64 channel scope with 64 analog triggers

ATD: Analog Threshold Detect, DSP module

D-TACQ units have long been used as a multi-channel live scope, with an external digital trigger. The ATD Analog Threshold Detect DSP module adds analog triggering where every channel can be a trigger sensor.

  • Logic demonstration: 64 simultaneous channels, 200kSPS/channel
  • Every channel can be a trigger channel, with individual MODE and level controls
    • MODE: RISING, FALLING, INSIDE, OUTSIDE.
    • Triggers may be
    • RAW: first channel declares a trigger, direct from the DSP module
    • GROUP: a group of channels declare a trigger
      • CURRENT: all channels in a group are valid at the same time.
      • HISTORY: all channels in a group have been valid during a period
      • FIRST_N: first N channels, a fraction of the whole group to trigger in either mode above.
    • Comprehensive EPICS support for scaleable network operation.
  • Previously available as a specialised application, it's now generalised to
    • An ADC in the ACQ42x range
    • Sample rate - 1kSPS to 200kSPS to 2000kSPS
    • Number of channels: 4 to 192 channels per box.
  • Advanced application

    • in a White Rabbit Distributed Scope, any channel in potentially 1000's of channels could declare a trigger to the whole system. Then , with pre-post capability, every unit can wind back time to the point of trigger.
  • Example Use-Cases:

    • ACQ1102+2xACQ423ELF : 64ch, 200kSPS
    • Z7IO+2xACQ424ELF : 64ch, 1000kSPS
    • Z7IO+2xACQ425ELF : 32ch, 2000kSPS
