut compliance without the need for a separate encoder. Within this display, a separate upper and lower luma-only gamut limit can be applied. The power of the FlexVu display in the WVR600 Series lets you monitor the Diamond and Arrowhead displays simultaneously for complete confidence in content compliance throughout the delivery chain.

Each of these displays offers user-selectable gamut thresholds so operators can set monitoring limits appropriate to their specific operation. In addition, gamut monitoring is fully integrated with the powerful alarm logging and reporting capability of the WVR600 Series.
Audio Displays (Optional Capability)
Available in the WVR600 Series are a range of audio options that can add comprehensive audio monitoring capabilities for analog audio, digital audio or both.
Level bars display, or both bars and a Lissajous display, can be selected to provide monitoring for digital audio formats, embedded or externally input, up to 7.1 (or up to four stereo pairs), or for up to two sets of six balanced analog inputs. The level meters offer selectable meter ballistics and scaling. Analog audio scales can be set to dBu, DIN, Nordic, VU or IEEE PPM. Digital audio scales are available for dBFS and can be user configurable. These instruments have a set of two programmable levels designed to optimize detection of out-of-range conditions in analog signals, or in digital signals derived from analog sources. The over and silence settings augment digital clip and mute detection by letting users select levels to represent these conditions in the analog audio domain.

In addition to audio displays, a full range of audio error conditions can be selected for monitoring, including AES unlock, parity errors and checksum errors.
Status Displays
The WVR600 Series offer a variety of displays designed to show status at a glance, in addition to the status bar continually displayed at the bottom of the screen.
A comprehensive overview of the video content status is presented in the video session screen. Offering a time-based compilation of information, this screen is ideal for presenting evidence of compliance after content screening. Information on input format and session time is presented, along with statistics on Error Detection and Handling (EDH)/Cyclic Redundancy Check (CRC) errors and gamut errors. Information is presented in errored seconds, errored frames and percentage of total frames - together providing a unique quantitative insight to content quality.

When one of the audio options is installed, an audio session screen is available to confirm evidence of compliance. This screen records the highest true peak, as well as the number of mutes, clips, overs and silences during the session time.
An alarm status screen can also 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 system 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.
Timing Display
The patented Tektronix Timing display presents a unique timing comparison between a house reference signal and a digital or analog television signal, thus eliminating the ambiguity present in waveform monitor and vectorscope measurements when timing differences approach multiples of a field or a line. Timing difference is displayed numerically in terms of vertical and horizontal offset of the signal being timed to the house reference signal. In addition, an innovative graphic target icon clearly indicates the timing relationship over the full color frame, displaying gross error in terms of relative screen position.
Picture Monitor Display
For a qualitative view of the content, a full-color picture monitor is offered, which can be displayed either in a single tile or as a full-screen presentation. This display is compatible with all input formats and features automatic adjustment for aspect ratio and number of active lines.
Remote Operation
Powerful and flexible remote control features help users integrate these instruments into a variety of remote monitoring scenarios.
Using the built-in 10/100Base-T Ethernet port, users can remotely control every major feature of the instrument and view the display, as well as download the alarm log and print the screen contents for easy record keeping. This powerful Java application offers a variety of control options to suit individual preferences, and allows you to create and recall an unlimited number of instrument presets.
Where simplified interfacing is the dominant requirement, a ground-closure type remote interface provides access to recall of instrument presets and an alarm signal output. The ground-closure interface is ideal for use in master control scenarios or in outside broadcast applications.
