DAP 1200a

Obsolete

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.
