MCA4k

Multi-channel amplitude analyzer for spectrometric measurements.

Obrázek

    One of our projects for radiation measurements is the MCA4k. It is a compact single-board analyzer that can process signals from spectrometric or scintillation probes. Its main advantage is high stability and ease of configuration and control. It has a built-in digital oscilloscope, 4 digital inputs and outputs and independent metering of the internal high voltage for detection probes.

    The analyzer is intended for industrial as well as laboratory measurements, where the main requirements are ease of use together with a high level of configurability of the analyzer algorithms.  The unit features a completely independent autonomous mode of operation, whereby the measurement is configured and started from a computer via the USB port. The unit can then be disconnected and left alone to collect and process the data. Later on, the computer can be connected again for data and results download.
