PulseBlaster DDS-IV-1000: Programmable TTL and Dual Quadrature Stream Direct Digital Synthesis RF Pulse Generator
The
PulseBlaster DDS™
series of Intelligent Pattern and Waveform Generation boards from
SpinCore Technologies, Inc., couples SpinCore’s unique Intelligent
Pattern Generation processor cor
e,
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.
