Preface

This manual describes installation and operation of the WVR6100, WVR7000, and WVR7100 Waveform Rasterizers. These instruments rasterize serial digital video and composite video signals (depending on installed options) for an XGA display, providing a new standard of display quality and ﬂexibility. Basic operations and concepts are presented in this manual. For more detailed information, see the online help on your waveform rasterizer.

NOTE. This manual supports and describes the WVR7100 and WVR6100 rasterizers that were shipped with

System-software version 2 and later. For earlier rasterizers that shipped with version 1 of the audio hardware, you can upgrade your instruments to the newer software v ersion. However, the new software version only supports the old audio hardware with the original functionality with which it was shipped. You must upgrade to the new audio hardware to obtain the new audio capabilities.

Yo u should use this manual with earlier rasterizers only if you have upgraded to version 2 o f the System software, and then either upgraded to a new audio hardware or have no audio option installed. Otherwise, use the earlier version of the manual that shipped with your rasterizer.

Key Features

The WVR6100, WVR7000, and WVR7100 use digital processing to ensure accurate, stable, and repeatable measurements, and to provide a powerful monitoring solution for broadcasting, production, and post-production environments. The W VR7000 and WVR710 The instruments can be ordered with various options that enable additional monitoring capabilities. (See page 2, Options.)

To Connect Power and Powering On/Off

The waveform rasterizer operates from a single-phase power source with the neutral conductor at or near earth ground. The line conductor is fused for over-current protection. A protective ground connection through the grounding conductor in the power cord is essential for safe operation.

AC Power Requirements

The waveform rasterizer operates from an AC line frequency of 50 or 60 Hz, over the range of 100-240 Volts, without the need for conﬁguration, except the power cord. (See page 1, International Power Plugs.) The typical power draw is 50 W. Refer to the S and environmental requirements.

Connect the supplied power cord to the rear-panel power connector. There is no power switch on the waveform rasterizer, so the instrument will turn on as soon as you apply power.

Installation

To Install i

The waveform rasterizer can operate almost anywhere in the distribution system due to its high impedance, bridging, and loop-through inputs. This section describes two types of connections and presents information on line termination. The following diagrams are for serial digital systems, but similar connections are common for the analog composite inputs on the waveform rasterizer.

1. Connect your serial sources through a

patch panel to a serial router.

2. Connect the output of the serial router to a SDI loop through input for comparison.

3. Connect the other SDI loop-through input to the patch panel to jumper the signal that you want to compare to signal connected in step 2.

Line Termination

The waveform rasterizer uses passive loop-through, serial and analog video inputs. Accordingly, the loop-through input must be terminated externally. The passive loop-through capability of the inputs provides the beneﬁt of a signal path that is uninterrupted by input selection, power interruption, and even most internal faults. In addition, the waveform rasterizer directly monitors the actual signal traveling to downstream equipment rather than providing a retransmitted signal or requiring a duplicate input signal.

The loop-through capability is especially useful with the EYE and PHY options because it allows inspection of the actual signal on the cable. However, the signal received by the waveform rasterizer is also dependent on the quality of the downstream cabling and termination. Terminations with poor high frequency characteristics, 50 Ω BNC barrels, patch panel bulkhead feed-throughs, and other poor cabling practices cause reﬂections, which can result in excessive eye closure, jitter above 100 kHz, data errors, and even loss of lock at the waveform rasterizer.

Connecting to Monitors and Projectors Issues

Some monitors or projectors may have trouble adapting to the XGA output from the waveform rasterizer. This is because there may no area.

How to Operate

Getting Acquainted

The waveform rasterizer uses a ﬂexible, tiled display. The waveform rasterizer can display four tiles at one time. Each tile can display a different measurement, effectively creating four independent instruments. To enable the tiles to function independently, most of the controls only affect one tile at a time.

To Control the Display

1. To switch to tiled mode, toggle the FULL

button until it is unlit and there are four displays shown.

2. To select a tile to control, push one of the numbered tile buttons.

Note that the button you select lights and that a light-blue outline surrounds the tile. Both the lit button and the light-blue outline indicate the active, selected tile. Tile 4 is shown selected here.

Connecting Signals. When connecting audio signals to the Analog Input connectors, you can use either balanced or

unbalanced signals. If you connect unbalanced signals to the inputs, you should connect the unbalanced output hot lead to the balanced input positive pin and the unbalanced cold lead to the balanced input negative pin.

When connecting the Analog Output connectors, you can connect them as balanced or unbalanced. However, if you connect the balanced outputs to an unbalanced input, you must ground the unused lead. You can ground either lead, but using the negative output and grounding the positive output will effectively invert the phase.

NOTE. Note that grounding the unused lead does not attenuate the output but it does halve the clipping level. Therefore,

you must attenuate the output by at least 6 dB to avoid clipping. The output signal level in unbalanced mode is double the signal level in balanced mode.

Units that have both analog and digital capability can have AES or embedded inputs converted to analog and then routed to the eight balanced outputs.

Cursors track the live trace, so they may not be correctly registered on a frozen trace.

Cursors can be used with the Eye Display (Option EYE or PHY only) to measure electrical characteristics of an SDI signal. (See page 56, How to Monitor the SDI Physical Layer.)

For cursor measurements, you can use any gain setting, including variable gain (the waveform and the cursors are equally affected). Higher gain settings help match the cursor to the waveform.

To Freeze the Display

Pushing the FREEZE button captures the current image for traces (waveform, gamut, and vector), picture, status, and audio measurements, if selected. Freeze is useful for comparing sources or for capturing transient events. Press FREEZE to capture a display you wish to keep or show to someone else. In this application, the Fr ozen Only display mode may be best. For comparing sources, the Frozen + Live display mode is useful. To use this feature, select one source, press FREEZE to capture an image, then select the second source and compare.

Not all displays react identically to freeze. WFM displays capture a trace. For text displays, such as Status, pressing FREEZE halts updates to the display. T his allows you to view the different status displays without numbers or status readouts changing. The waveform rasterizer continues to log error status in the background while the display is frozen.

FREEZE works in both tile and full-screen m odes, but frozen images do not change from tile to full or full to tile. That is, if you freeze a trace in tile mode, the frozen image will not be shown if you go to full-screen mode. The frozen image will still be available if you go back to tile mode. Likewise, if you freeze a Waveform image in a tile and then switch the tile to another measurement such as Vector, the frozen wavefo rm image will be hidden. If you then change the tile back to Waveform, the frozen image will reappear.

For waveform displays, the frozen image is shown in a different color to distinguish it from the live image.

Timing a studio involves adjusting the references going to different sources so that their output feeds have the same timing when they arrive a common point, such as a production switcher. For digital systems, the timing typically only needs to be close, because most switchers have some tolerance to timing errors. For analog composite systems, the timing may need to be matched within a small part of a subcarrier cycle to prevent hue shifts when switching between sources.

The waveform rasterizer supports multiple methods and techniques of timing a studio. All of these methods require an external reference to the waveform rasterizers. The methods and techniques follow.

To Use the Timing-Display Method

The Tektronix proprietary Timing Display (patent pending) provides a quicker, easier to use measure of the timing of an input relative to the external reference:

The rectangular display automatically scales to match the input signal. For progressive signals the display represents one ﬁeld, for interlace signals the display represents one frame, and for composite inputs the display represents one color frame.

The cross-hair in the center represents zero offset, and the circle represents the timing of the input signal. Lines of advance or delay are shown as vertical displacement, while timing errors of less than one line are shown as horizontal displacement. If the input is at the same time as the reference, then the circle will be centered on the cross-hair.

The timing offset is also shown numerically as lines and micro-seconds of advance or delay in the boxes at the right side of the display.

For input and reference signals with closely related frame rates, there is only one timing relationship, so a single circle is shown on the display to indicate the timing offset of the input signal.

WVR6100, WVR7000, and WVR7100 Waveform Rasterizers Quick Start User Manual 39

For input and reference combinations with more complex relationships, multiple circles are displayed to indicate all the possible inter readouts will correspond to the timing indicator circle with the emphasis.

Usage Notes

The resolution of the timing display for Composite and SD signals is one 27 MHz clock cycle or 37 ns. For HD signals, it is one clock at 74.25 MHz, which equates to about 13.5 ns. To get the greater accuracy needed for a composite signal, ﬁrst use the timing display to get close, then use a vector display for the ﬁnal burst phase alignment. Since the waveform rasterizer can display both the timing display and a vector display simultaneously (each in its own tile), this process can still be easy and quick.

For composite signals the deﬁnition of time aligned is obvious but for an SDI input relative to a analog reference the situation is more complex. For the timing display, the deﬁnition of zero offset on an SDI input uses the methodology described in SMPTE RP168. This method speci ﬁes the SDI signal will be converted to analog. The converted analog signal is then compared to the analog reference. For the conversion, a D/A converter w ith delay of about three microseconds is used.

In the relative to rear panel mode, this three microsecond c onversion delay is accounted for in the displayed offset. In the Relative to Saved Offset mode, it has no effect.

To Time Multiple Inputs to a Router

You can also use the Relative to: function to set the offset between a master signal and a reference signal as the zero-point reference for time-down applications. The Relative to: box indicates the chosen zero point for the timing display:

HowtoTimeaStud

To Time the Inputs to a Router

1. Perform steps 1 through 5 of the previous

procedure. (See page 40, To Us e t h e Timing Display to Time a Signal to a Reference.)

2. Route the signal you want as the master to the appropriate input, SDI or Composite, and terminate properly.

3. Route the reference signal to the reference input and terminate appropriately.

4. Save1thetimingoffsetforthemaster input ( MEAS > Save Offset > Press >

Select ) and select Relative to: Saved Offset mode from the pop-up menu.

5. Now select other inputs to the router to

be connected to the waveform rasterizer. For each input the relative timing will be displayed.

6. Adjust the timing offset at the master sync source to time down the inputs to the router to match the master.

You cannot save the timing offset if either the input or reference is missing or unlocked. You also cannot save a reference when in internal mode. Saving an offset in these conditions would lead to misleading results so it is not allowed by the instrument. A warning message will appear on the screen if you attempt to save the offset when it is not allowed.

Usage Notes

The resolution of the timing display is one 27 MHz clock cycle or 37 ns, for Composite and SD video. To get the greater accuracy needed for a composite signal, ﬁrst use the timing display to get close, and then use a vector display for the ﬁnal burst phase alignment. Since these two displays can be present simultaneously in separate tiles, this process is still easy and quick.

For composite signals, the deﬁnition of time aligned is straight forward, but for an SDI input relative to an analog reference, the s ituation is more complex. For the timing display, the deﬁnition of zero offset on an SDI input assumes the SDI signal will be converted to composite. The converted composite signal is then compared to the analog reference. For the conversion, a half-band ﬁlter with a 33 clock-cycle delay and an analog reconstruction ﬁlter are assumed. This conversion introduces a delay of about 3 µs.

In the Relative to: Rear Panel mode, this 3 µs conversion delay is removed from the measured offset before the display is generated. In the Relative to: Saved Offset mode, it has no effect.

This timing relationship between input and reference is also compatible with the waveform mode. That is, if you have zero timing on the Timing display and change from internal to external reference, the displayed waveform will not shift position.

When timing analog composite s ignals, adjust the system phase with the Vector display. The Vector display is described in Timing Displays for Simple Versus Complex Timing in the Supplemental Operating Information chapter of the WVR61000, WVR7000, and WVR7100 User Technical Reference.

NOTE. If you have an input and reference combination that requires m ultiple timing indicator circles, then it can be

misleading to c

ompare timing offsets between multiple inputs. Because the timing display chooses the smallest of the possible timing offsets, if a large timing difference exists between two inputs, then they may not be matched. This problem will also occur using traditional timing methods unless one uses something similar to the SMPTE318 10 ﬁeld ﬂag to identify a speciﬁc sub-m

For composite w aveforms, the legal limit is simply the maximum level allowed for the combination of luma and chroma. This limit depends on the application. For example, a video tape machine may be able to record and play out signa

The Diamond display effectively shows how the R, G, and B signals relate, making it a good tool for detecting gamut errors. The waveform rasterizer converts the Y, P

and P components recovered from the serial signal to R, G, and B to form the Diamond display. To predictably display all three components, they must lie between peak white, 700 mV, and black, 0 V.

For a signal to be in gamut, all signal vectors must lie within the G-B and G-R diamonds. Conversely, if a signal vector extends outside the diamond, it is out of gamut. The direction of an excursion out of gamut indicates which signal is e xcessive. Errors in green amplitude affect both diamonds equally, while blue amplitude errors affect only the top diamond and red errors affect only the bottom diamond.

Luma limit thresholds can be conﬁgured for identifying luma exceeding threshold limits. They apply to both the incoming SDI and to the arrowhead representation of the SDI input as a composite signal. By deﬁning these levels in percent, they automatically account for the presence or absence of setup.

The thresholds are affected by your choice of set-up or no set-up for the Arrowhead display.

1. Perform the To Set Up for Gamut Checks procedure. Select Arrowhead in step 5. (See page 47.)

2. Compare the signal to display to determine out of gamut luminance. Note the following:

The adjustable thresholds are indicated by the dark blue horizontal graticule lines.

The thresholds are deﬁned in terms of percent of full scale.

The range for the Upper limit is 90% to 108%.

The range to the Lower Limit is -6% to +5%.

Another useful Arrowhead function is a measure of how well the a ctive v ideo signal is using the dynamic range of the video channel. A properly adjusted signal should be centered in the arrowhead graticule and have transitions that approach all the limits.

How to Monitor

With Options EYE and PHY (WVR6100 and WVR7100), the waveform rasterizer supports monitoring and measurement of the SDI physical layer in the following ways:

Option EYE. If present, this option adds support for eye pattern monitoring of the physical layer of video signals. WVR6100 instruments display eye patterns for only SD signals. WVR7100 instruments display eye patterns for HD signals, and also for SD signals when Option SD is installed.

Option PHY. If present, this option includes the Option EYE features and adds automatic eye measurements and a jitter waveform display to aid the moni toring of the SDI physical layer. WVR6100 instruments display jitter waveforms for only SD signals. WVR7100 instruments display jitter waveforms for HD signals, and also for SD signals when Option SD is installed.

With Options Eye and PHY installed, you can use the following display modes to monitor the SDI physical layer:

Eye Display. On this display, you can use the voltage and time measurement cursors and their readouts to monitor amplitude and timing measurements on the Eye waveform. A jitter thermometer and readout displays the jitter magnitude. You can set the high-pass ﬁlter to allow measurement of different jitter types (timing and alignment). The jitter thermometer graphically relates the jitter measurement to the alarm limits. With Option PHY installed, you can use the Eye press-and-hold menu to access the Jitter waveform display.

You can c o nﬁgure the instrument to show multiple Eye displays, each of which is controlled by one of the two jitter engines in the waveform rasterizer. The Jitter1 engine controls Eye displays in the top two tiles. The Jitter2 engine controls Eye displays in the bottom two tiles. The two jitter engines allows you to set different ﬁlter bandwidths in the upper and lower tiles so that you can monitor both timing and alignment jitter at the same time.

the SDI Physical Layer

Jitter Display. On this display, you can view additional time-domain information that is useful in separating sources of jitter, whether they are w ithin a single circuit on a circuit board, or from various pieces of equipment in a system. The additional information includes the following:

Jitter components that are synchronous or nearly synchronous to video line or frame. These appear as stationary or near-stationary artifacts in line or ﬁeld sweeps.

The wave shape of the jitter as modiﬁed by the high-pass ﬁlter setting.

SDI Status Display. This display shows both the Jitter1 and Jitter2 thermometers described above. Additionally, a Cable Loss thermometer indicates the signal loss due to cable length. Use the CONFIG menu to con ﬁgure the instrument for the cable type and length of your installation. With Option PHY installed, the SDI Status Display also shows the eye amplitude, eye risetime, eye falltime, and eye rise-fall delta measurement values.

Similarly, the automatic risetime and falltime measurements use histograms to ﬁnd the centers of the distributions of 20% and 80% crossings. The difference between manual and automatic measurements is usually insigniﬁcant for clean, symmetrical signals.

To Take Jitter Measurements

After you c onﬁgure the instrument for Eye measurements, you can take jitter measurements using one of the following:

Measurement cursors on the Eye display

SDI Status display

Jitter display (Option PHY only)

NOTE. Many jitter problems in systems have resulted from genlocking clocks to other references, such as the horizontal

synchronization pulse. Reference jitter transferred by genlocks into a serial system is typically between 20 and several hundred Hertz. Also, the phase detection process used by the genlock can add noise, which results in jitter in the 10 Hz to 1 kHz range. Use the appropriate BW Limit ﬁlter selection to include or reject genlock jitter from a measurement.

Select the 10 Hz bandwidth ﬁlter to measure the total broadband jitter (use this setting if composite D/A conversion is planned).

The simplest way is to measure jitter is to use the jitter readout. The jitter measurement readout and thermometer are derived from the jitter waveform, even when displayed in an Eye display. Those same readouts are also shown in the SDI Status display.

The Eye and Jitter waveform displays provide more qualitative jitter information. The Eye display shows the presence and magnitude of the jitter, and its potential for causing data errors as the eye closes. The Jitter display provides added time-domain information such as the following:

Whether there are jitter components that are synchronous or nearly synchronous to the video line or frame (these components appear as stationary or near-stationary artifacts in line or ﬁeld sweeps).

The wave shape of the jitter.

By looking at jitter in both displays, you can separate the sources of jitter, whether they are within a single circuit on a circuit board, or from various pieces of equipment in a system.

The following example shows the display of a signal with a lot of jitter. (See Figure 1 on page 69.) In the top two tiles, the high-pass ﬁlter is set for 10 Hz, so all jitter above 10 Hz is displayed. In the lower two tiles, the high-pass ﬁlter is set for 100 Hz, removing most of the 30 Hz jitter and leaving the spikes. Both Jitter displays are set for two-ﬁeld sweep.

In the example, the upper Eye display shows a fairly even jitter spread, suggesting a moderately uniform statistical distribution of jitter. This jitter is from a sine wave component; there is no indication of jitter spikes. In the lower Eye display, the jitter is more of a low-density haze suggesting a less uniform jitter distribution (as indicated from the spikes).

After you have conﬁgured the instrument for Eye measurements, you can take cable-loss measurements using the SDI Status display.

NOTE. The Approx Cable (length) and Source Level readouts of the SDI Status display are derived from the m easured

Cable Loss and the speciﬁed Cable Type. The Source Level readout indicates the calculated signal amplitude at the signal source, even w hen the signal level is greatly reduced at the waveform rasterizer due to cable loss. Therefore, the automatic Eye Amplitude measurement (Option PHY only) may be signiﬁcantly less than the indicated Source Level. The accuracy of the Approx Cable (length) and Source Level readouts depend strongly on correctly setting the Cable Type, and on the quality of the cable and connections in the signal path.

How to Monitor Audio

The waveform rasterizer provides several methods to monitor audio signals. You can measure levels, monitor phase, display phase correlation, and monitor surround-sound audio. You can specify meter ballistics and scales, set the Test and Peak Program indicator levels, and specify how phase is displayed.

NOTE. The audio monitoring features described in this chapter require that appropriate audio options are installed. (See

page 2, Options.) For example, Option DS adds support for only Digital audio monitoring in embedded and AES/EBU inputs, while a Option AD equipped instrument can monitor both Analog and Digital audio in these inputs. Note that the options listed with a preﬁx W VR6UP -- (for the WVR6100 options), WVR70UP-- (for the WVR7000 options), or WVR7UP-- (for the WVR7100 options) support upgrades to previously purchased instruments.

For a list of the options that are installed on your product, press the CONFIG button. In the C ONFIG menu, select the Utilities submenu. The View Instruments Options entry lists the installed options for your instrument.
