MTG100 & MTG300 MPEG Generator Service Manual
4Ć5
This test verifies that transport stream data is output correctly from the ASI OUT
connector on the MPEG generator. The following equipment and MPEG test
signal is required for this test:
H Oscilloscope
H MPEG test system
H 75 W BNC cable
H 75 W to 50 W minimum loss attenuator
H test64.trp MPEG test signal
Perform the following procedure to verify that transport stream data is output
correctly from the ASI OUT connector on the MPEG generator:
1. Connect the ASI OUT connector on the MPEG generator to the oscilloscope
CH1 input using a 75 W BNC cable and the 75 W to 50 W minimum loss
attenuator as shown in Figure 4-3.
2. Set the oscilloscope controls as indicated below:

3. 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.
4. Press the START/STOP button on the MPEG generator to start the signal
output of the test64.trp file.
