MCS4 Series Multichannel Scaler

The MCS4 Series
The MCS4 series is a USB-connected, software controlled Multichannel Scaler. 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 maximum count rate is 400 MHz, dwelltime is ≥ 30 ns for one STOP input or ≥ 50ns for two STOP inputs. 

An 8 bit digital I/O port provides controlling external devices or to react on additional external signals.

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 MCS4 providing up to 12 MCS channels.

Our 2-Year Warranty covers also all types of MCS4 Series multichannel analyzers.
