Page 5: １． Overview
Manual APU101 １． Overview Digital spectrometer APU101 (hereinafter referred to as this device) is a digital spectrometer that integrates a high- voltage power supply, preamplifier power supply, and MCA (multi-channel analyzer) into one. Since it is a multi-channel analyzer (MCA) equipped with a real-time digital signal processing function (DSP), waveform shaping processing by an analog circuit is not required, and a very high-speed A / D converter is used to directly digitalize the signal from the preamplifier. -
