Basic Digital Operation Using Waveform Markers

Example of Incorrect Use

Waveform: 1022 points

Marker range: 110-1022

Marker polarity: Negative

This figure shows that a negative polarity marker goes low during the marker on points; the marker signal goes high during the off points. The ALC samples the waveform during the off marker points.

Sampling both on and off time sets the modulator circuitry incorrectly for higher signal levels. Note the increased amplitude at the beginning of the pulse.
