NEW 1-GHz Time Digitizer / MCS Offers High-Burst-Rate Time Spectrometry
from nanoseconds to milliseconds with 100-ps Precision

Oak Ridge, TN, May 23, 2002 -- Advanced Measurement Technology, Inc. a division of AMETEK, Inc. Paoli, PA. announced today the introduction of the Model 9353 100-ps Time Digitizer / MCS from ORTEC .. Model 9353 is a plug-in PCI card that functions as a time digitizer or a multichannel scaler. It measures the arrival times of Start pulses and multiple Stop pulses with a precision of 100 ps. Exceptional digitizing precision, speed and time span make it ideal for Electrospray Time-of-Flight Mass Spectrometry, Orthogonal-Acceleration MALDI TOF-MS, LIDAR, and Fluorescence/Phosphorescence Lifetime Spectrometry.

The Model 9353 measures the arrival times of multiple Stop pulses after the most recent Start pulse. Deep, cascaded FIFO buffers accommodate burst rates up to 1 GHz and sustained rates up to 10 MHz. The pulse-pair resolving time for Stop events is 1 ns. A dead time correction algorithm, implemented in software, permits increasing the Stop event rate by an order of magnitude, while keeping dead time distortions of the time spectrum insignificant. The Model 9353 is supplied complete with application software for data acquisition, display, manipulation and saving. Operating modes include time-of-flight and chromatograph/trend modes as well as histogramming and list modes. The software runs under Windows 98, NT, 2000 and XP.
