Circuit Board only MCA for Embedding into Devices
The MCA527OEM is a high performance circuit board only 2K Multi- Channel Analyzer/Multi-Channel Scaler. It is designed for use with NaI, CZT, LaBr and other low to medium resolution gamma detectors. Signal analysis is performed with a digital signal processor.
The primary applications are portal monitors, handheld devices and all other tasks where an OEM low cost MCA is needed, but size is not such critical that a MCA527micro is required.
The application programs from our MCA software family are free of charge and allows to operate the device as a general purpose multi channel analyzer, multi channel scaler, universal counter or oscilloscope.
Input DC coupled, offset adjustable and depending on polarity of input signal.
Linearity better than 0.1%.
Input voltage range ±1.6V
14bit, 10 MSps
Integral non-linearity <0.05%.
Temperature stability TK 50.
Digital signal processing
Double differential trigger filter, special slow trigger filter to support slow scintillation detectors as CsI or SrI.
Pile-up-suppression, pulse pair resolution ~400ns.
Automated and manual adjustment of trigger threshold.
Shaping time adjustable in the range 0.1 – 2μs.
Flat top adjustable 0 – 15μs.
Maximum number of channels: 2K
Differential non-linearity <1% for 2K resolution and 1μs shaping time.
Base line restorer.
PZC adjustment, detector decay time constants from 40μs to 1ms can be compensated.
Peak stabilization possible.
Direct input: for analyzing fall time < 40μs or
Gaussian shaped signals.
Oscilloscope mode shows signal as well as trigger filter and main filter signals.
Modes of operation
PHA (pulse height analysis), result is a histogram of pulse height.
MCS (multi channel scaling): registers number of counts in subsequent time intervals. MCS mode allows to acquire an integral PHA spectrum in parallel to the MCS acquisition.
Circuit board 136mm x 60mm, total length
with connectors 140mm.
Maximum height 18mm.
Miniature coax type MCX for gamma and counting channel input.
RJ45 connector for Ethernet.
USB-B socket for USB
JST PH06 for power supply.
Operational temperature range: -20 – 60°C.
Humidity up to 90%, non condensing
Customization to the capabilities of the
MCA527 if possible.
