The WFM700 Series of Multi Format Waveform Monitors offers the monitoring
capabilities needed in the production, post-production, distribution and
transmission of high definition (HD) and standard definition (SD) digital video
content.For mixed HD/SD environments, the multi-format WFM700A gives
you the tools you need to perform operational monitoring tasks like checking
signal validity and content quality, setting levels, and verifying signal paths.
The WFM700HD offers an HD-only version of these same capabilities. The
WFM700M offers all the capabilities of the WFM700A plus the digital analysis
capabilities important in the design, installation, and maintenance of digital
video systems, including eye diagram with automated measurements, jitter, and
data measurements for both HD and SD formats. With available digital audio
monitoring support, you can expand the capabilities of any WFM700 configuration
to monitor both digital video and audio in a single instrument.
These products combine the best of traditional waveform monitors with the
measurement accuracy, repeatability, and stability achievable with fully digital
technology. Their modular design lets you purchase the capability you need
now and add capabilities later as your requirements change. Backed by
Tektronix innovation, service, and support these modular, multiformat, fully
digital waveform monitors lower your cost of ownership while offering powerful
tools for monitoring digital video and audio signals Tektronix-exclusive Color Gamut Monitoring
Problems with production and operational equipment can introduce illegal colors
in the digital video signal, i.e. colors that fall outside established gamut
limits. Every member of the WFM700 Series has the following Tektronix
patented gamut monitoring displays:
- Diamond and Split Diamond - monitoring for RGB gamut compliance
- Arrowhead - monitoring for composite gamut compliance including luma
+ chroma and separate luma limit checking
With these specialized displays you can significantly reduce the time and
effort needed to perform this critical quality control task:
Often, digital video in component format is converted into NTSC or PAL composite
video format for transmission. Due to differences in component and
composite color spaces, video signals that fall within legal RGB color space may
not convert into signals that fall within a legal composite gamut.
The Arrowhead Display helps you quickly detect this type of color gamut
error, without the need for a separate composite encoder. To form the
Arrowhead display, the WFM700 transforms the component signal into an NTSC or
PAL composite signal representation and plots the luminance component of this
signal vertically against the chrominance component plotted horizontally.
Component signal values that correspond to out-of-gamut NTSC or PAL composite
signal values will lie outside the legal region shown on the Arrowhead display.
| You can adjust the thresholds used to define out-of-gamut conditions in the
Arrowhead display, tailoring the monitor's operation to fit your specific
requirements. The Arrowhead display has adjustable luma+chroma limits and
luma-only limits. Each allows user-defined upper and lower limits.
You can easily assess luma-only and luma+chroma compliance all within the
Arrowhead display. |

Familiar Waveform Monitoring Displays and Controls |
| |
|
| All WFM700 models offer familiar waveform displays. You can view digital
video signal components in either an RGB, YRGB, YPbPr color space, displayed in
parade or overlay mode. The YRGB color space combines the Y luminance
signal with the RGB component signals to give you benefits from both traditional
color spaces. In addition to these digital waveform displays, the WFM700 products can also
display a familiar composite representation of an SDI digital signal.
Every WFM700 model offers a rich set of familiar waveform display controls
including:
- 1-line, 2-line, 1-field, and 2-field sweep selections
- Line and Field Selects
- Flat and low-pass filtering
- 1x, 5x, 10x and variable gain settings
- 0% and 7.5% setup levels in the composite waveform representation
- Offset and aligned chroma settings in YPbPr color space
- Horizontal Magnification
- Selectable graticules including mV, IRE, and % scales
|

When used in 2-line sweep mode, the magnify feature will automatically
configure the instrument for optimal viewing of the horizontal blanking interval
on any SD or HD digital signal, eliminating the need for tedious,
trial-and-error adjustment
Tradition and Innovation in Monitoring Color Amplitude and Timing
Complementing these full-featured waveform displays, every WFM700 product offers
two specialized displays for monitoring the color information in digital video
signals
- The traditional Vector display for Monitoring PbPr color amplitude
- The Tektronix-patented Lightning display for monitoring luma and
chroma amplitudes and interchannel timing
| The Vector Display gives you a choice of representations, either component
graticule or composite graticule. The composite representation is
independent of the input signal colorimetry and gives the best indication of hue
shift. The component representation allows comparisons with equipment
having similar Vector Display representations. |
 
WFM700 Vector Display w/
Composite Graticule (compass rose) |
Selecting the composite graticule will show the color vector with the
traditional compass rose graticule. You can also choose to display the I
and Q color axes. The Tektronix-exclusive Lightning Display combines chrominance and luminance
information in a unique approach that helps you quickly detect and isolate
amplitude and timing problems in these signal components. Most
importantly, you can use a standard color bar signal to make these measurements.
You do not need to use special test signals. Only the Lightning display
gives you the ability to use readily available signals for making these critical
measurements, saving you both time and resources.
| The Lightning display is
especially useful in detecting and isolating interchannel timing problems.
Bowing of traces in the upper half of the display represents a timing problem
between Y and Pb while bowing in the lower half of the display represents timing
errors between Y and Pr. Calibrated graticule marks on the display help
you quantify these timing errors. |
 
WFM700 Lightning Display |
| |
|
You can set either 75% or 100% color bar targets on both the Vector and
Lightning display, or use the gain settings to normalize signal amplitudes.
In the Lightning display you can use the magnification settings to expand the
display scale for better viewing of the graticule marks.Automatic Detection of a Wide Range of Signal Formats
All WFM700 models have two terminating inputs for serial digital signals in
either SMPTE 292M format (WFM700HD, WFM700A, and WFM700M) or SMPTE 259M format
(WFM700A and WFM700M). The following table shows the supported signal formats:

*1 ITU-R BT.601 defines sampling for SD serial digital video per SMPTE
259M and ITU-R BT.656
*2 These segmented-frame format signals are detected as their corresponding
interlace format.
The monitor will automatically detect the signal format and establish the
appropriate settings for the various displays.
Every WFM700 model will also automatically detect the colorimetry of an HD
input signal, or you can manually select either ITU-R BT.709-2 or SMPTE 240M
All models accept an external reference signal for synchronization. You
can let the instrument automatically detect the external reference signal format
or manually select any of the following formats: NTSC, PAL, 1080i (50Hz,
59.94Hz, 60Hz), 1080p (23.98Hz, 24Hz), or 720p (59.94Hz)
"Status-at-a-Glance" Video Session Display
In addition to detecting a wide range of video signal characteristics, the
WFM700 waveform monitors offer valuable status and error reporting capabilities,
like the unique video session display. This display summarizes a variety
of statistics relevant to video content health and standards compliance,
including:
- Signal format and colorimetry
- Stuck bits indicator
- Presence or absence of ancillary data, including embedded audio,
closed caption data, or time codes
- Presence or absence of color gamut errors
- CRC values
- Errored seconds, errored fields, and % errored fields statistics
| The comprehensive summary available on the Video Session screen offers singular
insight into video signal quality over time including the percentage of total
content in error. It gives you a powerful tool for verifying video content
quality, especially valuable in supplying documentation for contractual or
business arrangements based on content quality. |
 
WFM700 Video Session Display |
Timing Reference and Auxiliary Data Monitoring
Every WFM700 Series product can detect information contained in the horizontal
and vertical synchronization intervals in the digital video, including:
- Start-of-Active-Video (SAV) and End-of-Active-Video (EAV)
- Error detection and reporting per SMPTE RP165 for standard definition
and SMPTE 292M for high definition
- Presence of closed caption information in accordance with EIA608 and, if
presence, decode and display the data on picture display
- Presence of closed caption information embedded in accordance with
EIA708 and ARIB B37 standards
- Ancillary Time Code (ATC) and Vertical Interval Time Code (VITC) values
- Presence of V-chip data and, if presence, the decoded rating
information
- Presence of ARIB STD-B39, ARIB STD-B3, ARIB TR-B22, and ARIB TR-B23
| Depending on your preference, WFM700 waveform monitors can either show the
SAV and EAV in waveform display or strip out this data prior to display. The Ancillary Data Display helps you view information contained in any ancillary
data packet by specifying the appropriate first data identifier (DID) and
secondary data identifier (SDID). All WFM700 Series waveform monitors can
display the data as a table of data words in hex format. The display can
also show information on data block and count, packet type, and checksums.
Every WFM700 Series product can detect the presence of closed caption data that
confirms to EIA608, EIA708, and ARIB B37 standard. For EIA608 format, all
WFM700 models can decode and display the closed caption data on picture
display with the actual line number containing these closed caption data.
User-adjustable Alarms and Event Logging
Further enhancing the capability available with the Video Session Display, all
WFM700 Series instruments can report and log a wide range of alarm conditions,
including:
- Input signal or external references signal missing or format mismatch
- Color gamut errors
- EAV/SAV missing or mismatch with line number
- SAV placement error
- CRC and EDH errors, code word violations, or field and line length
errors
- Ancillary data and Closed Caption present/absent errors, parity errors,
or checksum errors
You can adjust the thresholds used in detecting color gamut errors to
customize alarm reporting to your requirements.
No single alarm signal mechanism works for all facilities. Consequently,
every WFM700 waveform monitor lets you chose any of the following alarm
reporting methods:
- Audible beep
- On-screen icon or message
- Output on remote control port
- Event log entry
- SNMP trap
With a simple, push-button style user interface, you can configure the
waveform monitor to use any combination of these alarm-reporting mechanisms.
You can select different combinations for different alarms. Every WFM700 model maintains an event log with each entry stamped with the
time-of-day the event occurred. You can also configure event logging to
time stamp events with a VITC value.
Recording each individual event
separately can fill the event log quickly. To address this, the even
classifies entries as:
- Single Shot - one isolated occurrence
- Continuous - uninterrupted sequence of occurrences
- Intermittent - interrupted sequence of closely spaced occurrences
The event log stores a continuous event sequence as two entries marking the
beginning and ending of the sequence, saving space and increasing the time span
of the log. When storing intermittent events you can choose between two
logging modes:
- Log for resolution - Log intermittent events as separate entries,
giving you information needed to determine when the individual events
occurred
- Log for duration - Log for a longer time period by combining
intermittent events into a single log entry
By offering more sophisticated logging, the WFM700 Series lets you tailor
event logging to help you troubleshoot challenging operational failures, or meet
any reporting requirements specified in service level agreements. |

incorrectly positioned video content
- Up to 42 stored presets
- Print screen capability, context sensitive on-line help, and
complete instrument diagnostics
| The LCD display effectively uses color to help you analyze waveforms. A
simple, soft key menu structure uses touch screen control to avoid complex
setup, configuration, and control operation. Touch-screen control also
simplifies the front panel layout, creating a clean design with a large display.
Context-specific assignment of the general-purpose knob makes it easy to adjust
cursors, navigate through menus, and enter numeric values. |
  WFM700 Front Panel |
With a color display, WFM700 monitors can show a full-screen version of the
picture content in the monitored video signal. In addition to the
full-screen view, all WFM700 models can display a thumbnail version of the
picture on the Waveform, Vector, Lighting, Gamut, and data displays to help you
easily correlate signal characteristics with actual picture content.
The all-digital design of the WFM700 Series offers improved performance and
convenience in measuring waveform parameters. Electronic graticules let
you chose the best reference scale for a measurement. Digital cursors
accurately measure voltage and time deltas in all standard and magnified sweeps.
On-screen readouts and icons overlaid on the display inform you of signal
parameters and instrument settings or conditions, including:
Selected input, input format, colorimetry, and displayed waveform
component
Sweep, gain, and magnification settings
Line, sample, and field selections
Cursor Readings
Errors and Alarm Conditions
Every WFM700 waveform monitor saves the instrument state when powered down and
automatically restores this state when powered up. In addition, you can
configure up to 42 presets to set up common configurations at the touch of a
button.Taken together, the user interface features and display modes just
described create a flexible, intuitive and feature-rich environment you will
find easy to learn and easy to use.

Powerful Digital Video Waveform Measurement Available
For in-depth technical measurement of digital video signals, you need
additional capabilities. For making highly precise inter-channel amplitude
and timing measurements, every WFM700 model offers the familiar Bowtie display.
The WFM700M offers more comprehensive measurement capability, adding the
following displays to those offered on the WFM700A and WFM700HD:
- Data Display
- Eye Pattern Display with Automated Measurements
- Jitter Display
| The Bowtie Display adds to the timing measurement capability available in the
Lightning Display. Using a special Bowtie test signal in component format,
this display helps you make precise and accurate measurements of inter-channel
amplitude and timing. The left bowtie shows the amplitude and timing
relationship between the 1st and 2nd components in the test signal, while the
right bowtie shows these relationships between the 1st and 3rd components.
An inter-channel amplitude problem widens the signal at the center null position
in the bowtie. An inter-channel timing problem shifts this center null
position. |
 
WFM700 Bowtie display |
The Data Display available on the WFM700M gives you detailed information on the
actual data values in the video signals. You can use this display to
locate protocol errors or view ancillary data.
The right side of the display shows the data values in either hexadecimal,
decimal, or binary format and uses the following color coding for easy
identification of data types and error:
- Green - Active Video Data
- Gray - 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 number as a digital waveform. You can configure this display in
either video mode or data mode.
In video mode, the display shows the Y, Cb, Cr values aligned temporarily,
but offset vertically. Like the waveform display, you can configure the
display to show 1,2 or all 3 components.
For SD signals, data mode shows the data in the same sequence as it occurs in
the SDI signal, i.e. Y,Cb,Y', Cr where Y is the co-sited luma sample Y' is the
isolated luma sample. For HD signals, data mode splits the data into a Y
channel and a mutiplexed Cb, Cr channel, again to match the data orientation in
the SDI signal.
| You can display a thumbnail picture view in the data display, with cursor
overlays showing the current line and sample. Using the WFM700M Eye Pattern Display, you can view and measure the amplitude,
rise time, aberrations, and jitter of the both SD and HD serial digital signals.
The automated Eye measurements feature includes a histogram of the Eye sample
amplitude values that gives you another aid for understanding the
characteristics of the SDI signal. The 3-Eye display shows jitter
uncorrelated to the parallel word length. To view jitter characteristics
correlated to the parallel word you can select either the 10-Eye (SD) or 20-Eye
(HD) display. Clock recovery bandwidth adjustable to 10Hz, 100Hz, and 1
kHz helps you isolate the jitter components of interest. |
 
WFM700 Data display
 
WFM700 Eye Pattern display |

|
| In Jitter Display mode, the WFM700M demodulates the signal jitter, displays a
trace of video-correlated jitter vs. time, and measures peak to peak time jitter
in the active display. To isolate timing and alignment jitter components you can
select on of four high-pass filters with 10Hz, 1kHz, 10kHz, and 100kHz cutoff
frequencies, respectively. When placed in Line Select mode, the WFM700M
will measure the jitter of the selected line, giving you greater precision than
waveform monitors that only measure field jitter. The WFM700M also makes
the jitter demodulator output available on an external connector so you can
attach an oscilloscope or spectrum analyzer for further analysis. |
  WFM700 Jitter Mode display
|
Using the digital signal processing capabilities available in the all-digital
WFM700 Series, the WFM700M makes these critical measurements with a high degree
of accuracy, stability, and repeatability - the measurement performance you
would expect from Tektronix.
The automated Eye measurements include amplitude,
rise time, fall time, rise overshoot, fall overshoot, and a histogram of the Eye
sample amplitude values. In Jitter Display mode, the WFM700M demodulates
the signal jitter, displays a trace of video-correlated jitter vs. time, and
measures peak to peak time jitter in the active display. Digital Audio Monitoring Available on All Models
WFM700 Series digital audio monitoring and measurement features include:
- Monitoring of up to 16 embedded digital audio channels
- 4 AES/EBU audio inputs/outputs for monitoring up to 8 non-embedded
audio channels, or production up to 8 channels of de-embedded audio
output
- Support for multi-channel digital audio in 5.1 and 7.1 formats
- Audio Level Bar display of 2,4,6, or 8 audio channels with true
peak, PPM, and Extended VU meter ballistics and selectable scaling
- Single-axis Phase Correlation Meter showing the phase relationship
between signals on an audio channel pair.
- Flexible Lissajous display showing the phase relationship between
channels, with X/Y or Sound Stage (L/R) axis orientation and automatic
gain control
- Surround Sound Display for 5.1 multi channel digital audio format
with total volume, center volume, phantom source, and dominant sound
indicator as well as Ls and Rs correlation meter
Surround Sound Display helps you more precisely mix, master, edit, and verify
5.1 multi channel digital audio. The visual representation of the sound
image complements your auditory experience.
The display shows the audio level balance among the left (L), right (R),
left-surround (Ls), and right-surround (Rs) channels on the ruled scales
radiating from the center. A vertical bar between the L and R channels
shows the center (C) channel audio level
The polygon formed by connecting the level indicator endpoints shows the
total sound volume formed by the L,R,Ls, and Rs channels. This connecting
line will bend away from the center if the two signals have a positive
correlation, will bend towards the center if the signals have a negative
correlation, and will not bend if the signals have no correlation. In
addition to this total volume indicator, the display has a separate center
volume indicator by connecting the ends of the L, C, and R channel level by
straight lines.
Phantom source indicators (PSIs) located on each side of the display show the
location of potential phantom sound sources formed by adjacent channels.
Audio monitoring support adds several alarm conditions to the list of video
alarms described earlier, including detection of:
- Audio CRC errors
- Clip, mute, over, and silence conditions
- Audio Parity Errors
- Embedded Audio Absence and AES audio unlock
You can set the thresholds that trigger alarms on over and silence
conditions. This feature is ideally suited for monitoring digital audio
derived from analog audio sources. For example, due to the digitization of
audio hum, these signals do not typically contain the all-zero samples that
trigger a mute alarm. In this case, you can use the adjustable silence
alarm to detect loss of audio program.
Like the session display used to monitor video signals, all WFM700 models
with audio monitoring capability offer an audio session screen that lets you
quickly check the health of any digital audio channels and track key audio
signal parameters.
Key Fields Include:
- Highest true peak, highest uninterpolated peak, and highest bar reading
- Sample rate and active bits
- The number of clips, mutes, over's, and silences
- Invalid samples
- Detected receiver errors
| Like the Video Session display, the Audio Session Display gives you a powerful
tool for verifying and documenting content quality. In the multi-mode display
of a WFM700 waveform monitor with audio monitoring capability, you can combine
the Audio Level Bar and Phase Correlation Meter Display, the Lissajous display,
Surround Sound Display, the Audio Channel Status display or the Audio Session
Display with any of the displays already available in multi-mode. |
 
WFM700 Audio Session display |
Adding audio monitoring capability to a WFM700 waveform monitor gives you a
powerful, space-efficient, and cost effective solution for monitoring and
measuring your digital video and audio signals.
Multiple Inputs/Outputs for Easy System Integration
In addition to the inputs and outputs described earlier, every WFM700 model
has the following connections:
- VGA output for viewing the LCD display on a detached VGA monitor
- Analog component video picture monitor outputs
- VGA picture monitor output that follows the component picture monitor
output for viewing the picture on an inexpensive VGA display
- Looping inputs for bi-level and tri-level sync
- One switched SDI output that follows the selected input
- An SD SDI picture monitor output
For the component video picture monitor output, you can select signal format (RGB,
Y'p'bP'r) and HD colorimetry (ITU-R BT.709, SMPTE 240M). You can also
select picture brightups for RGB and composite gamut errors as well as
Line/Sample brightups for use in Line Select mode operation to indicate the
monitored line and sample on the external picture monitor.
| |
|
| With these connections, you have a wide range of choices for
integrating the WFM700 waveform monitor into your facility, as
illustrated in the following diagram -> |

Network Access and Control
As the industry consolidates production,
distribution, and transmission facilities, remote access and control of
monitoring equipment becomes increasingly important. The WFM700 Series
offers two forms of remote access and control:
- A 9-pin remote control port reports alarm conditions and lets you
control the monitor by selection one of seven available instrument presets
- A network remote control interface lets you view the WFM700 displays
using a standard Web-browser over an Ethernet-based network
- SNMP (Simple Network Management Protocol) speeds development and
integration of remote control software for external control and reporting of
major functions of the WFM700, including all error alarms
| The network communication software supports both manual assignment of IP
addresses and the use of a DHCP server. |
