DESCRIPTION
The MCA527OEM / OEM+ is a compact and low power consuming multichannel analyzer PCB. Designed for the use of NaI- and CdZnTe- detectors, but it may be also usable for other applications such as neutron counters or CsI detectors and other low or medium resolution gamma detectors.
The OEM+ Version operates with 16k channel resolution and is usable for high-resolution HPGE detector purposes. The range of application can be in portal monitors, handheld devices or any other`s where an OEM Version meets customer equipment integration- and budget requirements.
The MCA527OEM / OEM+ is equipped with a RJ45 Ethernet socket and USB-B socket for flexible and immediate computer communication. The OEM is prepared for autonomous measurement modes with its on board μSD-card holder and software support. The software programs of our MCA family are available free of charge and allow to run in several operation modes such as a universal counter, oscilloscope, Gate Mode Autonomous Repeat Mode, Sample Mode or Multi Channel Scaling Mode.
