Signal and Waveform Generator Products from TTi - Thurlby Thandar Instruments

 FUNCTION GENERATOR RANGE

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.

To read about the technical differences between types of analog and digital function generators click here.

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.
