Photon Counter / Multiscaler (MSA-300)

Discontinued - Please Use PMS-400A or DPC-230

  • Ultra-Fast Accumulation
  • High Repetition Rate
  • No Dead Time Between Sweeps / Channels
  • Input Pulse Width Down to 800 ps
  • Time / Channel Down to 5 ns
  • Count Rate Up to 100 MHz
  • Up to 512 k Points / Curve


The MSA-300 is a fast multiscaler for photon counting, time-of-flight measurements or other fast particle detection applications. By using a 128 bit memory structure a dead-time-free accumulation of subsequent sweeps is achieved. This makes the MSA-300 exceptionally useful for a wide variety of high-repetition rate signal recording applications.
