The purpose of this investigation was to study the extracted times and timing resolutions for single photoelectron waveforms from a photomultiplier tube at different sample rates. This was done by taking waveforms from a high sample rate oscilloscope and downsampling them to the sample rates in question to serve as stand-ins for potential waveform digitizers at varying sample rates. Phase biases were found and algorithms were thus developed to counter these and provide cleaner timing.
