Data Acquisition (DAQ) and Control from Microstar Laboratories

DAP 1216a


The DAP 1216a is now Obsolete. For higher performance, upgrade your system for one of the PCI-bus DAP boards: the DAP 5216a.

If you need spare parts for a DAP 1216a system, compatible items are available.

The DAP 1216a Data Acquisition Processor boards combines high resolution analog data acquisition and intelligent processing. The DAP 1216a has the complete input/output and processing power of its 12-bit DAP 1200a counterpart. However, the DAP1216a acquires analog data with 16-bit resolution. It provides software-selectable sampling rates of up to 100K samples per second.

Note: The DAP 2416a/6 model still may be ordered by special request. However, the DAP 3216a provides a better value. DSP routines run on both the DAP 2416a and the DAP 3216a. On the DAP 2416a, DAPL passes these routines to the onboard DSP coprocessor for execution; on the DAP 3216a, DAPL 2000 -- the 32-bit implementation of DAPL -- executes DSP routines as optimized 32-bit code on the onboard DX4 processor. With this approach, the DAP 3216a outperforms the DAP 2416a on DSP commands as well as on non-DSP commands, and is a better value -- even for DSP-intensive applications.
