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 4-tile display provides maximum flexibility to increase your productivity.

Unlike instruments with pre-determined view combinations or limited choices, FlexVu lets you create a multi-view 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 a 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 picture display can detect and decode EIA608/708 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.

CaptureVu, on the WFM7120 and WFM6120, allows to capture, store and download the data of a video frame to re-create displays and compare the live signal to capture data for easy troubleshooting of intermittent errors or for analyzing fault conditions at remote sites.

Simultaneous Input Display Boosts Monitoring Versatility

Option SIM takes multi-format monitoring to a new level.

This capability helps operation staff quickly determine if a video quality problem existed in the input signal, or arose in their facility. It lets engineering staffs quickly detect, diagnose, and resolve technical problems introduced by a piece of video equipment by quickly comparing the input and output signals at each point of a chain.

This feature is especially helpful when checking for transparency during format conversion.

FlexVu enables flexible and intuitive configuration of displays from two monitored inputs.

With WFM7120 option SIM, you can display simultaneous fault detection, status reporting, alarm generation and error logging.

The patented Tektronix Timing display can be used for each source to time each input relative to the reference or measure the timing between each input.

Audio and video signals can be displayed independently for each input.

Top Reliability on Physical Layer Measurements

Tektronix is the technological leader for Eye/Jitter measurement solutions.

Option JIT enables jitter measurement for 3 Gb/s video with jitter waveforms and readings with alignment, timing and filters from 10 Hz to 100 kHz.

Options EYE and PHY provide unique capabilities such as reporting jitter levels above 1 UI and jitter filters from 10 Hz to 100 kHz.

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.

Monitoring Tools for Optimum Sound Quality

For precise audio measurements, the WFM Series provides high-quality digital filtering and over-sampling fully compliant with ITU-R BS.1770 and 1771.

For easy monitoring, the WFM audio options provide format auto-detection and flexible mapping of audio inputs to analog or digital audio outputs for connection to external devices.

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). These instruments also feature Audio Control Packet Data and Channel Status displays.

The Dolby Status Display (in option DDE) gives an in-depth view of integrated or VANC metadata and Dolby A/V timing and synchronization.

Facility Timing Made Easy

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 insure 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 typically used to generate the audio to video sequence to pass through the facility and measure the A/V timing at various locations.

The patented Tektronix Timing display makes facility timing easy through a simple graphical representation which shows the relative timing of the input signal reference signal on an X-Y axis. The display also has numeric readouts of the timing difference relative to the reference, showing vertical timing as number of lines and horizontal differences in μsec.

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.
