1Getting Started Introduction The U2761A is a 20 MHz USB modular function generator with Arbitrary waveform and pulse generation capabilities. It can operate as a standalone unit or as part of a modular unit when used with the U2781A USB modular instrument chassis. The U2761A adopts the latest direct digital synthesis (DDS) technology that digitally creates Arbitrary waveforms and frequencies from a single, fixed source frequency. DDS offers the precision of a digital control logic; reduc
