The attachment shows some test results from today for one SiPM of the type to be used on FPS, on a modified FEE board from IU developed for UCLA EIC HCAL prototype. This is close to the intended circuit and layout for real FPS FEE, except of course for the QT interface which is not included in these tests. I'm simply using an oscilloscope as the ADC here (integrating the digitized waveform on the scope).
