The DAP 1200a is now Obsolete. For higher performance at a lower cost, upgrade your system for one of the PCI-bus DAP boards: the DAP 4000a.

If you need spare parts for a DAP 1200a system, compatible items are available.

The DAP 1200a is an excellent choice for applications where there is a need for real-time triggering, averaging, control, interpolation or a host of other functions, but no special high-speed requirements for FFTs or complex digital filtering.

The DAP 1200a:

  • has an onboard Intel 80C186XL 16-MHz or 20-MHz processor
  • is compatible with other a-Series boards
  • works with the AT ISA bus for 286/386/486/Pentium PC platforms
  • transfers data at high rates: up to 312K samples per second
  • allows fast real-time processing
  • offers low latency -- 1 ms per task -- for fast response
  • samples analog or digital inputs at rates up to 312K samples per second
  • updates analog outputs at rates up to 312K samples per second each
  • updates digital outputs at rates up to 312K samples per second
  • has expandable analog and digital inputs and outputs
  • complies with the EMC Directive 89/336/EEC

There is one DAP 1200a model: the DAP 1200a/6.

The DAP 1200a/6 is compatible with other a-Series boards and may be exchanged with them in any configuration.
