Multichannel Analyzers (MCAs) are workhorse instruments in many scientific measurements. An MCA analyzes a stream of voltage pulses and sorts them into a histogram, or “spectrum” of number of events, versus pulse-height, which may often relate to energy or time of arrival. The stored spectrum may then be displayed and analyzed.
ORTEC’s MCA offering is one of the world’s largest, providing solutions through a variety of formats. These types of MCAs include:
Basic Analog MCAs for routine applications:
- Standalone USB Connected MCAs
- NIM Modular MCAs
Digital all-in-a-PMT-Base MCAs with Bias Supply and Digital Signal Processors for use with Scintillation Radiation Detectors
Integrated Digital Workstation MCAs for use with HPGe Radiation Detector systems
Portable Digital MCAs for HPGe and Scintillation Radiation Detectors
