Sum mode circumvents reset dead time between acquisitions
Up to 1,073,741,823 counts per channel in single or multiple passes
Automatic termination of data acquisition after a preset number of passes (up to 4 billion)
The start of the scan can trigger the experiment, or the experiment can trigger the start of the scan
Includes a ramp output generating adjustable sawtooth and triangular waveforms

The Model MCS-PCI-P is a PCI-bus plug-in card that converts a personal computer into a powerful and flexible Multi-Channel Scaler (MCS) or a multiple-stop time spectrometer. Powerful Windows software allows all controls and spectral manipulations to be implemented via on-screen displays. A dual-port memory on the card permits quick computer access to the spectral data for display purposes, without interrupting data acquisition by the MCS-PCI-P. With dwell times from 100 ns to 1300 s, a memory length of 65,536 channels, and input counting rates up to 150 MHz, the MCS-PCI-P has the flexibility to handle a wide variety of counting and timing applications.

In TOF-MS applications, the MCS-PCI-P can scan and acquire spectra on Quadrupole and Electrostatic /Magnetic-Sector Mass Spectrometers with a 15 ppm digital resolution
