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.
