Release notes
General limit
ations
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 Bla ck 3) and Black 3 = BB (same as
Black 2) si
multaneously, 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 s erial number that
begins with the letter ‘J’. The SDI outputs from DVG7, HD3G7, and SDI7
modules are not affected by the m ounting 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
TG80
00 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
file
s include presets, signal files, frame picture fi les, 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 u ser create d files, use the “Backup All User Data
to USB” function from the UTILITY menu to save your user files before y ou
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 a nd then perform the upgrade.
Resetting an output signa l
When the instrume nt rereads or resets signal data, such as format c hanging, preset
recall, or signal-button assignment, a signal output interruption o r synchronization
shock may occur.
