Pulse Engine Overview

Device independent part of the program responsible for the generation of pulse sequences is called Pulse Engine. PPL script, PPL variables and Pulse Configuration serve as an input for Pulse Engine. Output of Pulse Engine are an event sequences for each hardware channel of Spectrometer.

Main components of Pulse Engine are:

• PPL compiler for Pulse Assembler code generation from PPL script.
• Interpreter of Pulse Assembler code.
• Pulse former and optimizer.
• Sequence validity checker.

PPL compiler generates an assembler code one time prior to the execution of experiment. Interpreter, pulse former and sequence checker are executed at every point of experiment if PPL variables are altered.

The parameters of Pulse Engine are stored in the Pulse Configuration, which can be created and edited by Pulse Setup Wizard.
