User-controllable Timing Signals

In order to meet the requirements for user-specific timing and
requirements for synchronizing multiple cards, the DAQ-/DAQe-/
PXI-2016/2010/2006/2005 card provides flexible user-controllable
timing signals to connect to external circuitry or additional cards.

The whole DAQ timing of the DAQ-/DAQe-/PXI-2016/2010/2006/
2005 card is composed of a bunch of counters and trigger signals
in the FPGA. These timing signals are related to the A/D, D/A con-
versions, and Timer/Counter applications. These timing signals
can be input to or output from the I/O connectors, SSI connector,
and the PXI bus. Therefore, the internal timing signals can be
used to control external devices or circuitry. Note that in other
models of DAQ-/DAQe-/PXI-2016/2010/2006/2005 card, the user-
controllable timing signals may vary. However, the SSI/PXI timing
signals remain the same for every DAQ-/DAQe-/PXI-2016/2010/
2006/2005 card.

We implemented signal multiplexers in the FPGA to individually
choose the desired timing signals for the DAQ operations, as
shown in the Figure 4-38

You can utilize the flexible timing signals through our software
drivers, then simply and correctly connect the signals with the
DAQ-/DAQe-/PXI-2016/2010/2006/2005 cards. Here is the sum-
mary of the DAQ timing signals and the corresponding functional-
ities for DAQ-/DAQe-/PXI-2016/2010/2006/2005 card.
