This document describes new features, improvements, and limitations of firmware
version 1.1 for the TG8000 Multiformat Test Signal Generator.

This release includes repairs for defects found in earlier versions of the TG8000
firmware.

New features

The following new features are included in this release:

BG7 module
- On BG7 modules with Option CB, new test signals have been added including
Shallow Ramp, Convergence, Pluge and Luma Reference. In addition, PAL test
signals CCIR-17L and CCIR-18L have been added.

GPS7 module
- The capability to genlock to CW signals has been added. The module can genlock to
1 MHz, 3.58 MHz, 4.43 MHz, 5 MHz and 10 MHz reference input signals.

SDI7 module
- Burn-in time code (BITC) display can now be added to any test pattern generated
from the outputs.
- The secondary outputs can now output a test pattern or black burst signal with
the embedded audio enabled, muted, or disabled (no audio).

Mainframe diagnostics
The mainframe DIAGNOSTICS menu now includes two additional readouts:
- The number of hours that the Power Supply module has been active.
- The status of the power level in the RTC (Real Time Controller) battery.

Feature modifications

The following modifications to existing features are included in this release:

GPS7 module
- The behavior of the time-of-day controls for INTERNAL reference time has been
changed. When INTERNAL is selected as the time-of-day source, the time-of-day will
not be automatically changed. To change the time-of-day in the INTERNAL mode, the
user must enter the TIME OF DAY menu, scroll to the "Internal: yyyy-mm-dd hh:mm:ss"
display, make the change, and then press the ENTER button to confirm the change.

NOTE.  The manual time-of-day setting is not automatically reapplied when the
instrument power is cycled. If the instrument powers up in INTERNAL mode, the time
of day will be acquired from the internal real-time clock in the TG8000 generator.

- The behavior of the system time-of-day when VITC/LTC is used as the time-of-day
reference has been changed. When VITC or LTC is used as the time-of-day source,
the hh:mm:ss:ff settings will be synchronized to the VITC/LTC source (if present).
However, the yyyy-mm-dd settings will be set from the most recent valid source
(GPS or internal/manual).

SDI7 module
- The logo overlay position on test pattern outputs will not move when MOVING
PICTURE mode is enabled.

General limitations

This firmware release has the following general limitations. Please check the
Tektronix Web site (www.tek.com/software/downloads) for any firmware updates to
the TG8000 generator.

TG Setup software
- In setting signal formats for the Black 2 and Black 3 outputs of the AGL7 module,
do not select Black 2 = HD sync (same as Black 3) and Black 3 = BB (same as
Black 2) simultaneously, while Frame Reset 1 is set to 2.997 Hz. This operation
makes the Frame Reset 1 unstable. If this is the case, reset the system by recalling
the Power On Default setting or a preset.

USB port
- When you mount a USB drive, the SDI output signal from an HDVG7 module may briefly
unlock. This problem only occurs on HDVG7 modules with serial numbers B013412 or
earlier, or HDVG7 modules with a serial number that begins with the letter ‘J’.
The SDI outputs from DVG7, HD3G7, and SDI7 modules are not affected by the mounting
of a USB drive.
- The TG Setup application cannot be used for remote configuration while files are
being restored from a USB drive. Wait until the restore operation is complete before
opening the TG Setup application and connecting to the TG8000 generator.

Firmware upgrades
- When the TG8000 firmware is upgraded (using a USB drive or a network connection),
all files created or installed by the user are deleted. The deleted files include
presets, signal files, frame picture files, logo files, sequence files, and for the
SDI7 module, can also include text and font files. The standard set of factory
installed signal files, logo files, and SDI7 module font files are restored when
the firmware is upgraded.

To prevent the loss of your user created files, use the "Backup All User Data to
USB" function from the UTILITY menu to save your user files before you
upgrade the firmware. After the upgrade, use the "Restore All User Data From
USB" function from the UTILITY menu to restore your user created files.

- If you have loaded the TG8000 memory with a large number of test signals or
frame picture files, you may not be able to upgrade the instrument firmware
because the memory is too full. If you receive a memory error while attempting to
upgrade the firmware version, you need to delete some of the test signal or frame
picture files and then perform the upgrade.

Resetting an output signal
- When the instrument rereads or resets signal data, such as format changing, preset
recall, or signal-button assignment, a signal output interruption or synchronization
shock may occur.

Changing output formats with open menus
- Some front-panel menus and status displays are dependent on the frame rate of the
currently selected output format. If you open a submenu and press the FORMAT button
to change the frame rate, the submenu will not be refreshed until it is exited and
reopened.

Setting the genlock source
- If you change the frame reset period in the AGL7 module after the genlock source
is set to CW, the frame reset may not be selected properly. If this is the case,
set the frame reset to CW.

Assigning a signal and frame picture to a front-panel button
- When you assign a downloaded signal to a front-panel button, do not assign
different format signals to the same button.

Do not assign a signal set to a button that corresponds to the signal that is
currently being output. Also, do not assign a signal set to a signal button while
the message "No Signal Set Assigned" is displayed. If you reassign a signal set to
the OTHER button, perform the reassignment while a signal that is assigned to a
button other than the OTHER button is output.

Time of day changes for timecode outputs
- When the time-of-day changes, such as when scheduled daylight savings adjustments
are made or when the internal time is set from the front panel, there can be a delay
before that change is reflected on timecode outputs.

This delay may be a small number of frames (fraction of a second) when all timecode
output formats are based on the same clock rate (for example, NTSC black burst and
1080i 59.94 HD tri-level on black outputs in addition to 30 fps drop-frame on LTC
outputs), or up to several seconds when timecode formats based on different clock
rates are used (for example, 29.97 fps and 24 fps on different outputs).

Daylight Savings Time (DST) scheduler system
- The DST scheduler system applies the DST offset even if the Time-Of-Day (TOD)
source is set to "VITC Input" or "LTC Input". In both cases, the offset is
applied whether or not a valid VITC or LTC input signal is available. For proper
DST scheduling, you need to manually enter the date and time in the TOD menu and
ensure that the instrument has valid time information.

When the TOD source is set to "GPS signal" and the GPS is not locked to the input
signal, the DST scheduler system will apply the DST offset when the internal time
of day clock (which starts at fixed default and may not be correct) reaches the
time scheduled for the DST offset to be applied or removed. Ensure that the GPS
is locked and that the system time of day is correct before turning on the DST
scheduler system.

The manual time-of-day setting is not automatically reapplied when the instrument
power is cycled. If the instrument powers up in "Internal" mode, the time of day
will be acquired from the internal real-time clock in the TG8000 generator.
Check the system time of day and adjust as needed to ensure that it is correct
before enabling the DST scheduler in "Internal" mode.

Timing range of AGL7 module
- The TIMING menu for the AGL7 module will allow output timing adjustment beyond
± 1/2 frame of the current format.

Embedded audio of the HDVG7 module
- Embedded audio for 720 23.98p/24p formats are not supported for the HDVG7
module, even though they can be selected in the menus.
- The first user data word in the audio control packet (containing the Audio
Frame value) has incorrect parity when the frame count is 1, 2, or 4.

Y to GBR convertor mode of the HDLG7 module
- If the output format is 2K and the Converter mode is set to Y to GBR, changing
operating mode by selecting a test signal will cause an unexpected black and white
signal to be generated. To correct the test signal, press the OTHER button until
Normal is selected, and then press the test signal button.

25/29.97/30 Hz segmented frame format for the HDLG7 module
- The HDLG7 module does not have format selections for 1080PsF at 25 Hz,29.97 Hz,
or 30 Hz. These formats are almost identical to 1080i (interlaced) formats at
50 Hz, 59.94 Hz, and 60 Hz respectively; these format settings can be used with
progressive segmented signals. However, note that the SMPTE 352M payload
identifier for the output signal will show an interlaced signal format, even when
the HDLG7 module is converting a single link progressive segmented input signal to
dual link.

Converter mode of the HD3G7 module
- Infrequently, the module will fail to up-convert the input HD-SDI signal. If no
output is seen, the problem can be corrected by selecting a different test signal
and then switching back to converter mode.
- The trigger output cannot generate a frame pulse or line pulse when the module
is in converter mode.
- The moving picture and video component functions do not apply to up-converted
output signals.
- When a Level B format is selected for the up-converted 3 Gb/s output signal,
embedded audio from the input HD-SDI signal will be copied into both virtual links.
Therefore, up to 32 channels of embedded audio can appear on the 3 Gb/s output.
- The HD3G7 module does not reformat SMPTE 334 Caption Distribution Packets in
converter mode. Therefore, when up-converting from 1080i59.94 Hz to 1080p 59.94 Hz,
for example, the output will contain CDP data in alternate frames, each with
40 bytes of caption data, instead of CDP data in every frame, each with 20 bytes
of caption data.
- Up-conversion to a Level B fast progressive format may result in mis-ordered
Caption Distribution Packets in the stream of output frames.

SDI equalizer test signal of the HD3G7 and SDI7 modules
- Per SMPTE RP198 for HD-SDI, a polarity change word is used to ensure equal
probabilities of the DC bias for the equalizer test pattern. However, some SDI
formats still exhibit an unequal bias. Enabling a dynamic bit stream in the
output signal, such as embedded audio or timecode data, will result in both DC
levels appearing in the output signal.

Test signal files of the HD3G7 and SDI7 modules
- The HD3G7 and SDI7 modules use file-based test signal definitions. If you
modify a signal file from the factory version, unpredictable results may occur.
To recover from this situation, reload the factory version of the signal file
from the TG8000 SW Library and Documentation DVD that was supplied with
the instrument.

SDI7 multi-language support
- Languages that require combined glyphs in order to be represented may not be
correctly rendered in the Text ID display on the SDI7 module.

Multiburst signal motion on the SDI7 module
- Do not set a Multiburst signal in motion on the SDI7 module. Otherwise, a
corrupted signal will be generated.
