Extended Digital Analysis Capabilities
ANC Data Inspector and CaptureVu provide detailed content analysis.
The new ANC Data Inspector (available on Option DAT) provides an industry-leading solution to help broadcasters easily and accurately ensure that all required ANC data is present and correctly configured through an intuitive ANC data display.
In contrast to existing solutions, the ANC Data Inspector enables operators to easily and quickly ensure that the ANC 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 tile can display different CEA608 Closed Caption and individual Teletext subtitles or pages.
CaptureVu, standard on the WFM6120, captures the data of a video frame to recreate any trace display and analyze its digital structure. Captured data can be downloaded through the USB port or through the Ethernet port.
Aux Status Display.
The Auxiliary Data Status display decodes Ancillary data such as Active Format Description (AFD), Video Index Aspect Ratio, WSS, and ARIB information.
Aux Data Status provides summary information on a variety of metadata such as CEA608 Closed Caption, Broadcast Flag/CGMS, Teletext, Time Code, AFD (Active Format Description), Video Index Aspect Ratio, and Wide Screen Signalling.
Today there is a wide variety 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 automatic graticule display is available for the picture display of the waveform monitor along with the binary data and text description.
See and Solve™ with Tektronix Displays
See and Solve™ displays detect and address problems quickly and efficiently.
FlexVu – The display that adapts to your work practices.
Tektronix See and Solve™ displays simplify video monitoring tasks such as calibration, error detection, and content correction allowing users to detect errors at a glance and troubleshoot them efficiently.
Specialized session and status displays provide summarized, yet comprehensive reports of conditions and measurements of content parameters. The powerful Error Log is configurable and provides detailed reports for up to 10,000 events which can be downloaded using a web browser. Alarms can also activate ground closures and SNMP traps, simplifying centralized monitoring of multiple programs.
The FlexVu four-tile display provides maximum flexibility to increase your productivity.
Unlike instruments with predetermined view combinations or limited choices, FlexVu lets you create a multiview display tailored to your specific needs and work practices.
Each tile can be configured to enable easy signal analysis such as multiple alarm and status screens, different Safe Area Graticules and cursors on each tile, and more.
Tektronix displays offer the sharpest CRT-like trace quality for clear waveform monitoring without pixelation distortions.
The patented Tektronix 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 on analog and 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.
Monitoring Tools for Optimum Sound Quality
Comprehensive Audio Monitoring.
For precise audio measurements, the WFM Series provides high-quality digital filtering and oversampling fully compliant with ITU-R BS.1770-3 and 1771.
For easy monitoring, the WFM audio option provides format auto-detection and flexible mapping of audio inputs to analog or digital audio outputs for connection to external devices.
The Surround Sound1 display, the most comprehensive audio analyzer, provides intuitive graphical representation of the channels' interaction in a system. The Bars display provides indicators for faults, audio levels, and Dolby format information. The flexible Lissajous display allows the selection of any two audio channels.
Specialized audio displays provide deeper insight of the signal. The audio session display summarizes levels, faults, and number of active bits for each channel. The user can select from three loudness filters; flat, A-weighted, and RLB (BS.1770-3). These instruments also feature Audio Control Packet Data and Channel Status displays.

Top Reliability on Physical Layer Measurements
Tektronix is the technological leader for eye/jitter measurement solutions.
Options EYE and PHY provide unique capabilities such as reporting jitter levels above 1 UI and jitter filters from 10 Hz to 100 kHz for SD-SDI.
An easy-to-interpret gauge provides direct readout for jitter measurements. The user can configure timing and alignment readouts to be displayed simultaneously to effectively isolate the sources of jitter.
The SDI Signal Status display summarizes key signal parameters such as signal strength, cable loss, and estimated cable length measurements.
Additionally, Option PHY provides Tektronix-exclusive jitter waveform displays to view the jitter related to line and field rates. This option automatically measures eye amplitude, rise/fall time, and overshoot/undershoot.
With FlexVu, you can simultaneously display timing 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 be used to more easily view the eye opening of the physical layer signal.
Physical Layer options provide precise measurements for video signals.
Facility Timing Made Easy
Timing and Lightning displays simplify timing tasks.
Audio/Video synchronization is an important challenge in the processing of video materials.
Option AVD displays the A/V delay on a graphical bar indicator. The measurement readout gives facility engineers the tool to ensure system integrity and facilitate A/V delay compliance.
This option 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 waveform monitor.
The patented Tektronix Timing display makes facility timing easy through a simple graphical representation which shows the relative timing of the input signal and reference signal on an X-Y axis.
The Lightning display shows luma and chroma amplitudes and helps you verify component timing using a color bar header signal. The SCH Phase display helps quickly verify this critical timing parameter of composite analog video signals.
