Boxcar gate integrator averager

Overview

Boxcar gate integrator averager is a weak pulse signal detection system. It is suitable for continuous periodic waveform measurement or amplitude measurement of a single optical pulse. It is widely used in the measurement of phosphorescence effect, fluorescence lifetime and afterglow of LED. SRS pulse signal analysis and test system boxcar is used to obtain and analyze fast analog signals from background noise. After receiving the pulse light signal through the photomultiplier tube, it is converted into an electrical signal. After the electrical signal is input into boxcar, the pulse signal is recovered through boxcar. The principle is to set the data acquisition gate width in the range of 2ns ~ 150us according to the application needs. After repeated testing, the same signal is integrated first and then averaged, so as to eliminate the noise and recover the pulse signal. The repetition frequency can reach 50KHz, and has the functions of analog and digital signal output at the same time.
