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-II-300 to provide not only digital (TTL) but also analog output signals from two independent RF output channels, ranging in frequency from 5 kHz to 100 MHz. This allows the PulseBlaster DDS-II-300 to meet high-performance and high-precision complex excitation/stimuli needs of demanding users. The PulseBlaster DDS-II-300 also provides users the ability to control their systems through the generation of fully synchronized (digital and analog) excitation pulses from a small form factor USB board. The PulseBlaster DDS-II-300 also contains user-programmable Arbitrary Waveform Generation (AWG) capabilities for modulating the shape of the output waveforms for both analog outputs.

Key Specifications

• Four vectored interrupts with programmable Interrupt Service Routine (ISR) registers
• Interrupt enable registers to disable or enable interrupts on-the-fly
• User programmable registers to specify which “NORMAL” vs. “IMMEDIATE” interrupts
  • Normal Interrupt: Waits for the current instruction to complete, then performs the ISR and returns to the start of the next instruction
  • Immediate Interrupt: Stops the current instruction immediately, performs the ISR and then returns to the beginning of the next instruction

• Hardware and software interrupt triggers
• 96 bit instruction memory words for increased flag outputs
• 8K instruction memory words
• Programmable Pulse Program start address allowing the user to program the board once with multiple pulse programs, then pick the program entry point with a single write to the board
• Modifiable Pulse Programs while the core is running
• User programmable default return-to state for core flags when the core is not running, allowing for full control of flag outputs by the user when the core is STOPPED
• 16 Frequency registers for each DDS output
• 8 Phase registers for each DDS output
• 4 Amplitude registers for each DDS output
• All DDS registers are programmable while the PulseBalster Core is running

Applications

Complex, high-speed, multi-channel pulse, pattern, and word generation. Customers’ applications have included

• Complete high IF digital excitation system for high field NMR/MRI (just add mixers!).
• Complete bench test equipment for solid-state NMR probes (just add mixer and power amplifier!) - eliminates the need for wasting the precious magnet time.
• Build a multi-qubit NMR quantum computing device at a fraction of the cost of other solutions.
• Use it for all-digital CRAMPS, SFAM, and other "exotic" solid-state NMR experiments.
• Build a lock system.
• Build a demostration NMR system with/for your students
• Use it for Senior-Project and Masters' classes.
• Use with your microcoil probe.
• Build and control your own equipment for "hyphenated" experiments, LC-NMR, etc.
