Waveforms

How to obtain the waveform

1. Connect to the antenna input terminal (RF) a COLORBAR signal generator.

2. Adjust the controls of TV set (audio /picture) to normal. Adjust the volume to minimum.

3- 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 its adjustment.
