PulseBlasterUSB: Portable, Programmable TTL Pulse Generator / Digital Word Generator and Timing Engine

PulseBlaster USB 2U Rackmount Portable Programmable TTL Pulse Generator   PulseBlasterUSB Bare Board

   PulseBlasterUSB is a portable, stand-alone, programmable digital pulse (TTL levels), pattern, and word generator. The system is plug-and-play, controlled via USB, and includes an internal power supply (universal A/C input, 90-265 V). The elegant and sturdy plastic enclosure is stackable and well shielded internally, with built-in quiet cooling fan and detachable dust filter. USB drivers and C software for Windows XP and Linux are included, enabling the generation of complex pulse and pattern sequences for NMR, MRI, ultrasound, mass spectrometry, and related resonance and test technologies.
