The MCA-3 Series

The MCA-3 Series is a family of PC-based, software controlled PCI-bus Multichannel Analyzers. The design is capable of converting incoming signals at upto 1,000,000 events/s. Two multiscaling inputs accept counting rates of more than 400 MHz. The minimum dwell-time is 100 ns.The large data memory can be segmented to enable to accumulate successive measurements. Spectra accumulated in sequential PHA mode can be displayed in a two-dimensional array.

For use in remote locations or where power outages are prevalent, an autostore function can be selected that will store both spectra and setup parameters at programmable intervals to prevent the loss of the acquireddata.

The MCA-3-Series boards can be remotely controlled by a host computer. "GO"-line compatibility enables the MCA's to start and stop accumulation synchronously with other FAST ComTec products such as the MS-12 Timer/Scaler, the MPA-3 Multiparameter System etc.
The MCA-3-Series Multichannel Analyzers are available in four versions - see the table below.

Our 3-Year Warranty covers also all types of MCA-3 Series multichannel analyzers.
