Test  Function  Generator

DL 2687

Module DL 2687 is a function generator such as: Dirac pulse, square wave and triangular wave selectable through selection switch.
At some terminals the output signal has a fixed amplitude; at other terminals the amplitude can be continuously adjusted, from 0 V to 10 V, through a potentiometer.
The frequency can be continuously adjusted, from 0.02 Hz to 10 Hz, through a potentiometer.
For what concerns the square wave, it is possible to set the ratio between high signal and period, by choosing between 1/2 and 9/10.
