Unmatched Measurement and Monitoring Performance for Content Creation and Content Distribution
 

Most Advanced Physical Layer Measurement Solutions

The WFM8300 and WFM8200 high-performance waveform monitors offer the most comprehensive physical-layer signal measurements for engineers. When equipped with Option 3G and relevant physical-layer options for each model, the WFM8300 and WFM8200 can perform 3G-SDI eye pattern display, jitter measurements, and cable length measurements (Option PHY for WFM8300 or Option EYE or PHY3 for WFM8200). Options PHY and EYE provide unique capabilities such as reporting jitter levels above 1 UI and providing various jitter filters from 10 Hz to 100 kHz for SD/HD/3G-SDI signals. An easy-to-interpret gauge provides direct readout for jitter measurements. Users can configure timing jitter and alignment jitter readouts to be displayed simultaneously to effectively isolate the sources of jitter. The SDI Status display summarizes key signal parameters such as signal strength, cable loss, and estimated cable length measurements.

With FlexVu™, users can simultaneously display timing jitter and alignment jitter values, cable parameter measurements, and display different eye patterns to help quickly diagnose and resolve problems related to SDI timing jitter or cable attenuation. The infinite persistence mode of the waveform monitor can also be used to more easily view the eye opening of the physical-layer signal.

In addition, the WFM8300 (with Option PHY) and WFM8200 (with Option PHY3) can also perform automated eye amplitude, automated rise/fall time, automated overshoot/undershoot measurements, and provide jitter waveform display to view jitter related to line and field rates. All these capabilities help broadcasters and network operators detect and diagnose signal quality problems quickly and efficiently. WFM8300 (with Option PHY) and WFM8200 (with Option GEN) also include multirate HD/SD-SDI and 3G-SDI (with Option 3G) color bar and pathological signal generation capabilities to provide engineers with a simple signal source for quick signal path verification during system and/or equipment setup and troubleshooting.

Superior Data Analysis Capabilities for Engineers and Operators

The new ANC Data Inspector (standard on WFM8300 and available on WFM8200 with Option DAT) provides an industry-leading solution to help broadcasters easily and accurately ensure that all required VANC data is present and correctly configured through an intuitive ANC data display.

In contrast to other solutions, the ANC Data Inspector enables operators to easily and quickly ensure that the VANC data is present and free of errors. When errors are detected, engineers are quickly guided to a more detailed view of the data packet content for further analysis.

With FlexVu™, each picture display tile can display different CEA708/608 Closed Caption and individual Teletext subtitles. Teletext subtitle pages can be decoded in either WST or OP47 format.

The Auxiliary Data Status display (standard on both the WFM8300 and WFM8200) provides summary information on Active Format Description (AFD) per SMPTE 2016, Video Index Aspect Ratio, Wide Screen Signaling (WSS), V-Chip, TSID, CGMS-A, Broadcast Flag, CEA708/608 Closed Caption, Teletext, and Time Code information.

Today there is a wide array of metadata that provides information to a variety of equipment through the processing chain. Monitoring of this metadata is critical to ensure that the processing equipment correctly handles the signal. For instance, correct format of the AFD ensures that the aspect ratio on the display is correctly formatted and the automated AFD graticule is available for the picture display of the WFM8300 and WFM8200 along with the binary data and text description for easy monitoring.

The WFM8300 and WFM8200 can also monitor Dolby metadata embedded in the Vertical Ancillary (VANC) data space per SMPTE 2020.

The Datalist display, available as standard on the WFM8300 and available as part of Option DAT on the WFM8200, provides detailed information on the actual data values in HD/SD-SDI and 3G-SDI (with Option 3G) input signals. Users can easily use this display to locate protocol errors in the input signals.

The right side of the display shows the data values in hexadecimal, decimal, or binary format and uses the following color coding for easy identification of data types and errors:

• Green – Active video data
• Blue – Data in horizontal or vertical blanking intervals
• White – EAV, SAV, and other reserved words
• Yellow – Data outside nominally allowed values
• Red – Data with illegal values

The left side of display shows un-interpolated digital values plotted against sample numbers as a digital waveform. You can configure this unique display in either Video mode or Data mode.

In Video mode, the display shows the Y, Cb, Cr values aligned temporally, but offset vertically. Like the waveform display, you can configure the display to show 1, 2, or all 3 components.

Full-featured Simultaneous Input Monitoring Boost Versatility

The Simultaneous Input Monitoring (SIM) capability standard on the WFM8300 and available with Option SIM on the WFM8200 takes multiformat monitoring to a new level. This capability helps operational staff quickly determine if a video quality problem existed in the input signal or arose in their facility. It enables engineering staff to quickly detect, diagnose, and resolve technical problems introduced in a piece of video equipment by comparing the input and output signals at each point in the chain. This feature is also especially helpful when checking for transparency during format conversion.

FlexVu™ enables flexible and intuitive configuration of displays from two monitored inputs. User can display simultaneous fault detection, status reporting, alarm generation, and error logging. SIM is ideal for transmission monitoring of simultaneous HD and SD programs. It is also ideal for monitoring stereoscopic 3D content in production and post production applications by simultaneously monitoring the Left Eye signal and the Right Eye signal.

SyncVu™ is used in conjunction with SIM mode for 3D applications when input A is used for the Left Eye and input B is used for the Right Eye (Note: SIM is included as part of Option 3D on WFM8200). When SyncVu is enabled, the Left and Right Tile displays are synchronized, so that if a Picture Tile is selected for Tile 1, automatically Tile 2 displays a Picture Tile in exactly the same mode as Tile 1. This enables the user to quickly configure the instrument identically for Left and Right Eye 3D monitoring.

Multiple Input mode can be used to monitor up to 4 SDI inputs simultaneously when in Full Screen mode (4-input mode requires Option 2SDI). This type of display is ideal for camera balance applications where the user wishes to check the video level across multiple inputs. This Multiple Input mode is available within Waveform, Vector, Lightning, Diamond, Arrowhead, and Spearhead (with Option PROD) display modes, allowing for the comparison of video inputs across a wide variety of these displays.

3D Measurement and Monitoring

The 3D measurements and displays are standard on the WFM8300 and available as Option 3D on the WFM8200. A 3D image is comprised of a Left Eye and Right Eye view feed as two separate HD-SDI signals or combined within a 3G Level B format. Additionally, a 3D signal can be carried within a single SDI signal as a left and right image Side by Side, Top/Bottom, or Field Interlace. Within the instrument a variety of different 3D monitoring modes are available to assist the user in determining the difference between the Left Eye and Right Eye views. From this disparity difference between the two left and right images the depth of an object within the image can be determined.

3D Left and Right Eye images showing Green/Magenta Anaglyph and Checkerboard display using SIM mode.

For monitoring purposes a variety of displays can be set up within the Picture mode:

• Difference Map Display – A subtraction of the two luma video signals L-R or R-L to produce a grayscale difference map image to see the difference between left and right images.
• Red/Cyan Anaglyph Display – The left image is shown in red and the right image is shown in cyan, with identical left and right objects shown in monochrome. This allows the user to isolate differences between objects and gauge the depth of the object within the image.
• Green/Magenta Anaglyph Display – The left image is shown in green and the right image is shown in magenta, with identical left and right objects shown in monochrome. If an object appears in magenta and then green this indicates that the object is coming out from the screen plane. Similarly if the object appears in green and then magenta the object is behind the screen plane.
• Checkerboard Display – This picture display shows a block of the image from the left eye and then the next block shows the image from the right eye in a 16×9 checkerboard pattern. This helps the user compare the levels and color of the signal between the left and right images.

These modes help the user compare the disparity between the left and right images and can assist in interpreting the depth of the objects within the image.

For measurement of the depth of an object within the image a Disparity Grid can be overlaid over the picture with a horizontal disparity between 1 to 15% of screen width and a vertical disparity of 50%, 25%, or 10% that can be selected by the user. The horizontal and vertical position controls allow the Disparity Grid to be moved around within the picture display to gauge the depth of objects within the image.

A set of Disparity Cursors are also available for precise measurement of horizontal disparity of an object between the Left and Right Eye images. Readout is given of the pixel difference between the cursors and the percentage of disparity of an object.

Tektronix displays offer the sharpest CRT-like trace quality for clear waveform and vector monitoring without pixelation distortions. The familiar video waveform display can show SD/HD/3G-SDI signals in RGB, YPbPr, YRGB, or composite formats. Signal components can be displayed in either Parade or Overlay mode. For composite analog video, NTSC and PAL signals can be displayed with luma, chroma, and luma+chroma filtering. The vector display offers user-selectable graticules, color targets (75% or 100%), and color axis.

The Tektronix-patented Diamond, Split Diamond, and Arrowhead gamut displays simplify the process of verifying gamut compliance.

The Diamond and Split Diamond displays help easily identify and correct RGB gamut errors in digital video signals. The Arrowhead display saves time in verifying composite gamut compliance for digital video signals.

User-selectable gamut thresholds let you tailor these displays and the associated gamut alarms to your particular compliance standards.

You can also select bright-up conditions to see the location of gamut errors on the picture display.

The WFM8300 and WFM8200 also feature new optional advanced color gamut monitoring capabilities including the Tektronix-patented Luma Qualified Vector (LQV™) display and Spearhead display which, when used in conjunction with Tektronix proprietary Diamond and Split Diamond gamut displays, provide the most comprehensive color gamut monitoring tools available for precise color gamut adjustments (Option PROD).

The picture display can simultaneously detect and decode CEA708/608 Closed Caption. Teletext subtitle pages can also be decoded in either 625 formats or using OP47 Ancillary data. Flexible Safe Area Graticules allow for quick placement of graphics, titles, or logos. Using FlexVu™, users can see two or more pictures with different graticules.

The CaptureVu^® feature on the WFM8300 and WFM8200 allows users to capture, store, and download the data of a video frame to recreate displays and compare the live signal to captured data for easy troubleshooting of intermittent errors or for analyzing fault conditions at remote sites.

Facility Timing Made Easy

Audio/Video synchronization is an important challenge in the processing of video signals. The WFM8300 or WFM8200 with Option AVD displays the A/V delay on a graphical bar indicator. The measurement readout gives facility engineers the necessary tools to ensure system integrity and facilitate A/V delay compliance. This feature provides out-of-service measurement of A/V delay for analog or digital audio and video formats. A TG700 is required to generate the SDI signal which contains the audio and video sequence that can be distributed through the system and measured by the WFM8300 or WFM8200 with Option AVD.

The Tektronix-patented SMPTE RP168 compliant Timing display makes facility timing easy through a simple graphical representation which shows the relative timing of the input signal and the reference signal (or a saved offset reference) on an X-Y axis.

The Lightning display shows luma and chroma amplitudes and helps users verify component timing using a color bar signal. The Tektronix-patented Bowtie display (standard on both the WFM8300 and WFM8200) complements the timing measurement capability of the Lightning display. Using a special Bowtie test signal in component format, this display helps make precise and accurate measurements of interchannel amplitude and timing. The SCH Phase display helps quickly verify this critical timing parameter of composite analog video signals.
