Applications
Quality control in the production and post-production of HD/SD digital video content
Monitoring and compliance checking in the distribution and broadcast of HD/SD digital video
Video equipment qualification and troubleshooting in the installation and maintenance of HD/SD digital video facilities and systems
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, multi-format, 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:
The Diamond Display helps you quickly and easily analyze RGB gamut problems. At a glance, you can tell if any part of the signal trace lies outside the graticule, indicating a gamut error. The display's construction makes it easy to isolate the source of the problem. Errors appearing only in the upper diamond indicate a problem with the blue component, while errors appearing only in the lower diamond indicate a red component problem. An error that appears in both diamonds exposes a problem with the green component. The Diamond display gives you a unique, visual indication of signal components that are causing gamut errors so you can quickly make the adjustments needed to correct the problem.
WFM700 Diamond display
The Split Diamond display separates the two diamonds to help you easily detect component values below the black level. Both the Diamond display and the Split Diamond display offer user-adjustable thresholds for the white and black level of each component, and a single touch returns you to default settings quickly.
WFM700 Split Diamond display
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, YP
b
P
r
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.
WFM700 YRGB Waveform display in parade mode
In addition to these digital waveform displays, the WFM700 products can also display a familiar composite representation of an SDI digital signal.
WFM700 Composite Waveform display
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 YP
b
P
r
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 P
b
P
r
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.
Selecting the composite graticule will show the color vector with the traditional compass rose display.  You can manually configure the compass rose for the appropriate composite standard, either NTSC or PAL, or let the instrument automatically select the appropriate display based on the type of signal monitored.  Like the composite analog waveform representation, you can apply either 0% or 7.5% setup levels to waveforms.
In the component representation, you can configure the display to either show or remove the compass rose graticule.  You can also choose to display the I and Q color axes.
WFM700 Vector display with composite graticule (compass rose)
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 bars 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 P
b
, while bowing in the lower half of the display represents timing errors between Y and P
r
. 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 (WFM700 HD, WFM700A, and WFM700M) or SMPTE 259M format (WFM700A and WFM700M).  The following table shows the supported signal formats
