The DDS1 features two output channels, which can provide sinusoidial signals from 100 kHz to 250 MHz with an amplitude around +2 dBm into 50 Ohm. It can be tied to a stable 10 MHz frequency reference.
The device operates in four modes, including single tone, amplitude modulation (AM), frequency modulation (FM), and phase modulation (PM). The four digital inputs allows fast switching based on an external modulation signal. The target application is control of acoustical optical modulators for switching laser frequencies and intensities.
The device is a modular unit to be powered by a Eurocard rack system (sold separately) and does not require a driver to operate, the host and device communicate only by a serial interface.
