WebABSTRACT: A multichannel pulse-height analyzer system (MCA) consists of an ADC with 8192 channel performance, a histogramming memory, and a visual display of the histogram, implemented on a Personal Computer (PC). The purpose of the analog-to-digital converter (ADC) is to measure the maximum amplitude of an analog pulse, and

WebPulse-Height Analyzer Principle: Three pulses, 1, 2, and 3 are detected at different times t. Two discriminators emit a counting signal if their set voltage-level is reached by a pulse. Pulse 2 triggers the Lower Level E L but not the Upper Level E U. Pulse 2 is thus counted into the spectral region denoted as P. WebDescription. The DSA-LX analyzer is a full featured 16K channel integrated Multichannel Analyzer based on advanced digital signal processing techniques (DSP). When paired with a computer running Genie software the DSA-LX unit becomes a complete spectroscopy workstation, capable of the highest quality acquisition and analysis.
