Flexible Configurations and Upgrades - Helping You Manage the Digital Transition
To help address the challenges of maintaining both legacy analog and emerging digital video technology during the digital transition, the WFM6100 and the WFM7000 Series offers an exceptionally broad range of options and upgrades.
Video monitoring, audio monitoring, and measurement options can be added to a previously purchased instrument with a field-installable upgrade. For example, you can purchase a WFM6100 configuration that only monitors composite analog and then add support for SD digital video when your facilities are in transition. If you anticipate a future transition to HD digital technology, you can purchase WFM7000 or WFM7100 configurations without HD support, and then add this capability when your needs change.
Figure 1. CaptureVu can compare captured data and live signal on multiple displays
CaptureVu - Much more than "freezing" a display
The CaptureVu capability on the WFM6100 and WFM7100 can capture and store the video data from an entire video frame and display this data on waveform, vector, gamut, and picture displays. Unlike "freeze" captures, you can compare the live signal to capture data in one kind of display (for example, a waveform display), and then make the same live-to-capture comparison in a different display (such as a vector or picture display)
In addition to user-initiated captures, the instrument can do a triggered capture that automatically acquires data on the occurrence of specific faults. Triggered capture is particularly useful for finding intermittent errors and in capturing data about fault conditions at remote sites.
With CaptureVu, you can store a video frame generated by one piece of equipment (for example, a camera) and use this as a reference to configure other equipment to have matching video characteristics. The data can also be stored on a USB memory device and transferred to another instrument.
Figure 2. Use FlexVu to create the multi-view display that best fits your needs
FlexVu Display Interface - Four Instruments in One
The WFM6000 and the WFM7000 Series models have an integrated, XGA-resolution display with the Tektronix FlexVu user interface. With FlexVu, you can combine separate monitoring and measurement displays four at a time, in almost any combination. Unlike instruments with pre-determined view combinations or more restricted choices, FlexVu lets you create a multi view display best suited to your specific needs and work practices.
Figure 3. Personalize the menu interface with MyMenu
MyMenu and Presets - Frequent tasks at your fingertips
All models offer the MyMenu capability that lets you create a special menu tailored to your particular needs. MyMenu helps streamline instrument operation by letting you place up to seven of your most frequently used functions in one handy on-screen menu.
Using presets, you can quickly configure the instrument for specific tasks or personal preferences. These instruments can store up to 20 presets organized into four groups. You can label the presets and preset groups for easy identification. Each preset can store a different MyMenu.
The presets and MyMenu data can be downloaded to an USB memory device and transferred to another instrument.
Waveform Displays - Quickly Verify and Adjust Critical Signal Parameters
Familiar video waveform displays can show digital video signals in RGB, YPbPr, YRGB, or composite formats with flat or low-pass filtering. Waveform displays of composite analog video signals can show NTSC and PAL signals with luma, chroma, and luma+chroma filtering. Signal components can be displayed in either parade or overlay mode, and in composite format displays with setup selection. The waveform display has several sweep rates and easy, touch-screen control of vertical gain and horizontal magnification to help you efficiently monitor and measure video waveform parameters. With FlexVu you can see four differently configured waveform displays of the same signal.
Vector, Lightning, and SCH Phase Displays - Accurately Control Color Parameters
The vector display offers user-selectable graticules, color targets (75% and 100%), and color axis. The patented Tektronix Lightning display shows luma and chroma amplitudes and lets 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.
Figure 4. Quickly detect Gamut errors using specialized displays
Tektronix-exclusive Gamut Displays - Efficiently Detect and Correct Gamut Problems
The patented Tektronix Split Diamond and Arrowhead gamut displays simplify the process of verifying gamut compliance. The Split Diamond display helps easily identify and correct RGB gamut errors in digital video signals. The Arrowhead display saves time in verifying the gamut compliance of the composite analog video signal generated from a digital video signal. With FlexVu you can simultaneously monitor both gamut displays to quickly gain complete confidence in content compliance throughout the delivery chain. Also, user-selectable gamut thresholds let you tailor these displays, and the associated gamut alarms, to your particular compliance standards.

Figure 5. Patented Tektronix Timing Display
Timing Display - Simplify Plant Timing
The patented Tektronix Timing display makes facility timing easy through a simple graphical representation which shows the relative timing of the input signal (the circle) versus the reference signal (the crosshair)
For proper timing, the circle is centered on the crosshair and changes color from red to green. The display also has numeric readouts of the timing difference relative to the reference signal, showing vertical timing as number of lines and horizontal time difference in µsec.
Figure 6. Picture Display with Closed Caption, Safe Area graticules and gamut brightups
Picture Displays - Quick Visual Conformation and Precision Content Adjustment
A full-color picture display shows the video content of the monitored input. The instrument can display the picture on the full-screen, or on up to four views in a multiple-view display. For different input formats, the picture display automatically adjusts to show the full image content.
The picture display can also show content advisory codes and decoded closed caption data (EIA608 formats) for easy verification of this critical ancillary data.
Editors can choose from several Safe Area graticules on the picture display to quickly verify correct placement of graphics, titles, or logos. Graticules choices include the Safe Action and Safe Title graticules defined in the SMPTE, ITU, and ARIB standards, plus custom, user-definable graticules. Using FlexVu, editors can see two or more pictures with different graticules to verify correct placement for different formats and standards.
You can also select "brightup' conditions that show the location of RGB or composite gamut errors on the picture display. Line and sample brightups show the location of the currently selected line or video data sample.
Figure 7. Alarms, status, quality logistics, and logging
Alarms, Quality Statistics, and Logging - Thorough and Fast Content Verification
All models offer a variety of displays for "status at a glance" signal monitoring and quick, thorough content verification.
Using the alarm status display, operators and technicians can quickly detect video faults including gamut, EDH, and CRC errors, SDI format problems, and many more. The instrument offers several alarm notification methods, including on-screen error icons, audible beep, ground-closure output, and SNMP traps.
For verifying and documenting content compliance, the Video Session display shows key status information on the signal plus quality statistics like errored seconds and percentage content with errors.
To support unattended monitoring, and to supply documentation for maintenance records or service level agreements, the instrument logs alarms and other key events (such as format changes). Log entries can be time-stamped with date, time-of-day, and time code reference (VITC, ATC or LTC).
All models also offer extensive ancillary data monitoring. This includes monitoring the presence of closed caption content formats defined by EIA608, EIA708, and ARIB standards
Audio Monitoring - Versatile Tools Help Confirm and Adjust Sound Quality
The WFM6100 and the WFM7000 series offers several options for monitoring both analog and digital audio.
Available on all models:
Option DS monitors digital audio, both embedded and AES/EBU inputs.
Option AD monitors analog audio formats and all the digital audio formats included in Option DS
Available on the WFM6100 and WFM7100:
Option DD monitors and decodes Dolby Digital audio (AC-3) plus the analog and digital audio formats included in Option AD.
Option DDE monitors and decodes Dolby E plus all the audio formats included in Option DD
Options DD and DDE automatically sense Dolby audio formats and place a status message in the appropriate audio bar, eliminating confusion about audio input formats. Dolby status displays offer in-depth review of decoded Dolby metadata.
All audio options have an audio bar display can display up to six audio bars for analog inputs, up to eight audio bars on AES/EBU inputs and embedded audio sources, and up to ten audio bars when decoding Dolby Digital and Dolby E formats.
Figure 8. Audio bars and Surround Sound displays
The audio options provide user-selectable scales, meter ballistics and audio level indicators. "In-bar" messages show status and fault conditions for each monitored audio channel, reducing the likelihood of an undetected audio problem.
Audio phase displays include phase correlation meters, a flexible Lissajous display (for any pair of channels), and a multiple-channel "Surround Sound" display that shows audio levels (weighted or un-weighted), total sound volume, phantom source locations, and the dominant sound position.

The Audio Session display shows audio error conditions (such as parity errors), highest true peak, and the number of detected, clips, mutes, over-levels and silences. User-specified threshold values determine over-level and silence conditions and the durations a potential audio problem must persist before the instrument generates an alarm.
In addition to monitoring audio inputs, these options can generate analog or digital audio outputs from the analog or AES/EBU audio inputs. They can also generate audio outputs from embedded audio in the video input, or by decoding Dolby audio inputs, including stereo down-mixes. A convenient front panel headphone connector lets you listen to any stereo audio output
Figure 9. 3-Eye, 20-Eye, and jitter waveform
SDI Signal Measurement and Data Analysis - Resolve the Most Challenging Problems
The WFM6100 and WFM7100 offers options for monitoring and measuring SDI signal parameters:
For basic SDI signal monitoring, Option EYE has Eye pattern displays, plus readouts of jitter and key cable parameters
For more complete SDI signal measurement, Option PHY has all the capabilities of the EYE option plus a jitter waveform display and automated Eye parameter measurements
On the WFM6100, Options EYE and PHY measure SD-SDI signal parameters. On the WFM7100, these options measure both SD-SDI and HD-SDI signal parameters.
Both EYE and PHY options can display Eye Patterns in 3-Eye, 10-Eye (SD-SDI), or 20-Eye (HD-SDI) mode. These displays include cursors to manually measure Eye parameters and user-selectable clock bandwidths to help isolate jitter components. Option PHY automatically measures Eye amplitude, rise-time and fall-time.
Both options use a phase demodulation technique with selectable filters to continuously monitor and measure the peak-to-peak amplitudes of timing and alignment jitter.
The phase demodulation approach helps better characterize the random and deterministic jitter in the input signal. An easy-to-interpret jitter gauge augments the numeric jitter readouts. The jitter waveform display available with Option PHY lets engineers examine signal jitter in greater detail.
An SDI signal status display summarizes key signal parameters. This includes signal strength, cable loss and estimated cable length based on the user-selected cable type. With FlexVu, you can simultaneous display timing and alignment jitter values, cable parameter measurements and different Eye Patterns to help quickly diagnose and resolve problems related to SDI timing jitter or cable attenuation.
To help efficiently detect and diagnose errors in digital video data, the WFM6100 and WFM7100 offer Option DAT, containing a color-coded data word display, logic waveforms of the video data, and a display of data words in user-specified ancillary data packets.
Figure 11. USB ports and Headphone Connector
Signal Inputs and Outputs, Peripherals, Communication - Convenient Interfaces for Video Systems
The digital video options (Options SD, HD, EYE, and PHY) have two SDI inputs and a switched output of the selected input signal. The analog video option (Option CPS) has two composite analog video inputs with passive loop-through outputs.
The instrument senses the input format and automatically configures the required settings. It will signal a format mismatch if the applied external reference format is not compatible with the input signal.
The audio options (Options DS, AD, DD, and DDE) have up to 16 AES/EBU input channels and up to 8 AES/EBU output channels. Those with support for analog audio have up to 12 analog audio inputs and up to 8 analog audio outputs. All audio options can output to the front-panel headphone port.
The front-panel USB port makes it easy to store captured data or instrument settings on a USB memory stick and transfer this information to another instrument.
All models have a 10/100Base-T Ethernet connection and offer remote access and control with a standard Web-browser. You can use this interface to download presets and error logs, or print the screen contents for easy record keeping.
For simple remote control, a ground-closure type remote interface can indicate alarm condition or execute instrument presets. An SNMP interface allows easy integration with network management software.
