The SR430 from Stanford Research Instruments is the first multichannel scaler which combines amplifiers, discriminators, bin clocks and data analysis in a single, integrated instrument. With its many features and its easy-to-use menu driven interface, the SR430 simplifies time-resolved photon counting experiments.

The SR430 Multichannel Scaler/Averager can be thought of as a photon counter that counts events as a function of time. A trigger starts the counter which segments photon count data into sequential time bins (up to 32k bins). The width of the bins can be set from 5ns to 10ms. The instrument records the number of photons that arrive in each bin.

The SR430 is useful in a variety of applications where it is necessaary to count events as a function of time: LIDAR, time of flight mass spectroscopy, and fluorescence decay measurements are just a few examples.
