SDI7 module troubleshooting
Download a frame picture
with a known good image
If you are havin
g problems with generating a frame picture with the SDI7 m odule,
perform the following steps to install a known good frame picture so that you can
determine whether the problem is with the signal you were trying to generate or
with the module:
1. If necessary, install the TGComm application on your PC. You can install
the software from the TG8000 SW Library and Documentation DVD
that was shipped with the instrument or from the Tektronix Web site
(www.tektronix.com/software).
2. Use the TGComm application to download one of the sample frame pictures
from the TG8000 SW Library and Documentation DVD. The sample images
are locat
ed in the SAMPLE/SDI7 directory on the DVD.
NOTE. The images are provided in subdirectories named after the native
resolutions for 525, 625, 720, and 1080 line systems. For general testing, load a
1080 x 1920 image. The color bar frame picture s provide a known signal and are
available in most sizes.
3. Config
ure the SDI7 module to output a 1080i 59.94 format HD signal.
4. Press the OTHER button to access the frame picture menu, a n d then u se the
left a
nd right arrow buttons to select the file you downloaded from the DVD.
Press the ENTER button to load that signal into the generator.
5. Chec
k to see if the SDI7 module is outputting a proper frame picture:
If the SDI7 module generates a frame picture with the signal downloaded
fro
m the DVD but does not when using a customer signal, then the
problem is probably something in the customer signal.
If
the SDI7 module does not generate a frame picture with the signal
downloaded from the DVD, then there i s probably a problem with the
SDI7 module.
