Shutter open signal attached at channel 8 is used as reference for the measurement window. This can be adapted in line 28 of the SetParameters.C file in the folder '/u/lascool/2025laserspectroscopy/kr_analysis/'.
Example:
fPar->piSoftwaregateLength = 20000; // How many CS after Shutter open used for signal in 4_LaserSteps/signal.
Currently, the common stop has a rate of 1.7838817 MHz divided by 89. This corresponds to approximately 50mus per common stop. With the setting of the example, the measurement window would be 1s after the shutter has opened. |
