The TTi function generator range includes all-digital generators using DDS (direct digital synthesis), traditional analogue controlled function generators and digitally controlled analogue function generators.

In addition to the models shown on this page, the TGA series of universal generators incorporate both a DDS function generator and variable clock arbitrary generator within a single instrument. Go to the Arbitrary Generators page for details of these products.
