Description
New electronic single board tester described here allows us to test and compare basic characteristics of new types of the APD (SiPMD, MCAPD, GAPD). The tester was realized in a portable form with graphics LCD and three controls buttons. It can measure statical and dynamical characteristics of the APD. We applied virtual periphery concept for very fast and simple way to measure the S/N resolution and own noise of the APD under investigation. The tester can be useful for long time monitoring.
Summary 500 words
The single board tester was designed basing on Virtual periphery concept. Simple
measurement can be do by this module. But also the tester connected to PC can be
used as a multichannel analyzer and a digital scope. New internal algorithm for the analysis of the experimental data based on Internal Negative Feedback model for the APD. It allows to obtain a value of Negative Feed-Back coefficient for SPICE model of the APD. The electronic module contains from 2x12 bit DAC, 22 bit ADC and 18 bit ADC and an internal high voltage converter (0-95V DC x 2 mA). For spectroscopic measurements (18 bit 1.8 MSPS) the module was connected to PC by USB (RS232). The experimental results obtained for MCAPD from Zecotech are presented.
