The PulseBlaster DDS™ series of Intelligent Pattern and Waveform Generation boards from SpinCore Technologies, Inc., couples SpinCore’s unique Intelligent Pattern Generation processor core, dubbed PulseBlaster™, with dual Direct Digital Synthesis (DDS) units for use in system control and pulse generation.
The PulseBlaster’s state-of-the-art timing processor core provides all the necessary timing control signals required for overall system control and pulse synchronization. The additional DDS features allow the PulseBlaster DDS-IV-1000 to provide not only digital (TTL) but also two pairs of analog RF outputs generated by two independent quadrature data streams, ranging in frequency from 200 kHz to 400 MHz. This allows the PulseBlaster DDS-IV-1000 to meet high-performance and high-precision complex excitation/stimuli needs of demanding users. The quadrature output pairs allow for easy interfacing with analog quadrature modulators for single side band up-conversion.
