11.16 Detect Modes
The DFX-7 has three selectable modes of detection: Z-Cross, Flank, and Peak. The
following diagram illustrates the difference between the options:
Z-Cross Flank Peak
Refer to the diagrams above. The current polarity is positive, as shown by the
position of the gate above the baseline:
Z-Cross: The detection occurs as the first positive half cycle crosses the baseline

Peak: The detection occurs at the highest peak in the gate.
The procedure to select the DETECT MODE is outlined below:
