32K Digital Multichannel Series — SIM-MAX DMCA32S Series

The SIM-MAX DMCA32S series is a compact, single-channel digital spectrometer with a 32K channel count, independently developed by Xinman Sensing. It employs fully digital waveform sampling and FPGA-based algorithmic processing technologies. The device integrates a comprehensive suite of functions, including front-end signal polarity conversion, Analog-to-Digital Conversion (ADC), digital trapezoidal pulse shaping, automatic digital pole-zero cancellation, automatic baseline restoration, pulse pile-up rejection, a virtual oscilloscope, high- and low-frequency noise suppression, and zero-dead-time correction. Through the SIM-MAX spectral analysis and acquisition software, users can directly control the device and retrieve data, thereby fulfilling the requirements for signal acquisition and processing for various detectors, such as HPGe, NaI, LaBr3, and Cd(Zn)Te.
