This test confirms that transport stream data is output correctly in parallel format
from the ECL/TTL/LVDS OUT connector on the MPEG generator. The
following equipment and MPEG test signal is required for this test:
H MPEG test system
H Parallel interface cable
H test64.trp MPEG test signal
Perform the following procedure to verify that transport stream data in parallel
format is output correctly from the ECL/TTL/LVDS OUT connector on the
MPEG generator:
1. Use the parallel interface cable to connect the ECL/TTL/LVDS OUT
connector on the MPEG generator to the LVDS/ECL/RS422 Level In
connector on the MPEG test system rear panel as shown in Figure 4-7.
2. Open the test64.trp file on the MPEG generator.
a. Select Open TS File... from the FILE pull-down menu.
b. In the resulting Select TS File dialog box, select the test64.trp file, and
then press the OK bezel button.
3. Select Level : ECL from the OUTPUT menu on the MPEG generator, and
then press the OK bezel button.
4. Select Interface : Parallel from the OUTPUT menu on the MPEG
generator, and then press the OK bezel button.
5. Press the START/STOP button on the MPEG generator to start the signal
output of the test64.trp file.
