PulseBlasterESR-PRO-II: High Speed Programmable Pulse Generator and Digital Word Generator

The PulseBlasterESR-Pro-II™ device is a high speed pulse/pattern generation unit. This design allows for functionality not found in the PulseBlasterESR-Pro. The PulseBlasterESR-Pro-II functions using a memory block and a control unit as opposed to the programmable microcontroller core used in the PulseBlasterESR-Pro. With this new design a new value can be generated on each output pin every clock cycle without the hindrance of instruction latency. This means pulses can be generated every clock cycle.

Key Specifications
