PCI总线；100MHz,24路高速可编程TTL,脉冲波形发生器卡

PulseBlaster^TM is a general-purpose, multichannel, programmable TTL pulse generator / digital word generator. It offers up to 24 independently controlled channels, up to 64k instruction words, powerful program-flow features, and variable output rates ranging from ns to days per interval.

PulseBlaster^TM implements a novel 80-bit Very-Long Instruction Word (VLIW) architecture. Due to its versatility and intelligence, it is most commonly used as a powerful timing engine for applications requiring sophisticated pulse sequences and output patterns, precision timing of wide-ranging intervals, and complex system control.

The standard form factor is PCI, and standard clock frequency is 100 MHz. Compact-PCI boards and higher clock rates are available, currently up to 500 MHz.
