The MCA4A Series
The MCA4A series is a family of USB-connected, software controlled Multichannel Analyzers. The design is capable of converting incoming analog pulses (PHA mode) on up to 4 channels at virtually no conversion induced dead-time. Pulse Height Analysis can be performed using different fitting algorithms optimized for different input pulse forms and shaping times. A digital Pole Zero Filter and Trapezoidal Pulse Shaper enables to even process typical Pre-Amplifier signals. PHA data is transferred via the USB 3.0 interface in list-mode at a max. rate of > 1 M events / sec on each input. Four continuously every 8 ns sampling 16 bit ADCs with extraordinary stability enable 32k resolution for PHA mode. The availabilty of the simultaneous usage of the oscilloscope (Scope) mode together with a Fast Fourier Transformation (FFT) and software pulse height analysis allows for an easy setup and evaluation of the experiment. The PHA data can be tagged with the 8 digital I/O bits and also with the 8ns Real Time Clock. A set of eight 125 MHz 48bit Counter/Scalers is also optionally provided, 2 are presettable.
In MCS mode the four BNC connectors at the right are inputs with individually adjustable thresholds for Start, Stop1, Stop2, and channel advance signals to acquire time spectra. The internal memory is used to accumulate spectra of up to 16M bins. An automatic sequential mode allows to acquire up to 65536 sequential spectra – each with a presettable number of sweeps – with no dead-time between each cycle or synchronized with external signal. The minimum dwell time is 30 ns for 1 input channel and 50 ns for 2 channels and can be set in steps of 10 ns up to 781 h. The maximum count rate is 400 MHz.
An 8 bit digital I/O port provides controlling external devices or to react on additional external signals. It can be used for tag bits that are sampled with 2.5 µsec.
The “GO-LINE” compatibility allows to synchronize start and stop of the experiment across many measurement devices.
The 32 bit or 64 bit MPANT Windows Software is able to handle 6 MCA4A providing up to 24 MCA channels. In-field upgrade options enable upgrading of MCS mode, more MCA channels, 8 ns RTC time tagging, and multiparameter coincidences for 2 or 4 ADCs including Replay of list files.
Our 2-Year Warranty covers also all types of MCA4A Series multichannel analyzers.
