Digital Pattern Generation
The DAQArb 5411 provides 16-bit digital pattern generation outputs at
the digital connector. This digital data is first synchronized to the
sample clock and then buffered and sent to the connector through a
80 Ω series resistor. The sample clock is also buffered and sent to the
digital connector to latch the data externally. Figure 4-23 shows the data
path for digital pattern generation. The digital pattern data is available
directly from the memory; it does not go through the digital filter.
