HOW TO OBTAIN WAVE FORMS
1. The indication at the schematic diagram , shows the place of measuring points of the respective wave forms, shown below. The place is not
exact, another point, in the same connection, can be used to have a measurement.
2. Connect to the terminal of antenna (RF), one signal generator - colorbar PAL-M.
3. Adjust the controls of TV set (audio /picture) to normal. Adjust the volume to minimum.
4- Every form of video wave should be visualized in the oscilloscope of wide band and low capacity test points (1 to 10 ). The form and peak amplitude
may vary depending on the oscilloscope and its adjustment.
