3. Open the test40.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 test40.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 test40.trp file.
5. Verify that the following LEDs on the MPEG generator’s front panel are
illuminated: PLL, BUFFER, and HDD.
6. Use the oscilloscope to measure that the signal amplitude is within the range
of 720 mV to 880 mV.
