Function Generator

 

The function generator creates sine, triangle, and square waves to be injected into a circuit. This instrument is functionally equivalent to the SPICE voltage source, but it adds easy frequency and amplitude changes. A node within the circuit must be specified to receive the function generator’s output signal. (the reference node is assumed to be ground.) The DC offset of the function generator’s output can be adjusted up and down. Pressing the “Setup” button toggles the height of the Function Generator, so that when its setup is complete, the it becomes only as tall as its display band.
