H 75 W BNC cable
H Custom 9-pin to 25-pin, D-type interface cable
H 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
