The WD-01 unit is designed for detection and recording of specific voltage level pulses in a noisy background. This is achieved by producing a pulse when the signal's peak is within the lower and upper window levels. The window levels are controlled by ten turn potentiometers and can be adjusted to ±10 V.
Gain selection of x1, x10 , x100, pre-selection for polarity of the peak detection and independent selection of the polarity for lower level and upper level signals are features for very flexible use in several applications.
