Waveform display

Dynamic Range setting.

The pop-up menu for the Waveform display now contains

a selection for setting the Dynamic Range as shown below.

NOTE.

When HDR or HDR Full is selected, you can use the Left / Right

arrow keys to toggle the vertical scale of the graticule between NITS, STOPS,
REFLECTANCE and CODE VALUE. The selected scale is shown at the bottom
of the display. (See Figure 5.)

The following settings are available:

SDR (Standard Dynamic Range)

. Use this setting for conventional SD,

HD and 3G signals using ITU-R BT.709/2020 with OETF (Optical to
Electrical Transfer Function) gamma of 0.45 and with a display gamma EOTF
(Electrical to Optical Transfer Function) of 2.4 as de

ned in ITU-R BT.1886.

When SDR is selected as the dynamic range, the CONFIG > Graticules and
Readouts menu contains the following graticule settings:

STD

. The Standard graticule is available in either millivolts (Normal) or

Percent and can be con

gured within CONFIG > Graticules and Readouts

> SDI Waveform Graticules.

NARROW

. The Narrow graticule uses a NITs graticule scale and code

values, which is the traditional signal representation. This setting provides
a signal representation using a code value of 64 decimal (10-bit) equal to
0 mV or 0%, and a code value of 940 decimal (10-bit) equal to 700 mV
or 100%.

FULL

. The Full graticule uses a NITs graticule scale and code values that

provides signal representation with a code value of 4d decimal (10-bit)
equal to 0%, and a code value of 1019 decimal (10-bit) equal to 100%.

NOTE.

In SDI signals, the code words 0-3d and 1020-1023 are excluded and

clipped from a

le that uses 0-1023 as the full range as de

ned in ITU-R

BT2100.

HDR (High Dynamic Range)

. Use this setting if you need the bit depth to

more ef

ciently produce smoother blacks and brighter specular highlights.

When HDR is selected as the dynamic range, the CONFIG > Graticules and
Readouts menu contains the following graticule settings:

HLG(1200)

. The Hybrid Log Gamma (HLG) graticule is de

ned in

standard ARIB STD B-67 and was developed by the BBC and NHK.
SMPTE standard ST 2084 de

nes High Dynamic Range Electro-Optical

Transfer Function of Mastering Reference Displays also know as
Perceptual Quantization (PQ).

ST2084(1K)

. This graticule uses the ST 2084 curve with a maximum

value of 1000 Nits using the narrow range.

ST2084(2K)

. This graticule uses the ST 2084 curve with a maximum

value of 2000 Nits using narrow range.

ST2084(4K)

. This graticule uses the ST 2084 curve with a maximum

value of 4000 Nits using narrow range.

ST2084(5K)

. This graticule uses the ST 2084 curve with a maximum

value of 5000 Nits using narrow range.

ST2084(10K)

. This graticule uses the ST 2084 curve with a maximum

value of 10000 Nits using narrow range.

NOTE.

Narrow range is de

ned by ITU-R BT.2100 as signal representation

with code value 64 decimal (10-bit) equal to 0 mV or 0%, and code value 940
decimal (10-bit) equal to 700 mV or 100%.

HDR Full (High Dynamic Range Full)

. Use this setting if you need the

High Dynamic Full Range de

ned by ITU-R BT.2100, which provides signal

representation with code value 4d decimal (10-bit) equal to 0%, and code
value 1019 decimal (10-bit) equal to 100%.

NOTE.

In SDI signals, the code words 0-3d and 1020-1023 are excluded and

clipped from a

le that uses 0-1023 as the full range as de

ned in ITU-R BT2100.

When HDR Full is selected as the dynamic range, the CONFIG > Graticules
and Readouts menu contains the following graticule settings:

ST2084(1K) Full

. This graticule uses the ST 2084 curve with a maximum

value of 1000 Nits using full range.

ST2084(10K) Full

. This graticule uses the ST 2084 curve with a

maximum value of 10000 Nits using full range.

Camera Log

. Use this setting to use a graticule with a curve based on the

camera manufacturers speci

cation. When Camera Log is selected as the

dynamic range, the CONFIG > Graticules and Readouts menu contains the
following graticule settings:

S Log

. This graticule uses the Sony S Log curve.

S Log2

. This graticule uses the Sony S Log2 curve.

S Log3

. This graticule uses the Sony S Log3 curve.

C Log

. This graticule uses the Canon C Log curve.

Log C

. This graticule uses the ARRI Log C curve at (ISO) El 800.

BT.709

. This graticule uses the traditional ITU-R BT.709 representation.

HDR graticule selection.

The CONFIG > Graticules and Readouts menu now

contains a setting for selecting the HDR graticule to be used by the Waveform
display: HLG(1200), ST2084 (1K), ST2084 (2K), ST2084 (5K), or ST2084
(10K).

HDR graticule vertical scale setting.

When an HDR graticule is selected for the

Waveform display, you can use the Left / Right arrow keys to toggle the vertical
scale units between NITS, STOPS, or REFLECTANCE. Camera operators can
use the graticule lines at 2%, 18% or 90% Re

ectance to properly setup camera

exposure with a camera test chart of 2% black, 18% gray and 90% white.

Figure 3: Waveform display showing the HDR graticule with NITS selected as the vertical scale

Gain adjustment.

When the ST.2084 (1K) or ST.2084 (10K) HDR graticules are

selected, a

xed zoom mode from 100 Nits to maximum scale is available by

using the Up arrow key to enable Zoom Mode and the Down arrow key to disable
Zoom Mode. When Zoom Mode is enabled, the Gain function and the Vertical
Position controls are locked in a

xed con

guration. When in HDR modes,

Variable Gain will be enabled by default to facilitate the Zoom mode function.

Voltage cursors.

When HDR or HDR Full mode is selected as the Dynamic

Range setting, the mV voltage measurement cursors are replaced by a set of Nits
measurement cursors.

Picture display brightup

settings

The CONFIG > Display Settings > Picture Brightup on Luma Gamut Error menu
has new selections for HDR monitoring.

Off

. For this setting, the highlight overlay is turned off in the picture display.

Luma

. For this setting, the highlight overlay is turned on for Luma values

that exceed signal levels based on gamut thresholds for luma settings.

HDR Specular On

. For this setting, the highlight overlay is turned on for

selected HDR settings and produces HDR zebra highlights in the picture for
large areas of the trace that exceed 100 nits.

NOTE.

The HDR zebra highlighting allows users to verify the location and the

size of the specular highlights.

HDR Specular Full On

. For this setting, the highlight overlay is turned on

for HDR Full settings and produces HDR zebra highlights in the picture for
large areas of the trace that exceeding 100 nits.

Audio Loudness

Session reset using the

GPI interface

There is a new Loudness Session Logging setting in the CONFIG > Utilities >
Ground Closure Mode menu that allows you to con

gure the GPI interface

(REMOTE connector) to reset the Audio Loudness Session and to note the reset
in the Loudness Trigger Log.

When a selected pin on the REMOTE connector is grounded (See Table 1.),
the Audio Loudness Session will save the values of the loudness measurement
parameters in the Loudness Trigger Log. The loudness meter will then be reset
and begin a new measurement when the GPI trigger is released.

Use the Tektronix WFM Remote Interface to view the Loudness Trigger Log.

Trigger events.

There are three trigger events that can be used to reset the Audio

Loudness Session:

Start Commercial 1:

Use this GPI trigger to reset the Audio Loudness

Session when a commercial program is provided and to indicate the
commercial program in the Loudness Trigger Log.

Start Program 1:

Use this GPI trigger to reset the Audio Loudness Session

when a main program is provided and to indicate the main program in the
Loudness Trigger Log.

Pause Monitoring Channel 1:

Use this GPI trigger to reset the Audio

Loudness Session when monitoring is paused and to indicate the pause in
the Loudness Trigger Log.

Use only the Channel 1 trigger events when the CONFIG > Input Mode is
con

gured to Single mode. When the CONFIG > Input Mode is con

gured to

Simultaneous, you can also use the Channel 2 trigger events to reset the Audio
Loudness Session for the secondary channel.

ITU-R BT.2020 color space

There is a new ITU-R BT.2020 setting in the CONFIG > SDI Input > HD
Colorimetry menu that allows you to monitor the BT.2020 color space for HD
formats. When the HD Colorimetry is set to ITU 2020, the targets on the Vector
and Lightning displays shift slightly to conform to the BT.2020 color space and
the gamut measurement limits also change.

If the colorspace is set to AUTO, the instrument will select BT.2020 if signalled
in the VPID.

HD colorimetry readout

The Video Session display has a new readout to indicate the current HD
colorimetry setting (CONFIG > SDI Input > HD Colorimetry).
