Getting Started Manual

set the levels to produce five monochrome stripes from left to right: grey, white, grey, black and grey again.

Our line signal thus looks like the drawing below:

In the instrument the number of horizontal points which make up the complete waveform is 1024, so the horizontal steps must be scaled to the range 0-1023.

Similarly, the full-scale signal amplitude is defined by values up to +511, so the vertical amplitudes must be scaled to to the range 0-511.

We can produce a table of all nine steps of the waveform (numbered 0 to 8), as follows:
