Digitally Delayed Frequency Synthesizer - SYN101

General Description:

The SYN101 modules generate two CW sinusoidal waveforms at frequencies up to 1 GHz with programmable delay. The SYN101 can be controlled by a PC via a USB interface. The module comprises two direct digital synthesizers (DDS), DS875, which have 30-bit frequency resolution and 11-bit phase resolution. Each DDS provides an independent RF channel with adjustable frequency from DC up to 1 GHz and adjustable phase from 0° ~ 360° in 11-bit resolution. The SYN101 is equipped with an on-board 2-GHz PLL clock source and powered by a 12V wall-mount AC adapter.
