Firmware Update 5.6
November 30, 2011

This document describes new features, improvements, and limitations
of firmware version 5.6 for the TG700 Signal Generator Platform.

New Features
------------

This release adds support for the new SDI7 2-Channel SD/HD/ 3Gb/s
SDI Video Generator Module.

The SDI7 module can be operated as a signal generator to output
two channels of 270 Mb/s SD-SDI, 1.5 Gb/s HD-SDI and 3 Gb/s SDI
video test signals in a varaiety of formats, including both Level A
and Level B mapping structures for 3G-SDI signals.

GENERAL LIMITATIONS
-------------------

This release has the following general limitations:

TG700 Mainframe Memory Requirements:

With software version 5.6, the TG700 mainframe must have at least
32 MB of memory installed.  If you intent to install frame picture
files (*.pic), created by the Frame Picture Generator application
for the DVG7, HDVG7, AVG7 or AWVG7 modules, or if you intend to
install bitmap frame picture files (*.bmp) for the SDI7 module,
then the mainframe must have 64 MB of memory installed.

Software Upgrades:

If your existing mainframe has 32 MB of memory and you have loaded
the TG700 memory with signals from the Frame Picture Generator
application, you may not be able to upgrade the instrument to
software version 5.6.

If you receive a memory error while attempting to upgrade the
software version, you need to either delete some of the frame
picture files or upgrade your instrument to 64 MB of memory.

Memory Upgrades:

------------------------------------------------------------------
NOTE: Option FP provided extra memory, which allowed the TG700
mainframe to support frame picture images.  This option is no
longer necessary for new TG700 mainframes.

If you have an older mainframe with less than 64 MB of memory,
you can increase the memory in your mainframe to 64 MB by ordering
the following upgrade kit:  040-1698-xx.  Contact your local
Tektronix representative for more information.
------------------------------------------------------------------

TG7 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.

TG7 Comm Software:

- Do not change or delete any file names or folder names other than
those downloaded by users (signal files, sequence files, and preset
files). Doing so can cause the instrument to operate in an
unexpected manner.

You can change the names of user files (signal files, sequence
files, and preset files) after you have downloaded them into the
TG700 mainframe.  Remove and reapply power to see the updated names
on the mainframe.

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.

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 signal button of 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.

Embedded Audio of the HDVG7 Module:

- Embedded audio for 720 23.98p/24p formats is not supported for the
HDVG7 module, even though it 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 Converter 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 Formats 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.

Multiple Timecode Formats:

- Frequent changes to output formats can result in instability on
those outputs. Disturbances to PAL output signals can be prevented
by setting any output to PAL as a power-on preset, and then keeping
any output set to PAL at all times.

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 then switching back to converter
mode.

- The trigger output cannot generate a frame pulse or a line pulse
when the module is in converter mode.

- The moving picture and video component functions do not apply to up-
converted output signals.

Embedded Audio of the HD3G7 Module:

- 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
onto both  virtual links.  Therefore, up to 32 channels of embedded
audio can appear on the 3 Gb/s 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 trilevel 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).

Closed Caption Data with the HD3G7 Module in Converter Mode:

- The HD3G7 module does not re-format SMPTE 334 Caption Distribution
Packets in converter mode. Therefore, when up-converting from 1080i
59.94 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 Module:

- 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 3G 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.

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.

Test Signal Files of the HD3G7 Module:

- The HD3G7 module now uses file-based test signal definitions.  If
you modify a signal from the factory version, unpredictable results
may occur.  To recover from this situation, reload the factory
version of the signal file from the "TG700 Software Library and
Documentation DVD" that was supplied with the instrument.

HD3G7 Module Presets

- If a preset was made with an earlier version of the HD3G7 module and
recalled with version 5.6, the test signal selection is not
restored.  All other settings are restored normally.

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.

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
assure 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 a 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.

If the TOD source is set to "Internal" when the instrument is
powered on, you will need to change the TOD source to "VITC Input",
"LTC Input", or "GPS Signal" and then back to "Internal" in order
to enable the DST scheduler system with "Internal" as the TOD
source.  Check the system time of day and adjust as needed to
ensure that it is correct before enabling the DST schedule in
"Internal" mode.

DHCP Service on Instrument Power-up:

- When the instrument is configured for DHCP service and then is
powered down, the service may not always restart automatically
when the instrument is powered up.  If this is the case, use the NET
SETUP subment to first disable DHCP, and then to immediately
re-enable DHCP.

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.

SDI7 Response Time:

- The response time for loading a frame picture or logo display, or
for loading text and/or circle overlays will vary depending on
the size of the picture/data file and the number of characters in
the text overlay.

Multiburst Signal Motion:

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