  • 16 bit wide data path with automatic hardware count clearing for greatly reduced acquisition time.
  • 100% PMS Probe compatible.
  • 16/32/64/128/256 Size channels, 32 bits each channel.
  • 1 Total count channel, 32 bits.
  • 1 Total strobe channel, 32 bits.
  • 1 Activity channel,16 bits.
  • 2 Spare channels, 32 bits each channel.
  • Probe house keeping data.
  • Built in 256 channel particle space monitor (PSM).
  • Spacing monitor bin widths adjustable from 0.25 µsec to 10 ms each.
  • 1 Channel reference and 7 utility A/D converter, 12 bits, ±5 mv to ±10 volts by jumper.
  • CAMAC version available.
  • 1.5 µs acquisition time for each size channel for a total of 384 µs for all 256 size channels (2.6 KHz maximum). 780 µs total acquisition time for a fully active setup (256 size channels, 256 strobe interval channels (PSM active), all auxiliary counters active).
  • Control register for range command (FSSP) and pump control (ASASP and PCASP).
  • House keeping data, eight channels.
  • Eight input analog differential channels (with input protection). Reference voltage plus seven utility analog channels (12 bits, ±5v or ±10v selectable by jumper, gain 1, 10 or 100 selectable by jumper, with 40 µs acquisition time per channel).
  • Integrated System Interface for stand alone operation (user configurable).
  • Single slot 16 bit full size ISA interface.
  • Up to eight interfaces per system.
  • 386, 486 and PENTIUM compatible.

Software Features
