Description
This is an oscilloscope which is provided for the middle school teacher, with his own estimate and as his ordinary teaching implement.
We get it from a used colourless television receiyer. It is renewed to an oscilloscope. It comparatively holds linear amplification. On this case, the horizontal running can be varied 20-200Hz, and the frequency range of the vertical input is 10Hz-10kHz.
Especially it is as follows :
1. As the horizontal running is reduced from 60Hz to 20Hz, three waves of the commercial frequency appear on the same field.
2. Because of the wideness of the field, the apparatus is useful for the teacher and his many pupils.
3. The horizontal running and the observed wave is able to be easily synchronized each other.
4. We can get it with low cost.
