LithPulser: An open-source pulse generator with 1 ns time resolution based on the Red Pitaya STEMlab 125-10 featuring real-time conditional logic for experimental control

Abstract

Many experiments in the physical sciences require high temporal resolution on multiple control channels and can benefit from conditional logic control of the experimental sequence patterns. We present LithPulser, a field programmable gate array (FPGA) based open-source digital pulser solution with 1 ns time resolution on 14 digital output channels. The pulser is set up on the affordable Xilinx Zynq-7010 FPGA in the form of the Red Pitaya STEMlab board 125-10. It offers up to 125 MHz bandwidth and a sequence duration of up to 4.2 s and features 16 sequence play control, including a conditional logic module reactive to input events in real-time. LithPulser is designed for a trial until success experimental use case.
