DAP 5200a
The DAP 5200a model brings many more real-time data acquisition and control applications within the scope of Windows systems. Its onboard 400 MHz processor substantially increases the real-time processing power of the top end of the DAP line. Real-time processing functions include smoothing, filtering, FFT, PID control, and responding to alarm conditions; the DAP 5200a also can scan high-speed data for trigger events in real time to capture pre-trigger as well as post-trigger data. Technical Note 164 shows the results for, among others, a 1024-point FFT (0.6 milliseconds per block) and FIR filters (0.2 microsecond overhead per channel plus 11 nanoseconds per tap – for a total time of 1.2 microseconds per output value for a 101-tap filter, for example).
