Multichannel readout based on VATA64HDR16 spectroscopic ASIC. The silicon photomultiplier array (SiPM) - 4x4 elements - is attached. Total sensitive area is 2 cm2 with possible increase at least four times. The ASIC provides analog signal from all 64 channels by multiplexing the sampled values. The system is controlled by FPGA and communicates through USB interface. Bias voltage for the SiPM is applied externally.
