4Ć14 MTG100 & MTG300 MPEG Generator Service Manual
This test confirms that the external clock input (ECL CONTROL input) on the
MPEG generator is functioning correctly. The following equipment and MPEG
test signal is required for this test:
MPEG test system
75 W BNC cable
Custom 9-pin to 25-pin, D-type interface cable
test40.trp MPEG test signal
Perform the following procedure to verify that the external clock input
(ECL CONTROL input) on the MPEG generator is functioning correctly:
1. Use the 75 W BNC cable to connect the ASI OUT connector on the MPEG
generator to the ASI IN connector on the rear panel of the MPEG test system
as shown in Figure 4-9.
2. Use the custom interface cable (see Figure 4-1 on page 4-2) to connect
the ECL CONTROL connector on the MPEG generator to the ECL
PARALLEL/SERIAL I/O connector on the MPEG test system rear panel as
shown in Figure 4-9.
3. Open the test40.trp file on the MPEG generator.
a. Select Open TS File... from the FILE pull-down menu.
