PBESR-PRO-500

High-speed programmable pulse signal generator

The PulseBlasterESR-PRO™ is a high-speed intelligent pulse/pattern/delay generator designed to output precisely timed TTL patterns.The PulseBlasterESR-PRO derives its intelligence from an embedded microprogramming controller core nicknamed “PulseBlasterESR-PRO “.
Nicknamed PulseBlaster™, the embedded microprogram controller core. The controller is capable of executing instructions, allowing it to control program flow like a general-purpose microcontroller.The PulseBlasterESR-PRO derives its speed from a maximum available clock frequency of 500 MHz.
The PulseBlasterESR-PRO's microprogram controller core differs from a general-purpose microcontroller in that it contains a microprocessor core.
Unlike general-purpose microcontrollers, which contain a highly optimized set of instructions developed specifically for timing and control applications, the PulseBlasterESR-PRO processor is unique in that the execution time of the instructions can be programmed by the user. This feature allows the PulseBlasterESR-PRO processor to execute complex timing patterns at different update rates ranging from nanoseconds to months.
nanoseconds to months, while the setup accuracy is always maintained to one clock cycle.
