Operating Information

Operating Basics

Overview

This chapter provides basic operating information for the WVR610A &
WVR611A Waveform Rasterizers.

The WVR610A & WVR611A use 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. See Figure 2--1.
To enable the tiles to function independently, most of the controls only affect one
tile at a time. The tile that is currently being controlled is considered the active
tile and it is indicated on the display by a light-blue outline around the tile. The
active tile is indicated on the front panel by the lit display select button on the
left side of the front panel.

Figure 2- 1: A display with all four tiles visible

The waveform rasterizer can also display one tile at a time. If, for example, you
want to display just the Waveform tile to make a rise time measurement, you can
press the FULL button to display a tile in full-screen mode. See Figure 2--2.

Operating Basics

Figure 2- 2: A t ile in full-screen mode

The waveform rasterizer can display measurements in multiple tiles simulta­neously. See Figures 2--3 and 2--4. For example, you can display all four Status
screens at one time. The only measurement that cannot be displayed in more than
one tile is the Audio measurement. It can be displayed in only one tile at a time.

Operating Basics

Three Levels of Control

Figure 2- 4: A display with multiple WFM displays

You control the waveform rasterizer on three levels:

H Frequently-changed settings

H Tile-specific settings

H Instrument-wide settings

Frequently changed settings. The front-panel buttons control the most commonly
changed parameters, such as which measurement appears in each tile. The knobs
are used to adjust levels and make selections.

Tile-specific settings. Pop-up menus control parameters that are specific to the tile
in which they are displayed. The pop-up menus control less frequently changed
parameters such as the waveform display mode (for example, changing the
waveform display mode from RGB to YPbPr). To display a pop-up menu, press
and hold the desired MEASURE SELECT or DISPLAY SELECT button for
about a second.

Instrument-wide settings. The parameters in the Configuration menu are
instrument-wide settings. The configuration menu controls settings that are
changed only occasionally, such as changing waveform color or setting the
network address.

Operating Basics

Range of Controls

Front-Panel Controls

Tile Settings

Some controls are global and affect all tiles, while other controls only affect the
active tile. Generally speaking, if a control is configured by front-panel buttons
or by a pop-up menu, then it is tile specific. Configuration selections are usually
global. Exceptions are the Input buttons, and all audio features, both of which are
global.

The following sections describe the front panel controls of the WVR610A &
WVR611A.

Each tile maintains its own settings independent of the other tiles, including
GAIN and SWEEP, and display type among others. For instance, when you
switch a tile to a different measurement, the GAIN and SWEEP settings will be
changed to what they were the last time the selected measurement was displayed
in the tile.

Display type is also independent for each tile. You could set Tile 1 to display the
Video Session STATUS screen and set Tile 2 to display the Error Log STATUS
screen. Suppose you then change Tile 1 to a WFM display and Tile 2 to a
GAMUT display. If you then change Tile 1 back to a STATUS display, it will
display the Video Session screen, which is what it was set to before you changed
it to the WFM display. Likewise, if you change Tile 2 back to STATUS, it will
display the Error Log screen.

The Waveform (WFM) display is the familiar voltage versus time display used to
view a waveform. You can view the input signal in line or field sweep. You can
choose which SDI signal elements are displayed (RGB, YRGB, or YPbPr), and
you can apply filters to the signal. You can also display an SDI input as though it
were a composite signal. Figure 2--18 identifies the elements of the Waveform
display and Table 2--3 describes the meaning of the elements of the Waveform

Picture Display

The Picture display lets you see the picture generated by the video signal. You
can choose to display the picture with or without a Picture Frame. See
Figure 2--21. The Picture Frame function allows you to display or hide elements
of the video signal outside the active video. With Picture Frame switched On,
only the active video portion of the signal is displayed. With Picture Frame
switched Off, elements of the signal outside the active video are visible. When
the picture frame is off, you can see user data, embedded audio and elements in
the vertical interval.

NOTE. In tile mode, 525 line pictures are cropped by 12 lines. Six at the top and
six at the bottom. This is done as part of the aspect ratio correction. In full-­screen mode there is no cropping.

Pictures are decimated horizontally or vertically to achieve the correct 4 x 3
aspect ratio on a square pixel computer monitor. This decimation may cause
some artifacts. This behavior may be evident on a sweep signal on 525 mode.

Above-bar Warning

Messages

In-bar Warning Messages

The WVR610A & WVR611A display warning messages above the level meter
bars. The warning messages that can appear above the bars are shown below.

CLIP. The number of consecutive samples is at or exceeds the # Samples for Clip
setting.

OVER. The signal has been at or above the specified Over Level for a time
exceeding the Duration for Over setting.

The WVR610A & WVR611A display warning messages within the level meter
bars. The warning messages that can appear are shown below in order of priority.

UNLOCKED. The instrument is not locked to an incoming signal on the indicated
input channel. Data cannot be decoded and all data and other errors are ignored.
This means that if an AES input is selected, nothing recognizable is present on
the input, or if embedded audio is selected, the VIDEO input is unrecognizable.

AES PARITY. The incoming subframe does not have even parity as specified by
the digital audio standards. The data sample is unreliable and is ignored. The
level meters and Lissajous display treat the sample as a zero sample.

AES CRC ERROR. The CRC code in the AES channel status packet is incorrect.
Sometimes the CRC code is set to zero, indicating that the signal is missing;
when this is the case, this message is not displayed.

MUTE. The number of consecutive all-zero samples is at or exceed the # Samples
for Mute setting.

SILENCE. The signal has been at or below the specified Silence Level for a time
exceeding the Duration for Silence setting.

DISABLED. Disabled can appear for three reasons:

H Analog audio is selected as the bar source, this causes bars 7 and 8 to say

DISABLED since there are only 6 analog inputs.

H Embedded audio is selected as the bar source when Composite video is

selected as the video input. Since there is no embedded audio in composite,
all of the bars will say DISABLED.

H If the currently selected audio source’s Bar to Input Map does not have all of

the bars mapped to inputs, any bars that are unmapped will say DISABLED.

The waveform rasterizer is designed 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. 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. The power source frequency is 50 or 60 Hz. The operating
voltage range is continuous from 100 to 240 VAC.

Operating Basics

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 do not have to ground the unused lead
(grounding the unused lead can reduce noise).

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.

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 six balanced outputs.

XGA Output Connector

This is the display output. The display resolution is 1024 x 768, in 16 colors.
The output is compatible with standard analog PC monitors, either CRT or

Sync AFC Speed

DC Restore

NTSC Setup

The Sync AFC Speed sets the ability of the loop to follow changes in the
external reference signal. “Fast” can track signals with more line rate variation.
“Slow” has lower jitter.

Applies a voltage to the signal to keep one point on the waveform at a fixed DC
level. This makes taking measurements easier when the DC level of the
waveform shifts due to changes in signal content. Setting choices are Fast, Slow,
and Off.

H Select Off when you wish to see the DC offset in the signal. Off cancels the

operation of the DC Restore circuitry.

H Select Slow when you wish to remove DC offset from the signal but you still

want to see hum.

H Select Fast when you want to remove the effects of hum and offset from the

signal.

The NTSC Setup setting optimizes the operation of the WVR610A &
WVR611A for NTSC signals with and without set up. For example, this setting
changes the scaling of the vector bar targets.

PAL Vector

When V+ is chosen, the phase reference of the --V lines is inverted, then shown
as an overlay on the +V lines to provide a comparison display.

Sync AFC Speed

Sets the external reference format. In Auto, the waveform rasterizer automatical­ly detects the correct format. This setting is useful when you occasionally change
the input format for the external reference signal. If you always use the same
external reference signal format, you can specify NTSC or PAL.

The Sync AFC Speed sets the ability of the loop to follow changes in the
external reference signal. “Fast” can track signals with more line rate variation.
“Slow” has lower jitter.

NOTE. When using an SDI input with an external reference, an input signal
time--base variation outside the specified range may be shown as a reference
unlock on the status bar and error logs.

Ballistics

Specifies the response characteristics of the level meters. Choices are True Peak,
PPM (Peak Program Meter) Type 1 and Type 2, and VU.

H True Peak -- Show actual signal peaks regardless of their duration. Rise

times are essentially instantaneous. Fall time is like PPM Type 2, and
requires 2.8 seconds to fall 20 dB. The in-bar peak indicator will persist at
the peak level for the “Peak Hold Time”. When True Peak ballistics are
selected, the display designation is True Peak Ballistics.

H PPM Type 1-- Response equivalent to IEC Type I (essentially the same as

DIN 45406 and Nordic N--9). The PPM Type 1 has a slightly faster attack
time and a faster return time than Type 2, requiring 1.7 seconds to fall 20 dB
as opposed to 2.8 seconds for Type II. When PPM Type 1 ballistics are
selected, the display designation is PPM Type 1 Ballistics.

H PPM Type 2--Response equivalent to IEC Type II (the same as defined in

IEEE Std 152--1991). The PPM Type 2 has a slightly slower attack time and
a slower return time than Type 1, requiring 2.8 seconds to fall 20 dB as
opposed to 1.7 seconds for Type 1. When PPM Type 2 ballistics are selected,
the display designation is PPM Type 2 Ballistics.

H VU -- A VU meter as defined by IEEE Std. 152-1991, but with an extended

dB-linear scale. The meter bars will also contain true peak indicators when
VU is selected. The display designation of this setting is VU Ballistics.

Numbers the meter scale relative to Top of Scale or to one of the two user-adjust­able levels. When the zero mark is set to either Peak Program or Test level, the
scale units are dBr, relative to the 0 dB level; units above the selected 0 dB mark
are positive, while units below it are negative.

Meter Scaling

Set Meter Type to:

Sets the maximum desired level for monitored programs. The meter bars change
to red above the Peak Program Level.

Sets as the test or “line up” level for your system. The meter bars change to
yellow between the Test and Peak Program Levels.

Sets the scaling for the level meters. Meter scaling can be set to Normal or
customized by setting up to three parameters: Custom Height, Custom Offset and
Graticule Size. At the Normal setting, the meter scale is set to a 70 dB range,
with the actual values at the top and bottom of the meter depending on the
setting for Set 0dB Mark to:. When you select one of the custom parameters, all
are enabled. When using Custom Height, the range of the meters can be set from
10 -- 90 dB. When using Custom Offset, you are setting the location of a
“window” on the bar, where the size of the window is set by the Custom Height
setting. The Custom Offset setting, in effect, moves the window up and down the
range of the level meter. The Graticule Size setting specifies the difference in dB
between graticule tic marks. The difference between tic marks can be set from
3dBto10dB,exceptforVUwhichissetat3dB.

Sets parameters defining meter characteristics to conform with audio meter types
standardized in the industry. The characteristics of each meter type are shown in
Table 2--20.

Lissajous AGC

Specifies the audio level above which the signal is considered “over”. This
setting is used to trigger on-screen indicators and alarms.

Specifies how long the audio level must be above the Over Level before an alarm
will be triggered.

Specifies the length of time the in-bar error messages are displayed after the error
has been removed.

Determines how quickly the meter reacts to changes in phase relationship. The
meter reading is actually an average of correlation over time and this setting
determines how many samples are used to calculate the average. Lower settings
result in a faster meter response. Experiment to find the setting that best fits your
needs. The default setting is 8, which is 1.5 seconds.

When On, allows the Lissajous or Phase display to change gain and keep the
display well scaled. When Off, puts the display in fixed gain mode with the Peak
Program level at the perimeter of the active area.

NOTE. The audio pop-up menu allows selection of input and allows the optional
phase display to be added to the audio tile.

Digital Audio Displays Settings

The Digital Audio Display submenu provides access to parameters that control
meter ballistics, various meter characteristics such as Peak Hold Time, the
number of consecutive samples required to trigger various alarms, and other
settings. Table 2--19 lists the settings for audio displays.
