The upper 3 rows show the sample data together with the corresponding marker bits
and the expected output waveform of a marker channel.
The rising and the falling edge positions represent the information written into the
marker memory of the instrument.
5.2.1 Limitations
5.2.1.1 Marker Transition Density
The minimum distance between two rising or two falling edges of markers is 128 DAC
samples.
The following drawing shows some examples of rising and falling marker edge positions.
The distance is always more than 128 DAC samples.
