4Ć12 MTG100 & MTG300 MPEG Generator Service Manual
This test confirms that transport stream data is output correctly in serial format
from the ECL/TTL/LVDS OUT connector on the MPEG generator. The
following equipment and MPEG test signal is required for this test:
MPEG test system
Parallel interface cable
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 ECL PARALLEL/SERIAL I/O
connector on the MPEG test system rear panel as shown in Figure 4-8.
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 : Serial 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.
6. Verify that the following LEDs on the MPEG generator’s front panel are
illuminated: PLL, BUFFER, and HDD.
