SR400 Notes

SR400 is a gated pulse counter produced by Stanford Research and often used for photon counting along with photon multiplication tubes (PMTs).

Recommended settings for CW mode operation, communicating through RS232

  • Mode
    • Count=A,B for T Preset
    • N periods = 1
    • At N=stop, Dwell=1s (which doesn't matter if Nperiods=1)
    • T=10 MHz (using internal clock), T set=1s
You can’t perform that action at this time.
