This section contains information about installing and powering on the waveform monitor. Instructions for performing firmware upgrades are located in the

WFM700 Series Technical Reference document on the CD-ROM.

Hardware Installation

NOTE. Instructions for installing or removing the waveform monitor from a cabinet, and for adding or removing a module from the instrument are located in the WFM700 Series Technical Reference document on the CD-ROM.

The waveform monitor is shipped in a wrap-around chassis that covers the instrument bottom and two sides. A cover is installed on the chassis, and the rear panel is made up of the module rear panels.

You can operate the waveform monitor in the instrument chassis (be sure the cover is on) or installed in an approved portable cabinet or rack adapter. You can also install the waveform monitor in a custom installation, such as a console.

CAUTION. Do not install the waveform monitor in any cabinet except those that are listed in Optional Accessories on page 1--4. Attempting to do so can damage the waveform monitor and the cabinet.

If you install the waveform monitor in a custom application, such as a console, be sure to provide adequate airflow. Follow these guidelines:

H Do not block the ventilating holes.

H Adhere to the clearance requirements that are listed in the specification tables of the WFM700 Series Technical Reference document on the CD-ROM.

CAUTION. Failure to provide adequate airflow to the waveform monitor could cause the instrument to shut down (refer to Table 2--2 on page 2--3 for LED fault codes). If the airflow is blocked and the instrument does not shut down, the instrument could be seriously damaged.



Connecting Power

The waveform monitor 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.

WARNING. To avoid serious personal injury from electric shock, do not operate the instrument with the cover removed. When power is supplied via the power cord, line voltage will be present inside the waveform monitor, even if the unit is in standby mode.

AC Power Requirements

The waveform monitor 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. Refer to page 1--2 for the power cord options.

The typical power consumption is 100 W with one video module installed and

125 W with two video modules installed. Power consumption increases by a negligible amount when there is an Option DG audio module installed. Refer to the product specification tables in the WFM700 Series Technical Reference document on the CD-ROM for additional information on power and environmental requirements.

CAUTION. Use only power cords that are approved for the country of use. Using non-approved power cords could result in fire or shock hazard.

Powering On the

Instrument

Follow these steps to power on the waveform monitor:

1.

Plug the supplied power cord (IEC 320) into the back of the instrument.

Refer to page 1--2 for a list of power cord options.

2.

Plug the other end of the power cord into a standard wall outlet.

3.

Press the ON/STBY button to bring the waveform monitor out of standby mode.

Description / suggested action

No power. Press the ON/STBY switch for normal operation. Check that the instrument power cord is plugged into the local power supply.

Normal operation.

The LCD may be damaged if operated at low temperatures. If the internal temperature sensors detect a low temperature, this fault code will be asserted. Let the unit warm up and cycle the power or press the ON/STBY switch for normal operation to occur.

This is a transient state. It should never last more than one second. It occurs when the internal sensors detect that one of the internal supplies is out of the allowable range. In this state, the instrument will be reset.

This state can occur due to an intermittent problem that requires service or from a drop-out on the AC line. If the fault persists for more than one second, then the instrument will go to the Power Supply

Fault state.

It is normal for the momentary fault state to be asserted when the AC line is removed while the instrument is running.

If the internal monitors detect that one of the internal power supplies is out of its allowed range, the instrument will shut down and the Power

Fault LED code will be asserted. This can be triggered by multiple drop-outs on the AC power supply to the instrument.

If this fault code is present, press the ON/STBY switch to reset the instrument. If the fault code reoccurs, refer the instrument to qualified service personnel. If the waveform monitor seems to be operating properly, monitor the AC power supply to be sure there are no problems in the power source.

The internal temperature sensors will shut down the instrument at

75

_C to prevent damage to the components if the ambient temperature is too high or if the airflow is blocked.

If this occurs, the Overtemp fault code will be asserted. Let the instrument cool down and cycle the power or press the ON/STBY switch to resume normal operation.

This is asserted if the Environmental Controller is not able to test the temperature sensors and fan circuits. If this occurs, refer the instrument to qualified service personnel.

Power

Video inputs

Audio inputs / outputs

(Option DG only)

Description

This instrument is intended to operate from a single-phase power source with one current-carrying conductor at or near earth ground (the neutral conductor). Only the Line conductor is fused for over-current protection. The fuse is internal, on the Power circuit board. Systems that have both current-carrying conductors live with respect to ground (such as phase-to-phase in multiphase systems) are not recommended as power sources. Mains frequency is 50 or 60 Hz. Operating voltage range is continuous from 100 to 240 VAC, ±10%.

The waveform monitor provides the following video input connectors:

NOTE: Input A and Input B are separate signal inputs and cannot be used as a loop-through signal path.

INPUT A and INPUT B. Digital, 75 Ω terminating input for signal to be monitored. For WFM700HD, this can only accept 1.485 Gb/s High Definition serial video. For the WFM700A and WFM700M, this input can accept HD and 270 Mb/s Standard Definition video.

REF IN LOOP-THROUGH. Compensated for 75

Ω impedance; requires proper termination at one end of the loop-through connector or at the receiver in a monitored system. Provides for connection of an external synchronization signal such as black burst or composite video.

AUX IN. Future capability.

When your instrument has the optional WFM7DG audio module installed, the waveform monitor provides

BNC connectors that function either as inputs for external AES/EBU audio (not necessarily associated with any video) or as outputs of the de-embedded AES audio associated with the selected video input.

Use the Audio Inputs/Outputs submenu of the Configure menu to configure these connectors.


Functional Overview

Table 2- 5: Rear-panel connectors (Cont.)

Connector(s)

Multi-pin connectors

Coaxial Outputs

Description

The waveform monitor provides the following multi-pin connectors:

VGA PIX MON. A copy of the PIX G/Y, B/Pb, R/Pr pix mon outputs. This allows using an inexpensive

VGA monitor for non-critical HD applications. Most computer monitors will not lock to 50 Hz vertical rates or to Standard Definition line rates, so this may not work in all applications.

EXT VGA. Provides an exact copy of the instrument display to drive an external monitor.

REMOTE. 9-pin subminiature D-type connector used as a Ground Closure interface for remote control.

ETHERNET. (10/100 Base T). 10/100 Mbit/sec Ethernet interface. Used for for web-based remote control of the instrument and for downloading firmware upgrades.

The waveform monitor provides the following coaxial outputs:

PIX G/Y, B/Pb, R/Pr. Provides three 75

Ω component signal outputs to drive a component picture monitor. You can set the output format to YPbPr or RGB. Out of gamut input signals cause the affected areas to be highlighted on the monitor display. This gamut error highlight or “bright-up” signal is controlled in the Configure menu.

SD PIX MON. This output is a copy of the PIX G/Y, B/Pb, R/Pr pix mon output, but is reclocked in SD serial digital format. It is operational only for SD format input signals, and only while the SD signal is being displayed on the screen of the waveform monitor. In addition, there is no signal output from this connector on a module while an input signal from a second module is being displayed on the screen.

SERIAL OUT. Provides a version of the selected signal input (Video Input A or B). There is no signal output from this connector on a module while an input signal from a second module is being displayed on the screen.

JITTER OUT. (WFM700M only) Provides a 75

Ω output signal from the jitter demodulator. This signal is only valid when the instrument is in Jitter mode. Any signal present on this output at other times is not a calibrated jitter signal. The jitter filter selection does not affect this signal.

This signal is used as an input to an oscilloscope or spectrum analyzer to do additional analysis on the jitter. You can view the same jitter waveform on the waveform monitor using the Jitter display mode.

AUX OUT 1 / AUX OUT 2. Future capability.

Freeze Menu

Press the FREEZE button to open the Freeze menu shown in Figure 2--12.

Freeze Mode lets you:

H Capture (freeze) the active signal and hold it in the Capture buffer.

H Display the frozen signal or the live signal.

H Compare the frozen signal and the live signal by selecting Display Both.

NOTE. The Freeze function for the Data display in Measure mode freezes only the data waveform (left side of screen). The data list (right side of screen) continues to update in response to the incoming serial stream.

The Freeze function does not operate for the Audio display because Audio display elements cannot be frozen. If a waveform is frozen, it will not be overlaid with audio when the Display Both function is selected.

If you have frozen a waveform (even if it is not displayed), the pixel density of the live waveform will be reduced. This is because the frozen waveform is using a portion of the display memory. Delete the captured waveform to regain full waveform density and display performance.

Alarms

Use the Configure Alarms submenu of the Configure menu to select which error conditions you will monitor and how you will be notified in the event of an error.

The alarms are organized into the following groups to help you locate a desired alarm: General, Serial, Audio (Option DG only), Auxiliary, and Physical

(WFM700M only).

The top level of the submenu display shows which notification methods are enabled. An “X” indicates that a notification method is selected and an “O” indicates that the notification method is not selected.

Refer to the WFM700 Series Technical Reference document on the CD-ROM for a description of each alarm condition.

Possible Alarm Actions

For each available alarm, you can select one or more notification methods:

NOTE. If you do not select a notification method for an error, you will not be notified if that error occurs.

H On-screen. An icon appears at the top of the current display. This notification method is disabled when the Configure menu is open.

H Beep. The instrument makes an audible alarm.

H SNMP. The instrument sends an SNMP trap out the Ethernet port for a remote notification that an alarm condition occurred. You must enable and configure the instrument for SNMP control using the Communications submenu of the Configure menu before SNMP traps can be sent.

Refer to the WFM700 Series Technical Reference document and the

WFM700 Series SNMP MIB Reference on the CD-ROM for more information about using SNMP alarm notifications.

H Logging. The instrument makes an entry in the Event Log. Refer to Logging on page 3--32 for more information.

H Ground Closure. The instrument sends a signal out the Remote port for a remote notification that an alarm condition occurred. You must enable the

Ancillary Data Display

The Ancillary Data display (see Figure 3--1) shows the raw (undecoded) data words in the selected ancillary data packets. The ancillary data is shown only in hexadecimal format. Since the display is updated at approximately 2-second intervals, rapid data changes cannot be detected.

Use the DID and SDID/DBN soft keys in conjunction with the general purpose knob to select the DID and/or SDID values for the type of ancillary data packet to be monitored. DID and SDID values have the following characteristics:

H DID and SDID values range between 0x01 and 0xff.

H For DID values in the range 0x00 -- 0x7F (Type 2 packets), the SDID values are used.

H For DID values in the range 0x80 -- 0xFF (Type 1 packets), there are no

SDID values used (the SDID soft key is greyed out).

Table 3--1 lists the DID and SDID values that are defined for common types of ancillary data.

Audio Mode

For instruments with only video modules installed, Audio mode provides a protocol-level check for the AES stream. The Embedded Audio Status screen reports the following information:

H Which video input is the source of the embedded audio

H The standard used by the audio signal

H Whether the header indicates that audio is present on each pair of channels

(Status = Present or Not Present)

Audio Mode (Option DG Only)

NOTE. The information below describes the Audio mode display for instruments with the Option DG audio module installed.

Configuring the

Instrument for Audio

Measurements

Use the following submenus of the Configure menu to set the various instrument parameters for audio measurements: Audio Inputs/Outputs, Audio Displays, and

Selecting the Channel Pair for the Lissajous Display

To select which channel pair is displayed on the Lissajous display:

NOTE. The channel pair labels depend on the Audio Program Type setting

(surround or stereo pairs).

1.

Touch the Lissajous Pair: soft key to open the Audio Lissajous Pair menu.

2.

Select a channel pair by performing one of the following actions:

H Touch the soft key for one of the four default channel pairs.

H Touch the Custom Pair: soft key to select the custom channel pair you specified using the Configure Custom Pair soft key.

H Touch the Configure Custom Pair soft key to open the Custom Lissajous

Pair menu where you can specify which audio channel is displayed in each Lissajous channel.

3.

Touch the Done soft key to save your selection.

NOTE. For SD embedded audio only:

Preservation of audio-sample phase between different AES channel pairs or across embedded audio groups is not supported by SMPTE 272M alone. The

Lissajous Custom Pair display may not correctly represent audio phase unless the following extensions to SMPTE 272M are observed:

1. The selected audio channels must be embedded with exactly the same audio sample frequency.

2. The intended sample alignment must be represented by the average embedded sample position.

3. Most lines should carry phase-aligned samples and should have an equal number of samples from each group. This minimizes the number of attempts needed to reestablish correct alignment.

These are not requirements of SMPTE 272M and some embedders do not meet these criteria. Furthermore, some de-embedding equipment may not make use of these characteristics, even if present. In these cases, there may be variation in the displayed audio phase between different AES channels. The variation is typically

ᐔ 1 audio sample, but may be greater depending on random startup conditions and the design of the embedder/de-embedder.

Audio Input Mapping

Restrictions for Surround

Sound Display

The Surround Sound display is restricted to using signals from only certain audio input channels. The factory default settings for mapping the audio inputs are the correct settings for using the Surround Sound display.

For embedded audio groups 1 and 2, the display only works when channels 1 and 2 are mapped to the L--R bars, channels 3 and 4 are mapped to the C--Lfe bars (the Lfe channel is ignored), and channels 5 and 6 are mapped to the Ls--Rs bars. Channels 7 and 8 are always ignored. Similar rules apply for embedded audio groups 3 and 4 and for the external AES audio inputs. You cannot remap the audio inputs when you are using the Surround Sound display.

Interpreting the Surround

Sound Display

The Surround Sound display indicates the audio level balance among the left (L), right (R), left-surround (Ls), and right-surround (Rs) channels as cyan lines on the ruled scales radiating from the center. The scale has tic marks at 10 dB intervals. An additional tic mark indicates the --18 dB level. The --18 dB and

--20 dB levels are typically used for aligning audio levels .

The cyan 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 are uncorrelated.

The Center Volume indicator displays the sound volume of the center channel as a vertical yellow bar between the L and R channels, and connects the ends of the

L, C, and R audio level indicators with straight lines.

Phantom Sound Indicators (PSI), located on each side of the Surround Sound display, indicate the location of potential phantom sound sources formed by adjacent channels. The white tic marks on these moving bar indicators show the phantom source locations. The bar length indicates the correlation between the adjacent channels. A short-to-medium length green bar indicates positive correlation between the channels, forming a localized phantom sound source located at the white tic mark. The bar grows to full length and changes color to yellow as the correlation moves to zero, indicating a wide, non-localized sound image. The bar changes color to red for adjacent channels with significant negative correlation. For negative correlations, the ends of the PSI for the L and

R channels will continue to grow at a 45

_ angle while the other PSIs remain at full length.

A fifth PSI at the top of the display shows potential phantom sources formed by the LC channel pair and the CR channel pair. If the L, R, and C channels all have the same signal level, the white tic mark on the bar will appear directly above the

C level indicator. The white tic mark will move right or left depending on the relative balance between the three channels. A short bar to the left of the white tic mark indicates a positive correlation between L and C. The bar will grow as the correlation decreases. Like the L--R PSI, the bar will continue to grow at a

45

_ angle for negative signal correlations. The bar to the right of the white tic mark behaves in the same way, depending on the C--R correlation. This PSI indicator uses the same color coding as the other PSI indicators.

Reference

Channel Status Display

The Channel Status display shows the channel status information, for one channel pair at a time, that is embedded in the AES3--1992 (professional) or

IEC--60958-3 (consumer) digital audio channels. You can select from the following four display formats: Text, Binary, XMSN Order Binary, or Hex.


Display

This display reports the following information:

H Which video input is the source of the embedded audio

H The standard used by the embedded audio signal

H Which audio groups are selected (use the Embedded Input Map to change)

H The embedded group sample phase (HD signals only)

NOTE. For HD signals, the Embedded Group Sample Phase readout indicates the misalignment, in microseconds and samples, between the audio samples of the two selected embedded audio groups. The readout turns red when the misalignment exceeds about 0.625 audio samples. The readout displays N/A if one or both of the selected audio groups is missing, or if the video signal is SD.

H Whether the header indicates that audio is present on each pair of channels

(Status = Present or Not Present).


Reference

Bowtie Mode

The Bowtie display evaluates the relative amplitude and timing between the three video channels. To access the Bowtie mode, press the MEASURE button, touch the Measure Menu soft key, and then touch the Bowtie soft key.

The Bowtie display requires a special test signal to be sent from the monitored source. The Tektronix TG2000 Signal Generation Platform can produce a Bowtie test signal with 20 ns time marks, which aid in signal evaluation. The signal is a

500 kHz sinewave on CH 1 (luminance) and 502 kHz sine waves on CH 2 (Pb) and CH 3 (Pr).

Measurements

The Bowtie display is made up of two separate waveforms. The left waveform always compares CH 1 to CH 2. The right waveform always compares CH 1 to

CH 3.

Timing Measurement. The timing measurement is based on the alignment of the center marker and the null point at the center of the waveform. The generator provides a center marker, which is centered on the null point when interchannel timing is correct. In Figure 3--6, the chrominance channel, CH 3 (Pr), is advanced relative to the luminance channel by 20 ns.

Relative Gain Check. The relative gain check is based on the null point at the center of the Bowtie waveforms. If the gains are not equal, the center null point will not be a complete null. If the gain error is in CH 1, neither waveform has a complete null. If CH 2 gain is off, the left waveform will not null completely, but the right one will. If the gain is off for CH 3, as in Figure 3--6, the left waveform will be normal and the right one will not reach a complete null.

The instrument provides a composite representation of both SD and HD component signals. To access the composite display, set the color space to composite in Waveform mode or select Composite Graticule in Vector mode.

Data Display (WFM700M Only)

The Data Display mode shows the actual SD or HD input data without any interpolation.

Data Display Colors and Units

Different fields of the data stream are shown in different colors, as shown in

Table 3--2. Use the Readout Format soft key to view the data in Hex, Decimal, or

Binary units.

Video / Data Selection

The instrument provides two modes for representing signal data: Video and Data.

Video Mode. Shows the data like the video YPbPr display in waveform mode, but without interpolation. The Y, Cb, and Cr traces are offset vertically to separate them, but are aligned temporally. Since Cb and Cr have half the data rate of Y, the samples appear twice as long. Use the Select Channels soft key to turn off individual components of the display.

Data Mode (SD). Shows the data in the same sequence as it occurs in the serial domain. You see a sample of Y, then of Cb, then of Y’ (Y prime), and then of Cr.

Then the sequence repeats. The Y sample is the co-sited sample, and the Y’ sample is the isolated luma sample.

Data Mode (HD). Splits the serial data into a Y channel and a multiplexed Cb/Cr channel. The intent is to show the data in the same orientation as it occurs in the serial domain, even though it is displayed as 8 or 10 bit values.

Diagnostics

The waveform monitor provides diagnostics capabilities, which are accessed through the System submenu of the Configure menu. You can view or print the

Diagnostics Log, which contains the results of the last diagnostic test that the instrument performed. You can also download the Diagnostic Log using the

Remote Web Interface.

Powerup Diagnostics

Setting

At power up, the instrument runs either full or brief diagnostics, depending on the setting in the System submenu of the Configure menu.

Running Diagnostics

You should run diagnostics after installing a new module, upgrading the instrument firmware, or when troubleshooting suspected instrument problems.

Warning messages are displayed in yellow text; PASS and FAIL messages are labeled PASS (green text) or FAIL (red text). You have the following diagnostic choices:

Run Full Powerup Diagnostics. The instrument goes through all of the diagnostics and displays the results.

Run Internal Digital Path Diagnostics. The instrument checks the main digital paths within the instrument and displays the results of the various tests. If there is only one video module installed, expect some yellow warnings. After running this diagnostic, you must reboot the instrument to return to normal operation.

Run Audio Path Diagnostics (WFM7DG Only). The instrument checks the audio paths within the instrument from the optional WFM7DG audio module and displays the results of the various tests. After running this diagnostic, you must reboot the instrument to return to normal operation.

Eye / Jitter Mode (WFM700M Only)

Press the EYE button to access the Eye / Jitter menu and measurements.

Making Eye

Measurements

The Eye pattern display presents a voltage-versus-time waveform composed of multiple sweeps of the SD or HD serial bit stream.

You can set the sampled eye pattern to display either a full word of correlated data (10 Eye display in SD; 20 Eye display in HD) or a three-data-bit overlay showing jitter uncorrelated to the parallel word (3 Eye display). In the word-correlated mode, the sweep is also synchronized to the video, so that you can see any shift in the data stream timing correlated to horizontal or vertical video information. This mode is most useful for detecting jitter patterns or modulation related to parallel-to-serial conversions.

Jitter is seen in the eye diagram as a horizontal thickening of the trace. As jitter increases, the opening in the eye shrinks until the receiver can no longer reliably decode the serial stream.

The usefulness of the eye measurement decreases with long cable lengths. Even a short cable will slow the rise time and make evaluation of a source difficult.

Slightly longer cables will make one eye run into the next. This is called intersymbol interference. It makes the eye appear to have multiple levels and closes the eye opening vertically long before the receiver fails to decode the signal. The only information the eye measurement gives on longer cables is some idea of the cable length.

Different clock recovery bandwidths can be selected to help isolate the frequency of any jitter that is observed. When a bandwidth setting is chosen, only jitter at frequencies above that bandwidth are observed.

You can turn on or off a readout that displays automatic measurements and a histogram of the eye waveform. Refer to Automatic Eye Measurements on page 3--18 for more information.

Setup for Eye Measurements. Perform the following steps to prepare the instrument for Eye measurements:

1.

Connect a 100% Color Bar, serial video-signal to the instrument using a

75

Ω cable of two meters or less in length. Use high quality, low loss coaxial cable, such as Belden 8281.

2.

Press the GAIN button and select 1x vertical gain.

3.

Press the EYE button to select the Eye Pattern display.


Reference

Automatic Eye Measurements. When the Eye display is selected, you can use the

Eye Meas. soft key to turn on or off a readout that displays automatic measurements of the eye waveform (see Figure 3--7). The measurement readouts are colored red when the eye waveform exceeds the defined thresholds.

Use the Set Default Thresholds soft key to set the eye measurement thresholds to the levels defined by the associated standard (SD signals: SMPTE 259M;

HD signals: SMPTE 292M). Use the Set Meas Thresholds soft key to set custom threshold levels.

NOTE. The automatic eye measurements are based on the eye waveform display.

To ensure the best eye measurement conditions, the instrument sets the clock recovery bandwidth set to 1kHz. While the automatic eye measurements are running, the instrument prevents you from adjusting the recovery bandwidth setting or from adjusting the following signal controls: vertical and horizontal position, sweep and gain settings, and Line Select mode.

Reporting Automatic Eye Measurement Errors. When enabled in the Physical

Alarms submenu of the Configure menu, the eye measurement alarms will be reported to the Event Log in only the following two conditions:

H When the Eye display is selected and the eye measurement readout is turned on

H When the Event Log or Alarm Status displays are selected after the eye measurement readout is turned on

That is, if you enter the Eye display and turn on the eye measurements, and then you use the STATUS button to view the Event Log or Alarm Status displays, the eye measurement alarms will be active. If you select another display mode such as Jitter or Waveform, the eye measurement alarms will be disabled.

Measurement Accuracy Using the Measurement Cursors. If you use the measurement cursors to measure the eye waveform, you may measure a different result than that shown in the automatic eye measurements readout. This is because the internal peak detector can measure waveform excursions better than people can when using their eye to position the cursors.

Manually Measuring Amplitude. The following procedure shows you how to manually measure the signal amplitude using both the graticule and the Voltage

Cursors.

1.

Perform the initial settings for Eye measurements described in Setup for Eye

Measurements above.

2.

Use the CLOCK BW soft key to select the 1 kHz filter. This setting reduces the effects of timing jitter, which can obscure the amplitude measurement.

3.

To measure amplitude, use the graticule (1x gain) or use the voltage cursors.

Ignore any overshoot or undershoot on the rising or falling edges.

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

Signal sources should measure 800 mV p-p

ᐔ10%. Signal amplitudes outside of this range can degrade receiver performance.

Manually Measuring Aberrations. Serial sources should produce good signal transitions with a minimum of overshoot and ringing. To manually measure aberrations, perform the following steps:

1.

Perform the steps in Setup for Eye Measurements on page 3--17.

2.

Position one voltage cursor at the peak of the overshoot at the top horizontal part of the waveform.

3.

Position the second voltage cursor at the bottom of the top line of the waveform. Include any ringing (the oscillation following overshoot) in the measurement. Essentially, you are measuring the thickness of the top line of the waveform.

4.

The Voltage Cursor readout provides the signal amplitude.

5.

Perform the same voltage-cursor measurement on the bottom line thickness, including any undershoot and ringing.

NOTE. Aberrations at the top or bottom line of the waveform should not exceed

10% of the signal amplitude since automatic equalizer circuits in receivers may be sensitive to larger aberrations.


Reference

Manually Measuring Rise Time. Rise time measurements of the eye waveform check the performance of sources and signal degradation by cabling. The following procedure provides two methods for manually measuring rise time.

The first method uses variable gain to normalize the signal and the second method uses the percentage voltage cursors.

1.


2.

Method 1 -- Use variable gain to measure rise time.

a.

Use Variable Gain to resize the waveform to 10 major divisions. Position the top and bottom of the waveform on graticule lines.

b.

Position the first timing cursor at the crossing of the rising edge of the

Eye waveform and the graticule line two divisions above the bottom of the waveform as shown in Figure 3--8.

NOTE. You can use the horizontal MAG control in the Sweep menu for greater accuracy when adjusting the time cursors.

c.

Position the second time cursor at the crossing of the rising edge of the

Eye waveform and the graticule line two divisions below the top of the waveform as shown in Figure 3--8.

d.

The Delta time readout indicates the 20 -- 80% rise time measurement.

Figure 3- 8: Timing Cursors alignment for measuring 20- 80% rise time



Reference

3.

Method 2 -- Use the percentage voltage cursors to measure rise time: a.

Turn on the voltage cursors and set the voltage cursor units to %.

b.

Position the first voltage cursor to the top of the signal, and then position the second voltage cursor to the bottom of the signal.

c.

Touch the Set 100% soft key.

d.

Position the first voltage cursor to where the readout lists 80%, and then position the second voltage cursor to where the readout lists 20%.

e.

Position the first timing cursor at the crossing of the rising edge of the

Eye waveform and the 20% voltage cursor.

NOTE. You can use the horizontal MAG control in the Sweep menu for greater accuracy when adjusting the time cursors.

f.

Position the second timing cursor at the crossing of the rising edge of the

Eye waveform and the 80% voltage cursor.

g.

The Delta time readout indicates the 20 -- 80% rise time measurement.

Making Jitter

Measurements

The Jitter display mode plots jitter versus time as a trace and measures peak-topeak time jitter on the active input signal. The Jitter mode converts any phase modulation to amplitude and plots it against time.

Timing jitter is the deviation of signal transitions compared to those of a reference clock. Jitter results in Eye closure along the time axis, narrowing the window in which the data values can be accurately determined.

Jitter is characterized by both its magnitude and frequency. Signal transitions deviate from their ideal position by a peak amount and at one or more frequencies, depending on the sources. Typically, only high frequency jitter affects data recovery. But low frequency jitter can affect time-critical operations such as signal multiplexing and D/A conversion.

Jitter Demodulation. The Jitter measurement uses a demodulator method to determine signal jitter. The serial clock is recovered from the input signal and demodulated against a very stable oscillator, which translates any phase modulation (jitter) into a DC value. This DC value represents the phase difference between the input signal and the reference oscillator.

The resulting DC values plotted against time are proportional to jitter in the serial signal. This jitter waveform is passed through a high-pass filter and applied to a peak detector. The peak detector measurement is presented in the jitter measurement box. The demodulator can detect jitter up to 5 MHz.

Observing Word Correlated Behavior. The Eye Pattern display allows you to analyze word correlated jitter in video signals. Use the 10-Eye mode to analyze

SD format signals and use the 20-Eye mode to analyze HD format signals.

When video is serialized, a 270 MHz serial clock is derived from the 27 MHz rate parallel word clock. Often there is slight phase modulation of the serial clock between the transitions of the parallel clock producing jitter at data-bit transitions. This jitter is not random; it is correlated to the parallel word rate.

Also, the video pattern applied to the serializer changes at a 27 MHz rate or at an integer fraction of this rate. Any video pattern related effects in the serial system typically appear at fixed data-bit locations with respect to the parallel word.

In the 10-Eye or 20-Eye display modes, the trigger is on the parallel word boundaries, with 10 or 20 Eyes shown per sweep. Parallel word and TV-line correlated behavior can be seen in these modes. If a serial system has a disturbance that appears related to video patterns, either word or TV-line, use the

10-Eye (SD) or 20-Eye (HD) display mode to analyze the problem. Use the Line

Select function to place the area of interest in the Eye pattern display.


Reference

Using Line Select. When Line Select is off, the jitter measurement reflects the maximum amount of jitter in the full field. When Line Select is on and Line sweep is selected, the jitter measurement displays “line n jitter,” with n being the selected line number. The jitter measured on an individual line will always be equal to or less than the full field jitter measurement.

Bandwidth Filters. The waveform monitor provides four bandwidth filters: 10 Hz,

1 kHz, 10 kHz, and 100 kHz. These filters only show jitter terms above the selected filter frequency.

When you select a filter, depending on the active input signal, you select the jitter measurement type (Timing, Alignment, or neither, as defined by the

SMPTE standard). Use the lowest settings to measure timing jitter and the higher settings to measure alignment jitter. The type of jitter measurement is displayed in the Measured Jitter box.

To measure timing jitter, select the 10 Hz filter for both SD and HD video signals. To measure alignment jitter, select the 1 kHz filter for SD video signals and the 100 kHz filter for HD video signals.

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.


Reference

Reporting Jitter Measurement Errors. When enabled in the Physical Alarms submenu of the Configure menu, the Jitter alarm will be reported to the Event

Log in only the following two conditions:

H When the Jitter display is selected

H When the Event Log or Alarm Status displays are selected after the Jitter display is selected

That is, if you enter the Jitter display and then use the STATUS button to view the Event Log or Alarm Status displays, the jitter measurement alarm will be active. If you select another display mode such as Eye or Waveform, the jitter measurement alarm will be disabled.

Use the Set Default Thresholds soft key to set the thresholds back to the default values for the type of signal you are monitoring: SD (SMPTE 259M) or

HD (SMPTE 292M). The default value for the jitter measurement 0.2 UI, which is the maximum alignment jitter specification for both SD and HD signals and is the maximum timing jitter specification for SD signals (see Table 3--3).

Since the maximum timing jitter specification for HD signals is 1.0 UI, you must set the high-pass filter to 10 Hz and manually set the jitter threshold to 1.0 UI before the instrument will properly generate an alarm if the HD signal exceeds the SMPTE 292M timing jitter specification.

Use the Set Meas. Thresholds soft key to set a custom threshold level.

Measurement Accuracy Using the Measurement Cursors. If you use the measurement cursors to measure jitter, you may measure a different result than that shown in the jitter measurement box for the following reasons:

H The internal peak detector does a better job of measuring jitter excursions than a human can when using their naked eye to position the cursors

H The noise floor is removed from the jitter measurement readout but not from the cursor delta readout

Manually Measuring Timing Jitter. Perform the following steps to manually measure the timing jitter:

1.


2.

Select the 3 EYE mode, which shows peak jitter at each eye crossing.

3.

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

4.

Position the timing cursors to measure the width of the Eye zero-crossing point (see Figure 3--9). If necessary, use the Gain and Sweep menus for better vertical and horizontal resolution.

5.

Check that delta between the two timing cursors is less than the following over one horizontal line:

H SD signals: 740 ps (0.2 unit intervals per SMPTE259M)

H HD signals: 673 ps (1.0 unit interval per SMPTE292M)

Gamut Measurements

NOTE. Gamut error detection is disabled in Eye and Jitter display modes.

The waveform monitor features three types of gamut displays:

H The Diamond display shows the relationship between the R, G, and B video signals. The waveform monitor converts the Y, P b, and P r components of the signal into R, G, and B to form the Diamond display.

H The Split Diamond display separates the upper and lower diamonds to show excursions below black; otherwise it is identical to the Diamond display.

H The Arrowhead display checks that signals conform to legal composite gamut space.

NOTE. Refer to the reference document A Guide to Standard and High-Definition

Digital Video Measurements at the Tektronix, Inc. Web site (www.tektronix.com) for information about how the Diamond and Arrowhead displays are created and for information about defining legal and valid gamut signals.

Checking RGB Gamut

Use the Diamond or Split Diamond displays to check RGB gamut. For a signal to be in gamut, all signal vectors must lie within the G-B and G-R diamonds.

The direction of an excursion out of gamut indicates which signal is excessive.

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.

Use the Split Diamond display to see excursions below black in either of the

G--B or G--R spaces.

The intensity of a vector indicates its duration. A momentary out-of-gamut condition appears as a faint trace. Long duration violations show as a bright trace. Figure 3--10 shows out-of-gamut signals on the Diamond display.

Monochrome signals appear as vertical lines. Nonlinear component processing, such as from a gamma corrector that alters white balance, can cause deviations along the vertical axis.

Bending of the transitions indicates timing delays. When a color bar signal is applied, the vertical axis becomes an indicator of delay errors. The Diamond and

Split Diamond displays allow you to visualize interchannel timing errors. Use the Lightning display in Vector mode to quantify the amount of timing error.

The Diamond and Split Diamond graticules have marks to indicate conformance using 75% color bars. The edge of the diamond is used for 100% color bars.

Checking Composite

Gamut

The Arrowhead display shows out of gamut conditions in composite color-space, without requiring a composite decoder. The display plots luminance on the vertical axis, with blanking at the lower left corner of the arrow. The magnitude of the chroma subcarrier at every luminance level is plotted on the horizontal axis, with zero subcarrier at the left edge of the arrow. The upper sloping line forms a graticule indicating 100% color bar total luma + subcarrier amplitudes.

The lower sloping graticule indicates a luma--subcarrier extending towards sync tip (maximum transmitter power).

Arrowhead Graticules. The electronic graticule provides a reliable reference to measure what luminance plus color subcarrier will be when the signal is later encoded into NTSC or PAL.

On the NTSC Arrowhead graticule (see Figure 3--11), the 120 IRE line represents the level at which a transmitter starts clipping the signal. The --40 IRE line represents the sync tip level, while the 7.5 IRE line represents the setup level.

On the PAL Arrowhead graticule (see Figure 3--12), the 950 mV line represents the level at which a transmitter starts clipping the signal. The 930 mV line represents the upper limit of chrominance excursion, and the --230 mV line is the lower limit of chrominance excursion. The --300 mV line represents the sync tip level.

Signals exceeding the luminance amplitude gamut extend above the top horizontal limit (top electronic graticule line). Signals exceeding the luminance plus or minus peak chrominance amplitude gamut extend beyond the upper and lower diagonal limits. The bottom horizontal line shows the minimum allowed luminance level.

Setting Gamut Alarm

Limits

Listed below are general guidelines for setting gamut alarm limits for the

Diamond and Arrowhead displays.

Default Thresholds. Use the Grat / Gamut Default Setup submenu of the

Configure menu to select the standard used for default gamut thresholds: Tek or

IBU-R103. The Tek thresholds are the default gamut thresholds historically used by video monitoring equipment made by Tektronix, Inc. and are not intended to conform to an officially accepted video standard.

NOTE. When you select the Tektronix default limits, the RGB, Luma, and Y+C gamut thresholds are reset to the default values defined by Tektronix. When you select the EBU-R103 default limits, only the RGB and Luma gamut thresholds are reset since the Y+C gamut limits are not defined by the EBU-R103 standard.

When you touch the Default soft key in any of the Gamut Limit menus, all of the gamut limit thresholds are reset to the standard indicated on the soft key.

3- 30

Diamond Display Gamut Limits. Use the Gamut menu to set the upper and lower

RGB thresholds for a 5 mV tolerance ( +705 mV and --5 mV). This will cover the tolerance of any signal generator that provides color bars. This tolerance is close enough to the nominal values of 700 mV and 0 mV to be undetectable by the human eye.

Set the Horizontal/Horiz+Vert soft key setting to Horiz+Vert. This setting will trigger on gamut errors that form a block covering several video lines, and thus are more visible to the human eye.

Arrowhead Display Gamut Limits. Use the Limit Format soft key to set the instrument for NTSC or PAL gamut measurements. For North American applications of NTSC video signals, set the Setup control to 7.5%. In addition, set the upper Y+C Composite threshold to 120 IRE because that is the level at which a TV transmitter starts to clip the signal. Set the lower Y+C Composite threshold to --24 IRE because that is the lower limit of chrominance excursions.

For the majority of PAL video signal applications, set the Setup control to 0%.

Set the upper Y+C Composite threshold to 935 mV and the lower Y+C

Composite threshold to --235 mV because those are the limits of chrominance excursion.

For both NTSC and PAL signals, set the Horizontal/Horiz+Vert soft key setting to Horiz+Vert. This setting will trigger on gamut errors that form a block covering several video lines, and thus are more visible to the human eye.

Set the upper and lower luminance thresholds for a 3% tolerance (103% and

--3%) to monitor excessive luminance excursions.


Reference

Filtering. Two filters allow you to accept overshoot that would otherwise be reported as a gamut error. Overshoot occurs due to the unequal rise time of the chroma and luma inherent in the YPbPr signal.

Use the Horizontal filter setting to monitor for out-of-gamut errors within a single horizontal line using a low-pass filter (SD: < 1 MHz, HD: < 1.2 MHz).

Use the Horizontal + Vertical filter setting to monitor for out-of-gamut errors on three consecutive horizontal lines, with a weighting of 25% for the first and third lines and 50% for the second line. Use this setting to accept horizontal artifacts, making the detection symmetrical in the picture domain.

Area Masking. This feature lets you set the percentage of the total image pixels

(up to 10%) that can be outside the current gamut limits, yet not be reported as a gamut error. The Area setting does not affect bright-up in the Picture display.

Line Select Mode

Use Line Select mode to select one line of the video signal to display and measure. Line Select stays active as you change between major modes. This enables you to select a line in Picture mode, and then go to other modes to view the same line.

The selected line is highlighted in Picture mode and in the thumbnail picture.

The external picture monitor signals also contain a bright-up if enabled in the

Video Inputs/Outputs submenu of the Configure menu.

NOTE. Line Select mode is automatically disabled when Field sweep is selected.

Line Select mode is always enabled in Data mode.

Field Selection

The Field and Next Field soft keys select the field from which the selected line/sample is taken. Select All Fields to display the same line number from all fields in a frame. The 1 of 2 selection lets you choose a line from only one field in a frame. Touch the Next Field soft key repeatedly to cycle through the fields in a frame.

Sample Selection

Sample Select determines what portion of the video line is viewed in Data

Display mode (WFM700M only). Sample Select is also active in Picture and thumbnail modes to allow correlation of events between modes.



Reference

Logging

The instrument contains two different log files: diagnostics and events. You can use the Remote Web Server interface to download the contents of either log file.

Diagnostics Log

This log contains the results of the last diagnostic test that was performed.

Event Log

The instrument maintains an event log in which every entry is time-stamped with the time-of-day when the instrument logged the event. When you enable

Timecode in the Video Inputs/Outputs submenu of the Configure menu, events are time-stamped with the timecode embedded in the video signal.

CAUTION. The time-of-day time stamps in the Event Log are based on the system time of the instrument when the logging process starts. If you update the system time of the instrument while the Event Log is in the Running mode, the time stamps will not start using the new system time setting. You must stop and restart the Event Log before the time stamps will use the new system time.

Controlling the Size of the Event Log. The event log can contain up to 10,000 entries. Recording each individual event separately would quickly fill the log.

To handle this problem, the instrument classifies log entries as one of the following:

H Single shot. One isolated occurrence is logged as one entry.

H Continuous. Uninterrupted sequence of occurrences is logged as two entries marking the beginning and end of the sequence.

H Intermittent. Interrupted sequence of closely spaced occurrences can be logged as separate entries or as one entry. Use the Printing/Event Log submenu of the Configure menu to set the event log storage mode:

H Log for Duration. Logs intermittent events as one event to save space in the event log.

H Log for Resolution. Logs intermittent events separately, which preserves time stamp information for each event, but quickly fills up the event log.

By default, most of the possible alarms are enabled for logging. Use the

Configure Alarms submenu of the Configure menu to limit the number of monitored error conditions.


Reference

Configuring the Event Log Full Condition. Use the Printing/Event Log submenu of the Configure menu to configure the instrument to either stop logging events or to overwrite events when the event log has filled up to the 10,000 entry level.

Viewing and Printing the Event Log. You can view the Event Log using the Status menu or using the Remote Web Interface. In the Status menu, use the Configure

View Filter soft key to show only the events you want to view.

NOTE. The Log Filter menu settings only affect how you view the log entries using the Status display. These settings do not affect the actual contents of the

Event Log, nor do they affect the Event Log display when you use the Remote

Web Interface to view the Event Log.

The contents of the Event Log cannot be recovered after the log has been erased.

The Event Log uses icons to indicate the type and duration of detected signal conditions. Table 3--4 shows the icons you may encounter as they appear on-screen and in the Event Log file downloaded using the Remote Web Interface.

Alarm Status Displays

The instrument provides the following five alarm status displays which correspond to the categories of alarms provided in the Configure menu: general, serial, audio (Option DG only), auxiliary data, and physical (WFM700M only).

An “X” appears in the Enabled column for each of the enabled alarms. The

Status column indicates the status of each alarm, whether or not that alarm condition has been enabled. Table 3--5 lists the status indicators that may appear.

Description

No alarm condition is detected.

Indicates whether or not a condition was detected.

An alarm is detected and information about the error is displayed.

The alarm condition does not apply to the current configuration. For example, the RP165 EDH status alarm is set to

N/A when an HD signal is present because RP165 is only valid in SD signals.

An optional feature is not present in the input signal. For example, the RP165 EDH status alarm is set to Missing when the input is SD but there are no RP165 packets present in the signal (EDH is an optional signal feature).

In the Audio Alarm Status display, this indicator may appear to show which audio channels have errors. For example,

----34----78 would be displayed to indicate that channels 3, 4, 7, and 8 have errors.

This indicator is logical, after remapping, and not physical.

RGB and Composite Gamut Error Indicators. When RGB and/or Composite

Gamut errors are detected, the associated lines in the Alarm Status display have characters that indicate which gamut threshold(s) are exceeded for each component. Table 3--6 lists the error codes that may be displayed.

Reference

Vector Mode

Press the VECTOR button to enter the Vector mode, where you can select two related displays: Vector and Lightning. Both displays have targets for determining conformance using 75% or 100% color bar signals.

NOTE. Refer to the reference document A Guide to Standard and High-Definition

Digital Video Measurements at the Tektronix, Inc. Web site (www.tektronix.com) for information about how the Vector and Lightning displays are created.

Vector Display

The Vector display allows you to view the signal as a complex vector of color components, with no luminance information included. The display is a traditional vector plot of the color difference signals Pb and Pr. The radial magnitude represents saturation and the phase angle represents hue. With the Vector display, you can check the encoder accuracy for both phase and amplitude errors.

Vector Graticules. You can use the Vector menu to select either a component or composite vector graticule. When the component graticule is selected, you can turn the compass rose graticule and the I/Q axis on or off using the Grat / Gamut

Default Setup submenu in the Configure menu.

NOTE. The component vector graticule is provided to allow comparison with other equipment with similar displays. For a more accurate representation of hue shift, use the composite vector representation.

Each chrominance vector of a Color Bar signal terminates as a bright dot in a target. The distance from the center box to the target box corresponds to the amplitude for the color being measured. The dot brightness corresponds to the duration of the color bar. The dimension of each target box represents 2%

(

±14 mV) of a 700 mV amplitude.

The dashed-vector line labeled “I” is for evaluating flesh tones. Increasing radial amplitude along this axis indicates increasing flesh-tone saturation. Increasing angle change from this axis indicates increasing flesh-tone hue change.


Reference

Vector Timing Measurements. In the composite domain, the transitions between the vector end points display timing differences. Because these timing differences include the delay in the decoder output filtering, you can usually ignore them. In the component domain, there is no decoding required. Therefore, the color bar transitions contain useful timing information. These timing differences appear as looping or bowing of the transitions. While the Vector display allows you to visualize interchannel timing errors, use the Lightning display to quantify the amount of timing error.

Lightning Display

The Lightning display is a Tektronix, Inc. proprietary display combining a vertical luminance axis with horizontal chrominance information. The Lightning display plots the color difference signals, Pb and Pr, with the luminance (Y) signal. In the top half of the Lightning display, Pb is plotted against Y, and on the bottom half, Pr is plotted against inverted Y. The vertical center is the 0 V or black-clamp point.

Lightning Graticule. The Lightning graticule (see Figure 3--13) has two sets of small cross-hairs that bisect the green-magenta transitions on a color bar signal.

The calibration of the marks is shown in Table 3--7. The electronic graticule eliminates the effects of CRT nonlinearity.

You can adjust the vertical and horizontal gain using the Gain menu and the

Sweep menu to normalize signal amplitude and to expand the scale of the display to better view the small timing graticule cross-hairs.

Reference

Luminance Gain Measurement. The signal is driven along the vertical axis above and below the center box by the luminance signal. The luminance gain is correct when the center dot (clamped black level) is centered in the target box and the positive and negative excursions end at the top and bottom of the graticule.

Perfect monochrome signals appear as a thin vertical line. Any deviation or bending off the center line indicates a color variation from the monochrome setup of the display monitor.

Interchannel Timing Measurement. The scale (sequence of dots) between the green and magenta targets provides a way to check interchannel timing (CH-2 to CH-1 and CH-3 to CH-1) or signal delay. If the color difference signal is not coincident with luminance, the transitions between color dots will bend. The amount of this bending represents the relative signal delay between luminance and the color difference signal. The upper half of the display measures the Pb-to-Y timing, while the bottom half measures the Pr-to-Y Timing. If the transition bends in toward the vertical center or black region, the color difference signal is delayed with respect to luminance. If the transition bends out toward white, the color difference signal is leading the luminance signal.

Figure 3--13 shows a signal with proper interchannel timing. In Figure 3--14, the

Lightning display shows that the signal has Y--Pb and Y--Pr timing errors.

Pr and Pb Gain Measurement. The horizontal deflection of the top half of the display is an indication of the Pb gain and the lower half indicates the Pr gain. If the color bar signal dots are within the horizontal dimensions of the appropriate graticule targets, the Pb and Pr gains are within 2% of the correct amplitude.

Since the vertical and horizontal dimensions of the graticule target boxes indicate

2% luminance and color difference gain errors, respectively, you can evaluate each color bar for encoding accuracy with these limits.


Reference

Waveform Mode

Press the WFM button to enter the Waveform mode. In Waveform mode, the selected components are displayed in a voltage versus time plot. You can apply flat or low pass filters and choose the color space modes (such as RGB or composite). In component color space modes, you can turn the individual components on or off.

Parade / Overlay

In Parade mode, all selected components of the signal are displayed from left to right, in the same order as they appear on the soft key (for example, in the RGB display, “R” is on the left, followed by “G” and then “R”). In Overlay mode, all selected components of the signal are overlaid.

Configuration

Use the Video Inputs/Outputs submenu of the Configure menu to modify the waveform by turning the EAV/SAV stripping on and off. Use the Grat / Gamut

Default Setup submenu of the Configure menu to select the graticule units used in the waveform display (mV, IRE, or % full-scale).

Secondary Modes

You can use the following secondary modes while in Waveform mode:

Gain. Use the Gain menu to adjust the vertical gain of the signal display.

Cursors. Use the cursors to measure time and amplitude.

NOTE. Do not use the time cursors to measure time between components in a paraded waveform display. Parade mode is a special display format that represents all displayed components in a single screen, irrespective of the time relationship between components.

Line Select. Use the Line Select function to select part of the video signal to display and measure.

Freeze. Use the Freeze feature to capture (freeze) the active signal and compare the frozen signal to the live signal.


Reference

Sweep. Use the Sweep menu to select from the following sweep modes:

H Line. One horizontal line is displayed. Use the Line Select function to choose one line out of a field or frame.

H 2 Line. (Overlay mode only) Two consecutive horizontal lines are displayed.

H Field. All lines for one video field are displayed.

H 2 Field. (Overlay mode only) All lines for two video fields are displayed.

H Mag. Turns the Mag function on and off.

NOTE. In waveform mode, the instrument does not maintain separate sweep settings for the different color space selections. Changing the sweep selection in one color space setting changes the sweep mode in all color space settings.

The composite color space does not support 2 Line and 2 Field sweeps.

Time/div varies with format and sweep type to keep the displayed waveform a reasonable size.

Mag Sweep

When Mag sweep is on, the horizontal scale is magnified about the center of the screen. In the magnified mode, the waveform extends off both sides of the CRT.

Use the horizontal position knob to pan left and right on the waveform.

NOTE. Timing cursors operate correctly in the magnified mode, although one or both may be off screen during measurements.

When operating in two line sweep mode, MAG factors are chosen that optimize the evaluation of the horizontal blanking interval. To utilize this feature, perform the following steps:

1.

Ensure that the waveform display is in OVERLAY mode.

2.

Select 2LINE sweep.

3.

Use the horizontal position control to adjust the waveform so that the blanking interval is aligned with the horizontal graticule indicating the center of the screen.

4.

Select MAG sweep.


Reference

Measuring Relative Timing

Between Two Serial

Component Signals

To measure the timing of two digital signals, use the following procedure:

1.

Connect the two terminated SDI signals to be measured to Input A and

Input B on the waveform monitor.

2.

Select Input A to display on the waveform monitor.

3.

Verify that the waveform monitor is externally referenced to a black burst or tri-level sync signal (as appropriate).

4.

In the Video Inputs/Outputs submenu of the Configure menu, set Strip

EAV/SAV to Pass. This mode allows the 3FF, 000, 000, and XYZ values to be displayed on the waveform monitor as shown in Figure 3--15.

NOTE. The transition from 3FF to 000 and 000 to XYZ produces ringing on the display when passed through the appropriate SD or HD filter. The SAV or EAV pulse can be used as a timing reference by positioning it on a major tick mark of the waveform graticule display and comparing it to the other SDI signals, ensuring that they are positioned at the same mark.

There are no vertical pulses in the digital domain; digital systems calculate their video position based on the values of F, V, and H. Therefore, a reference point must be defined in order to measure vertical timing. For simplicity, the first line of active video can be used as the reference, because the vertical blanking lines are normally blank.

5.

To measure vertical timing, perform the following steps: a.

Set Line Select and Sweep for two-line mode.

b.

Select Field 1 and set Line Select at the setting that will display the last line in the vertical interval and the first line of active signal (Input A).

The Line Select setting should be line 20 for 1080 Interlaced HDTV,

41 for 1080 progressive formats, 25 for 720 progressive, 19 for 525 interlace, or 22 for 625 interlace. If necessary, adjust the vertical timing of the signal source until the display is correct.

c.

Select Input B and make sure the last vertical and first active lines are displayed. If necessary, adjust the vertical timing to align both vertical positions to the start of active video.

d.

Switch back to Input A and set MAG to ON, noting the amplitude of the

SAV pulses.

e.

If the amplitudes of both pulses are identical, they are in the same field.

If not, the two signals are in opposite fields and timing adjustments should be made to align the sources to the same starting point.


Reference

Figure 3- 15: XYZ pulse of Y channel with pass through selected

6.

To measure horizontal timing, perform the following steps: a.

Switch to Input A and set the waveform monitor to one line sweep.

b.

Use the horizontal position knob to set the SAV pulse to a major graticule tick mark, or use cursor mode and set a cursor on the SAV pulse.

c.

Compare the timing to the signal on Input B by selecting Input B and adjusting the fine timing controls to match the timing position of

Input A.
