<p>The spot deflection in one co-ordinate direction is proportional to the test values and in the other co-ordinate direction is periodic. The screen is constructed from light emitting diodes (ni, k) arranged in rows (k) and columns (i), parallel to the two coordinate axes. Each l.e.d. is allocated to a row and a column. First terminals (A) of the l.e.d.'s in each row are joined together, and their second terminals (K) in each column are also joined together. L.e.d. terminals in a row are connected to an output of a digital measuring device (MW), to whose input the test value is applied, and terminals joined together in a column are connected to an output of an electronic stepping switch (S).</p> |
